Road Closure A6 Bypass

A6 road closure

Friday 30th June

The main construction work to repair the A6 on the carriageway leading on to the railway bridge will start next week – Monday, July 3. The first steps will be to set up the site compound and move all the required machinery and equipment into the location

The works remains on target to be completed by the end of August.

We would firstly like to extend a huge thank you to all road users and businesses in the local communities for their patience and apologise for the inconvenience this has caused.

Over the months, work has continued between our contractors and all associated parties to develop the best programme of repairs.

Planning has required significant collaboration and coordination as we are working in a location alongside Midland Mainline who have worked with us to develop the best way to proceed safely and efficiently. The application for permission to work alongside the rail line was submitted to Network Rail and this process took time to agree and approve design solutions to minimise the impact to rail users.

Collaborative work continues with Network Rail and all associated parties, including specialist contractors, and a repair solution has been agreed by all. We worked to amend the design of the repairs to ensure all licences were agreed following procedure and that everyone was happy with the way forward. This has not delayed progress and our main aim has always been to carry out the necessary repairs and reopen the A6.

Due to the proximity to the rail line the best way to repair this section of road is to not have deep excavations. Polymer injections will be used to stabilise the deep fill material. Following that backfill materials will be removed and the road surface will be reinstated.

This construction stage of the project requires four specialist contractors who will be working seven days a week, weekends where possible due to rail traffic. The main construction works will take place 7:00am – 7:00pm every day. Overnight working is not cost effective due to the solution being used and the rail line.

Northamptonshire County Council are committed to opening the A6 and funding is available for the repairs. We are still in discussion and seeking advice regarding options to recover the full cost of all of the work undertaken to date.

We have been working with our supply chain who have been on site, whilst the road is closed, to carry out works not associated with the emergency repairsWe have been taking advantage of the closure renewing road markings, road studs and signage. We will also be mowing, carrying out tree clearance, safety barrier inspections and barrier upgrades.

We realise traffic volume has increased on the local network. Once the A6 reopens we will inspect all local routes and ensure road surfaces, where affected, are repaired and bought up to standard required. We have continued to monitor and repair safety defects on local roads during the A6 emergency closure.

The main diversion route via the A14, the A43, A6003 and the A427 is still in place. Once repairs are completed all sections of the A6 will be reopened. Updates will be provided.

Thursday 11th May

The A6, Desborough bypass section, remains closed and the repairs required will be completed by the end of August. The key priority is to repair and open the A6 and funding is available for the repairs.

Following our routine inspection and maintenance in February damage was discovered to the approaches to the structure over the railway bridge. It was agreed that the route should be closed to traffic for safety.

Collaborative work continues with Network Rail and all associated parties, including specialist contractors, to develop and implement the repair solution. The works require significant coordinated planning because of the proximity to the Midland Mainline and the need to carry out repairs adjacent to a live railway line. We are actively working to amend the design of the repairs required in order to utilise the times available to fit in with the scheduled track possessions to help eliminate any impact on rail users.

We would like to take this opportunity to thank everyone for their understanding and patience, whilst this work continues. We realise the closure is disruptive and we continue to monitor the local area and traffic to minimise the impact to local communities.. In March we trialled re-opening the southbound lane of the A6 from Braybrooke Road to the A14 to relieve some of the traffic pressure in Desborough and Rothwell. This has worked well and feedback has been positive about this change to the traffic management relieving traffic congestion.

We understand congestion, and the increase in traffic in some areas, is a major concern. When Northamptonshire Highways close a road and put a diversion in place we must provide a diversion on a similar standard of road. The diversion route, which is clearly signed, is chosen to follow roads of a suitable standard and width to carry all traffic and avoid weight restrictions and we are doing all we can to ensure these routes are used.

The A6 is a busy road with a speed limit of 60mph and the approved diversion route uses similar grades of road. The main diversion route via the A14, the A43, A6003 and the A427 remains in place. This provides a safe route for vehicles unfamiliar with the area and local traffic.

Throughout the closure we are closely monitoring impact and have adjusted the closure, where we are able, and committed extra resource and signage to encourage drivers to follow this essential, and appropriate, diversion.

Thursday 23rd March

The closure to the Desborough bypass section of the A6 has been extended beyond the end of April as the damage is worse and repair work more complicated than initially thought. The A6 will be closed until the end of the summer school holidays.

Northamptonshire County Council will, today, trial re-opening the southbound lane of the A6 from Braybrooke Road to the A14 to relieve some of the traffic pressure in Desborough and Rothwell. We are aware of the effect that the closure has had on the local community and that is why we have decided to trial the opening up a section of the A6 in an attempt to alleviate some of the traffic pressure.

