High Speed 2 (HS2) works on National Highways network
HS2 is a new high-speed railway which will link London to Birmingham (Phase One) and then on to Manchester (Phase 2a), the East Midlands and Leeds (Phase 2b).
Phase One of HS2 has several direct interactions with our strategic road network of motorway and major A roads in the West Midlands, East Midlands and the South East. Construction of new structures, road widening and realignment of roads are required so that the high-speed line can effectively cross our road network. We are committed to working with HS2 Ltd and other partners to plan and co-ordinate our works programmes where we can.
Our roads network is vital to the running of the country and our customers and their safety remains our priority. While HS2 carry out these works we will make every effort to keep you updated and informed in advance of works to help you plan your journeys. We are committed to ensuring safety on our strategic road network and supporting a better-connected future.
These works are being co-ordinated and carried out by HS2 Ltd. For further information about HS2 you can contact HS2 directly. Details of the HS2 works on our network are below.

A46 near Kenilworth closed in both directions for two weekends in February 2025
High Speed Two (HS2) is the new high speed railway for Britain. Balfour Beatty VINCI (BBV) is working in partnership with HS2 Ltd to build the new high-speed railway.
BBV are constructing a box structure to take the new HS2 line under the A46 near Kenilworth.
This is being built off-line and will be moved into place using a “box push” technique across the existing carriageway in spring 2025. To prepare, for this BBV will need to alter the VRS (vehicle restraint system), central reservations layout and complete some advance works on the cross-carriageway drainage.
To complete these works safely BBV will install temporary full weekend closures of the A46.
Closure
To ensure the safety of the workforce, BBV will be closing a section of the A46 between Festival Island (Coventry) and Thickthorn Island (Kenilworth) over two weekends:
- 8pm Friday 7 February to 6am Monday 10 February
- 8pm Friday 14 February to 6am Monday 17 February
They will then require a final longer closure later in the spring 2025 to push the new box into place. Further details of those works will be shared after the weekend closures.
Following the weekend closures, there will be an ongoing lane closure northbound and narrow lanes to the southbound carriageway until the new box structure is in place in Spring 2025.
Diversion routes
Strategic HGV and through traffic diversion routes will be in place:
During the weekend closures all HGVs must follow the diversion routes. Please do not use sat navs and allow more time for your journeys.
- For HGVs travelling north to access Kenilworth, please continue on the A46 and leave at the Thickthorn Roundabout.
- For all other HGVs travelling north, beyond Kenilworth to Coventry, please use the M40, M42, M6 towards Coventry to rejoin the A46.
Local diversions routes will be in place.
