    Works update and upcoming slip road closures

    We’re getting ready to start our essential repairs to St Georges Bridge. The bridge carries the M5 over the railway near junction 21 for Weston-super-Mare.

    We’re starting with repairs to the bridge from underneath the motorway. The M5 will be open as usual during this phase.

    Upcoming overnight slip road closures

    We will be carrying out survey works and repairs to the barriers on the M5 at junction 21, Weston super Mare.

    We will be closing the southbound entry slip road, as well as the northbound exit slip road at junction 21. 

    The closure will take place on:

    • Monday 18 November from 10pm until 6am.

    Diversion

    A well signed diversion route will be in place via junction 20 of the M5.

    The motorway will remain open throughout.

    Temporary access roads

    We’re setting up two temporary access roads to the east of the motorway. This will allow us to safely get people and equipment under the bridge.

    One temporary access road runs from the end of Station Road along the route of the M5 up to the railway line. This access road is now complete.

    Another will be to the north of the railway, and come off Wick Road. Works on this temporary access road started in October and is due to be completed in December.

    The temporary roads will remain in place until we finish our work under the bridge. The areas will then be reinstated to their current condition.

    Site compound

    Our site compound to the south of the A370 at the junction with Silver Moor Lane, is now in use by the team. However, there are still some works taking place to finish the compound. 

    This area provides site offices, welfare facilities and space to store materials. The compound will remain until all our work is complete.

    We’ll be carrying out this work in two phases. 

    The M5 will remain open for the majority of the works apart from a small number of full overnight closures. 

    Dates of any overnight closures will be communicated in advance via road signage and this webpage. 

    Phase one: November 2024 – summer 2026

    We’ll be starting with repairs to the bridge from underneath the motorway. The M5 will be open as usual during this phase.

    Phase two: spring 2025 – summer 2027

    This second phase will see us undertake the bridge deck refurbishment works on the motorway. This includes replacing the road surface, waterproofing and installing barriers on the sides of the bridge across both sides of the motorway.

    Bridge work to start under the motorway in September

    We’re carrying out this work in phases, starting with repairs to the bridge from underneath the motorway. The M5 will be open as usual during this phase.

    We will be setting up two temporary access roads to the east of the motorway to allow us to get people and equipment under the bridge. 

    One will run from the end of Station Road along the route of the M5 up to the railway line. Another will be to the north of the railway, and come off Wick Road. 

    There will also be a site compound to the south of the A370 at the junction with Silver Moor Lane. This will provide site offices, welfare facilities and space to store materials. 

    Work to set these up will start on Monday 2 September. The roads will be there until we finish our work under the bridge, when the areas will be returned to their current condition. The compound will remain until all our work is complete. 

    We’ll be starting work on the M5 carriageway next year. We’ll provide more details here as our work progresses.