The A6 southbound opened this morning. We will be monitoring how this works and, if it has a significant negative impact, will have to close the section of the A6 again.

The main diversion route via the A14, the A43, A6003 and the A427 remains in place. This is very clearly signed and we are committed to encouraging vehicles not to use local roads as they are not suitable due to proximity to local communities and weight limits.

When Northamptonshire Highways close a road and put a diversion in place we must provide a diversion on a similar standard of road. Diversion routes are carefully chosen to follow roads of a suitable standard and width to carry all traffic and avoid weight restrictions.

The A6 is a busy road with a speed limit of 60mph and the approved diversion route uses similar grades of road. This provides a safe route for vehicles unfamiliar with the area and local traffic.

Extensive survey and investigation work has been carried out and repairs to the road where it joins the railway bridge are much more complicated than initially thought.

The works require significant collaboration and coordinated planning because of the proximity to the Midland Mainline and this process will take time to agree and put in place as we are working to minimise the impact.

The problems found on the carriageway leading on to the railway bridge are more severe than at the River Ise Bridge and there are logistical problems of carrying out repairs over a live railway line.

Because of these complications the work will not be completed until after the School Summer Holidays. The key priority is to repair and open the A6 as quickly as we are able to and every effort is being made to achieve this.

Northamptonshire County Council are committed to opening the A6 and funding is available for the repairs.The county council is working with all associated parties and identifying any funding available nationally for unusual situations such as this.

We would like to thank people and businesses in the local communities for their patience while this situation continues and apologise for the inconvenience this is causing.

For more information please go to Info on A6. The FAQ section will be updated by the end of this week.

Friday 10th March

Northamptonshire Highways have been carrying out investigative work on the A6 between Rothwell and Desborough since January 18th when a routine inspection showed there were faults under the carriageway on the approaches to the River Ise bridge. The road was closed with immediate effect to protect the safety of all road users. Works have been completed to repair this section of the road.

As repair works have been carried we continued investigative work along the closed section of the A6 bypass to ensure the rest of the carriageway and structures are up to standard.

This investigation work showed further faults on the approaches rail bridge on the stretch between Braybrooke Road and B576. The A6 runs over the rail line and identified foundation settlement issues which would pose a risk to road users if not repaired. On Monday February 20th an extension to the original road closure was agreed. Since then the A6 has remained fully closed from junction 3 of the A14 through to the B576 and currently it is expected to be closed until at least the end of April.

Survey works continue on this stretch of the A6 and we are working with all related partners to develop the best way to proceed safely and quickly carry out repairs and open the A6. The works are ongoing and funded by Northamptonshire County Council. They require significant collaboration and coordinated planning as we are now working in a location alongside Midland Mainline who we are working with us to develop the best way to proceed safely and efficiently. The application for permission to work alongside the rail line has been submitted to Network Rail and this process will take time to agree and put in place as we are working to minimise the impact.

We are working with all associated parties and are identifying any funding available nationally for isolated situations such as this. This does not, in any way, delay progress and our main aim is to carry out the necessary repairs and reopen the A6.

Monday 20th February

Northamptonshire Highways have been working on the Desborough bypass section of the A6, in both directions, between junction 3 of A14 at Rothwell and B576 roundabout.

Following a routine inspection of the A6 crossing the River Ise on Wednesday 18 January, Northamptonshire Highways took immediate action and closed the bridge due to safety concerns. The inspection uncovered road foundation failures. Repairs to this section of road started on Monday 30 January and have required significant resource and excavations to replace the failing foundations. As repair works have been carried out we have continued investigative work along the closed section of the A6 bypass to ensure the rest of the carriageway and structures are up to standard.

Over the weekend this investigative work extended along the section between Braybrooke Road to the B576 where failings have been shown on the approaches to the rail bridge. The A6 runs over the rail line and we have identified foundation settlement issues which would pose a risk to roadusers if not repaired. This will require an extension to the current road closure and mean the A6 will remain fully closed from junction 3 of the A14 through to the B576 until at least the end of April.

These investigation and repair works will continue over the coming weeks. We are working with Network Rail as this work has an impact on both the rail line and the carriageway.

Whilst every effort is being made to open the A6 as quickly as possible our ongoing work has shown that the section of the A6 in Northamptonshire has foundation failings. As investigations continue there remains the possibility we will find further issues that could extend the timescale of the road closure.

A spokesperson at Northamptonshire County Council said: 'The works we are carrying out have shown the importance of our routine highway inspections. Without these the issues would not have been uncovered. By finding these early we are able to undertake the repairs to the foundations to ensure the road remains safe and prevent further deterioration. We apologise for the extended time period of the closure but we believe the best thing to do is to address all issues on the bypass under one road closure. This way we can be confident we will not need to revisit the location again.

We'd like to thank road users and local residents for their continued patience while we complete our essential work and reassure everyone that we'll be doing everything we can to complete this work as quickly and safely as possible '

The diversion can be viewed on roadworks.org. We are speaking with local hauliers and urging drivers to follow this diversion.

From the north travelling south on the A6 drivers are asked to –

• Divert onto the A427 towards Corby;

• Traffic will continue along the A427 exiting at the A6003 roundabout.

• Traffic will continue along the A6003 (Uppingham Road) to its termination at the A43 roundabout.

• Traffic must then access the A43 (Southbound towards Kettering) and continue to junction 7 where it will leave the A43 and join the A14 travelling westbound towards Desborough and Rothwell.

• Traffic will then exit on to the A14 at junction 3.

Friday 17th February

Northamptonshire Highways has been working on the Desborough bypass section of the A6, in both directions, between junction 3 A14 at Rothwell and Braybrooke/Desborough road roundabout.

Following a routine inspection of the A6 crossing the River Ise, Northamptonshire Highways took immediate action and closed the bridge due to safety concerns on Wednesday 18 January. The inspection uncovered road foundation failures.

Repairs to this section of road started on Monday 30 January and has required significant resource and excavations to replace the failing foundations.

As repair works have been carried out we have continued investigative work along the closed section of the A6 bypass to ensure the rest of the carriageway is up to standard.

This weekend we will be temporarily extending the closure to include the section of the A6 between Braybrooke Road and the B576. This will allow us to continue with these precautionary investigations along the carriageway and on the rail bridge. We are liaising with Network Rail.

The road will be closed from 8am Saturday 18 to Monday 20 February. We are looking to open this up before the evening rushhour.

During this time the diversion will follow the route already in place.

Wednesday 8th February

This week progress has been good and we are still on schedule to complete the repair works by the end of February as long as the weather remains kind to us.

We have completed the excavation of the south side and have nearly completed the fill.

We are now moving to the north side and repeating the process, which is pulling up the road surface, excavating the foundations of the road and then fill. Once both locations are completed the road surface will be reinstated.

As this work is taking place we are continuing investigations to ensure the highway meets our standards.

The fault we found on January 18th was only discovered due to our routine inspection taking place which shows the importance of this process.

Frequently Asked Questions document and further information is available HERE

The images below show the south side excavated on Feb 2nd and the same location today. The fill is almost complete and the kerb line has been reinstated.

Friday 3rd February

We are currently working on the south side of the bridge over the River Ise and have carried out extensive excavations and started to rebuild the foundations of the road.

Next week we will be moving across to the north side to excavate and rebuild.

To date our investigations have not shown the concrete structure itself to be damaged.

We are on programme, weather dependant, to complete these emergency repair works by February 28th.

Northamptonshire Highways would like to thank everyone for their ongoing patience during the closure of the A6 and your cooperation.

A6 road closure

Tuesday January 31

Northamptonshire Highways would like to thank everyone for their ongoing patience during the closure of the A6 and your cooperation.

As you are aware our investigation work showed that the initial findings are more significant than originally thought. The work involved is extensive and we have been mobilising our teams and securing the specialist equipment. Repair works started Monday January 30. We now have our site compound installed and works have started to excavate the area. To date we have removed the affected road surface and are currently waiting for it to be tested. This is something we have to do to ensure it is safe and can be removed from site. This week we will continue to test and remove materials.

Temporary change to diversion route this weekend

Network Rail must carry out planned works to replace the railway bridge (Barford Bridge) on the A6003. This is part of a much wider scheme on the busy railway network and requires the A6003 to close temporarily.

During this time the A6 diversion will be temporarily changed to accommodate their works and the need for a closure.

The first change will be this weekend. Saturday February 4 from midnight and will continue until 6am on Monday, February 6.

A signed diversion route will be in place taking traffic on the A43 Corby Link Road to the A427.

The official A6 diversion route will be in place outside these hours and is highlighted in the attached FAQs.

This A6 repair works are weather dependant and should be completed by the end of February.

Please find attached our Frequently Asked Questions document which we will continue to update. This will also be available HERE

A6 road closure

Northamptonshire Highways would like to thank everyone for their patience following the closure of the A6 last Wednesday (18th January) and your cooperation in following the signed diversion.

In recent days we have reviewed all diversion signage and provided additional information where necessary.

