M49 Avonmouth Junction

Scheme outline

Construction of a new interchange on the M49 at the site of the current Farm Lane overbridge, providing access from the motorway to the industrial areas of Avonmouth and the Severnside Enterprise Area.

The preferred design for the new junction will be a two-bridge roundabout interchange, using the existing overbridge to carry one side of the roundabout.

A junction serving Avonmouth has been proposed for the M49 since the road was being planned in the early 1990s and the access roads serving the large industrial complexes nearby have been planned with the location of the future junction in mind.

No timescale for the project has been formally announced, but press releases suggest that Highways England hopes to begin construction by the end of 2017.
