A432 Badminton Road M4 overbridge closure
Latest update 24 October 2024
Background
The bridge was closed by National Highways on 12 July 2023 for detailed investigations after cracking and deterioration were identified during a routine structural inspection. Diversions have been in place ever since.
Its condition means the bridge needs replacing – which will take approximately 2 years – and must remain closed until then. Read the National Highways announcement on their website.
Work began to prepare for the bridge replacement in January 2024.
We are working with National Highways to consider any sustainable transport opportunities that the new bridge may provide.

What this means for local traffic
The bridge remains closed to all motorists. Access has been maintained for pedestrians and cyclists.
Motorists are advised to use the following diversions:
- northbound via the B4465 Westerleigh Road up to A46 and into Yate via A432
- southbound in reverse
National Highways is also encouraging all traffic to use the A420 and A46 for Yate from the Hicks Gate direction on the A4174, and motorway users to use the M4 junction 18 for Yate, rather than the M32 and A4174.
Additional restrictions
The following roads are temporarily closed to through traffic:
- Coalsack Lane
- Ruffet Road
- Cooks Lane
Access has been maintained for pedestrians, cyclists, horse riders and to residential properties and business premises along these roads.
These restrictions will remain in place for the foreseeable future but there are no plans to make them permanent.
Accessing businesses
All businesses either side of the bridge closure are still accessible and open as usual.
Hambrook lights junction
The right turn at Hambrook lights on the ring road will remain closed as the arrangements in place are the most efficient way of moving traffic through the junction along the ring road. This was demonstrated during the previous disruption associated with the Bromley Heath Viaduct work.
We will monitor the road network to identify any areas of congestion where we may need to intervene. You can contact our StreetCare team on A432bridgeclosure@southglos.gov.uk or 01454 868000.
Public transport
The Y6 Bristol to Chipping Sodbury (First Bus service) now includes the St Saviour’s Church area of Coalpit Heath on every journey. This will provide a regular service to this area while motorway overbridge remains closed. View the route information and timetable on the Travelwest website.
In addition, you can pre-book the WESTLink on demand bus service by phone 0117 457 8561 or via the app. You can find out more and download the app for Android or iOS from the Travelwest website.
Timescale
The project to replace the bridge is expected to take about 2 years. It is hoped construction of the new bridge will be completed in 2025.
October 2024 M4 closure
The M4 was closed in both directions between junctions 18 to 19 from 18 to 21 October to allow the utilities in the bridge to be diverted under the motorway. National Highways say this work has been successfully completed within the planned timescale.
October 2024 improvements to diversion routes