We do realise how inconvenient this closure is. In everything we do, Northamptonshire Highways must put safety first. A routine inspection and drainage maintenance last week uncovered significant road foundation failure making it unsafe for vehicles to continue to use the road.

The bridge structure itself does appear to not be affected. However, the approaches to the bridge on the A6 has been shown to be unstable and unsafe, in both directions, between junction 3 A14 at Rothwell and Braybrook/Desborough road roundabout.

We realise people are concerned about the swift closure but we had to make this decision for the safety of all road users. On the night of the closure we immediately began to use all channels of communication to alert people to the closure. At this stage we were unsure as to the severity of the issue. Surveys in the following days showed that the stability of the carriageway is being compromised and that, although the road surface looks good, underneath the foundations are sinking and, in areas, voids or holes have appeared below the carriageway surface.

Last weekend we continued our investigations using ground penetrating radar surveys which showed that the initial findings are more significant than originally thought. The work involved is extensive and we have been mobilising these teams and securing the specialist equipment and will begin the repair works Monday January 30th. This work will be weather dependant and should be completed by the end of February. We will continue to provide progress updates.

We realise traffic volume has increased on the local network and are inspecting these roads for adverse impact and defects and will be repairing them during the A6 emergency works. Once the A6 reopens we will also inspect all local routes and ensure road surfaces, where affected, are repaired and bought up to standard.

When Northamptonshire Highways close a road and put a diversion in place we must provide a diversion on a similar standard of road. Diversion routes are carefully chosen to follow roads of a suitable standard and width to carry all traffic and avoids weight restrictions.

The A6 is a busy road with a speed limit of 60mph and the approved diversion route uses similar grades of road. This provides a safe route for vehicles unfamiliar with the area and local traffic. This also means we can minimise the impact on local communities.

We have also been speaking with local hauliers and advising drivers with this diversion.

From the north travelling south on the A6 drivers are asked to –

  • Divert onto the A427 towards Corby;
  • Traffic will continue along the A427 exiting at the A6003 roundabout.
  • Traffic will continue along the A6003 (Uppingham road) to its termination at the A43 roundabout.
  • Traffic must then access the A43 (Southbound towards Kettering) and continue to junction 7 where it will leave the A43 and join the A14 travelling westbound towards Desborough and Rothwell.
  • Traffic will then exit the A14 at junction

Diversion route

The diversion route can be viewed at roadworks.org

Update 24th January

Desborough Town Council continue to liaise with Northamptonshire County Council Highways who are exploring all possible options to alleviate the traffic problems through Desborough.

Update 23rd January

Northamptonshire Highways has been working, since Wednesday 18th January, on a section of the A6, in both directions, between junction 3 A14 at Rothwell and Braybrook/Desborough road roundabout.

An emergency closure was put in place to enable the necessary investigations to be made and extensive engineering surveys continued over the weekend.

Northamptonshire Highways has taken the decision to keep the A6 closed. This is following a review which has shown the issues to be more significant and the condition of the road is a safety risk. We are now starting works with all our partners and have specialist teams on site and plan to re-open the road at the end of February. The works we are undertaking will also be affected by adverse weather.

All roadusers are advised to avoid the area or follow the signed alternative route. The diversion follows the most appropriate route and is for all vehicles as there are weight restrictions which must be observed. Please follow the official diversion which is clearly signed and shown on roadworks.org.

The signed route diverts traffic from the A6 onto the A427 junction towards Corby; traffic will continue along the A427 exiting at the A6003 roundabout. Traffic will continue along the A6003 (Uppingham road) to its termination at the A43 roundabout. Traffic must then access the A43 (Southbound towards Kettering) and continue to junction 7 where traffic will leave the A43 and join the A14 travelling westbound towards Desborough and Rothwell. Traffic will then exit the A14 at junction 3 to re-join the A6. We are monitoring this diversion route at all times.

We would like to apologise for this extended closure and the inconvenience this is causing. Northamptonshire Highways is committed to safety and this route must remain closed until we feel it is safe to reopen.

There will be regular updates on Twitter at @nnhighways.

Updates will also be available at northamptonsdhire.gov.uk

Update 19th January

Please remember the A6 will remain closed tomorrow, Monday 23rd January, pending investigations which have continued over the weekend.

Northamptonshire Highways has been working on a section of the A6, in both directions, between junction 3 A14 at Rothwell and Braybrook/Desborough road roundabout.

Following a routine inspection on Wednesday 18th January Northamptonshire Highways took the decision to close this section of the A6 with immediate effect. This is due to safety concerns.
