What are transport corridors, why they're being built, and which are the transport corridor projects in Bristol

We're working to improve our transport network to give more sustainable transport options.

Congestion, and its effect on air quality, is a major problem in Bristol.

Our road network is at capacity and will be under more pressure from growth in housing, jobs and regeneration.

To be an attractive place to work, live and visit, we need a transport network that enables people to move around efficiently with increased sustainable transport options that are available to all.

This is why we're working on projects to improve routes for bus services and for people to travel actively, which includes walking, wheeling and cycling.

Transport corridor improvements

Transport corridors, sometimes called strategic corridors, are generally linear and are used by multiple modes of transport.

The West of England Combined Authority are working with local councils, including Bristol, to develop and improve bus services in the region, in collaboration with bus operators.

In Bristol, projects include the:

  • City centre: covering Broadmead, Bedminster bridges, Redcliffe Way, Bond Street and Temple Way
  • A4 Portway: a 6 mile stretch of the A4 from Portway Park and Ride, along the Avon Gorge, to Hotwells, finishing near the Mardyke Wharf car park
  • Bus route 2: a 13 mile route along the A37 and A4018 connecting Henbury and Stockwood through the city centre

We have launched the Bristol on the Move website to bring the news, information, construction updates, and events together in one place for all 3 projects.

The West of England Combined Authority is also working on the A4 Bath to Bristol route and has now opened a consultation on the transport proposals, closing 2 December 2025.

Funding

Transport corridor projects are being funded by the government as part of the City Region Sustainable Transport Settlement, which is administered by the West of England Combined Authority.
