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.
