What are we doing?
This spring, we began construction on the temporary diversion of a section of the A43. This diversion is required so that we can build the new A43 overbridge that will carry traffic over the HS2 railway line. We recently installed narrowed lanes on the both sides of the A43, along with road safety barriers. These narrowed lanes will remain operational into winter.
During the construction of the temporary diversion on the A43, there will be some localised vegetation clearance as well as installing drainage underneath the road. These works will require overnight closures of the A43 no minimize disruption. As our works progress, there will also be periodic overnight lane closures on this section of the A43.
When will these works take place?
The A43 southbound will be fully closed overnight, from the Syresham Junction to the Brackley BP roundabout, from 8pm to 6am, on the following dates:
• Monday 2 October to Friday 6 October
• Monday 9 October
The A43 northbound will be fully closed overnight, from the Brackley BP roundabout to the Syresham Junction, from 8pm to 6am, on the following dates:
• Tuesday 10 October to Friday 13 October
To minimise disruption, when possible, we will reduce these full road closures to lane closures. Signage on the road will indicate if it is a single lane closure or full road closure with diversion.
The map above, shows the section of the A43 that will have overnight road closures from the Brackley BP roundabout to the Syresham Junction. The diversion route is via the A421, A422 and A5.
