Latest update 15 December 2023

National Highways has announced that the A432 M4 overbridge will remain closed for approximately two years while they replace the structure. You can read the announcement on their website.

Work will begin in January 2024.

You can read our response to the announcement, where you can also view a new video of Council Leader Claire Young and Co-Leader Ian Boulton discussing the situation.

Background

The bridge was closed in June 2023 for detailed investigations after cracking and deterioration were identified during a routine structural inspection. Diversions have been in place ever since.

A shuttle bus service was introduced in October, funded by National Highways. We continue to discuss what further measures may be possible to help residents with transport issues as a result of the bridge closure.

We are also 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.

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.

Free shuttle bus service

National Highways is funding a free shuttle bus for the communities affected by the closure of their bridge. You can check the timetable and route map on operator Transporabus’s website.

Timescale

The project to replace the bridge is expected to take about two years.

Due to the condition of the current bridge, it will remain closed. Demolition is planned for summer to autumn 2024. It is hoped construction of the new bridge will be completed in 2025.

National Highways are responsible for the bridge, the investigations and length of work. They can be contacted on info@nationalhighways.co.uk or 0300 123 5000.
