    Traffic management removed

    We’ve now completed construction of the new junction on the M49 motorway and removed the supporting traffic management. We’ll be completing our tree planting now it’s the autumn. So far, we’ve planted over 3000 trees around the new junction, but we’ll also be hydroseeding and planting more trees between now and November 2020. We need to carry out the planting during these months for optimal growth.

     As per our commitment in the government’s Road Investment Strategy, our completion of the junction will now allow local developers to build connecting roads into the stubs of the junction. From recent discussions, we’re aware that the developer has started design work and with the aim of starting construction in the near future.

     We’ll open the new junction to traffic once the link roads are completed and connected to the local road network.

Overview

 As per our commitment in the government’s Road Investment Strategy, our completion of the junction will allow local developers to build connecting roads into the stubs of the junction. From recent discussions, we’re aware that the developer has started design work and with the aim of starting construction in the near future.

We’ll open the new junction to traffic once the link roads are completed and connected to the local road network.

The new junction we've built on the M49 is located to the south of the Western Approach Distribution Park and west of the village of Easter Compton.

The design features a two-bridge junction. It uses the existing bridge at Farm Lane with a second bridge that we've built immediately next to it. The two bridges are incorporated into a single roundabout that spans the motorway. New access and exit slip roads have been built on both sides of the motorway junction so that it connects fully with both northbound and southbound traffic. The junction is now ready for the developers to build in the connecting roads.

The new bridge over the M49 also includes a dedicated lane for walkers, cyclists and other users.

We committed, along with South Gloucestershire Council, to unlocking the economic potential of the Avonmouth Severnside Enterprise Area. It's an important regional employment site and was previously the largest brownfield site in Western Europe.

As the port of Avonmouth and the Avonmouth Severnside Enterprise Area to the west of Bristol currently have no direct access to the M49, it has hindered proposals to support economic growth in the area. The new junction on the M49 opens these areas, and once the developers build the connecting roads, will ease congestion and contribute to the economic growth of the local area and wider region.

Since our construction started in December 2017, the site has already attracted new economic activity and associated employment in diverse sectors including, waste management, manufacturing, warehousing and distribution.
