High Speed 2 (HS2) works on National Highways network

HS2 represents a strategic investment in Britain’s future to create a modern railway for fast, frequent, reliable journeys. It supports the government’s mission to fix our railways, reversing decades of delays, cancellations and overcrowding across the network. 

HS2 is a vital part of the government’s mission to rebuild Britain and boost growth. By improving connections, the railway will create a corridor of economic opportunity between London and the West Midlands and promote social mobility. It will give people more freedom to choose where they live and work, and businesses more opportunities to trade and grow.

HS2 is a new high-speed railway which will link London to Birmingham.  The government has committed to fund the work to tunnel from Old Oak Common in west London to Euston, bringing services to the heart of the capital.  

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.

HS2 contractor Balfour Beatty VINCI (BBV) is working to construct the A5 Hints bypass Overbridge that will allow HS2 to pass under the A5. 

To continue the safe running of this roadworks scheme, BBV will need to undertake maintenance works of the CCTV cameras along this bypass. These works will need to close the A5 in both directions between Mile Oak and Weeford Junction to allow the maintenance of the cameras to take place. 

A signposted diversion will be in place and will be via the A38 and A453 Sutton Road for westbound traffic and A453 Sutton Road and A38 for eastbound traffic.

The overnight closures on the A5 Hints bypass in both directions will be between:

  • 9pm and 5am on 7 July 2025
  • 9pm and 5am on 11 August 2025
  • 9pm and 5am on 15 September 2025

HJS2 contractors Balfour Beatty VINCI continue with their ongoing construction work on the M42/M6 Link Road Viaducts. They will be extending the existing long-term traffic management measures on both the eastbound and westbound carriageways of the M42/M6 Link Road. 

On the eastbound carriageway, the hard shoulder will be closed from the M6 southbound at Junction 4A to the M42 (both northbound and southbound). 

On the westbound carriageway, the hard shoulder and one additional lane will be closed from the M42 southbound at Junction 8 to the M6 northbound at Junction 4A. 

A temporary 50mph speed limit will be in place on both carriageways for the duration of these works to ensure the safety of the road users and our workforce, the long-term traffic management will be in place from 1 July 2025 until 31 December 2027.

 

Long-term traffic management is now in place on the M42/M6 link road.

This involves closing lane one and the hard shoulder of the M42/M6 link road southbound connector.

This will reduce the lane availability from two running lanes of traffic to one and will be in place from 24 August 2023 until further notice.
