Central Government has provided £500,000 to South Gloucestershire Council to fund a study into a new Junction 18a on the M4 and link to the Avon Ring Road A4174. The study is being led by South Gloucestershire Council in partnership with Highways England


The Joint Transport Study directly refers to the scheme within the vision for Yate and East Fringe to Bristol: “The proposals in this area… focus on improving public transport and highway connectivity to the East Fringe and Yate… A new motorway junction on the M4 (Junction 18A), with connections to the Ring Road and Yate, will help to tackle traffic issues at M32 Junction 1 and provide a high quality route to Yate. This will unlock highway capacity for MetroBus improvements on the A432 corridor between Yate and Bristol, connecting into the North Fringe to Hengrove Package infrastructure which would also be further upgraded.”

To help inform the feasibility study on this project, South Gloucestershire Council is holding a public consultation.  You can access all supporting documents and the online survey from the consultation webpage.  The consultation period is open between Monday 21st August 2017 and Monday 16th October 2017.  To find out more and have your say:
