A significant portion of the M4 motorway is set to close in both directions over an entire weekend, causing interruptions for travellers, as a bridge dating back to 1966, showing signs of wear and tear, is due for demolition. National Highways has issued a warning about potential “substantial disruption and noise” during the demolition process. Following structural evaluations in July 2023 that revealed deteriorations and cracks on the southeast underside of the bridge, it was determined that demolition was necessary. This closure will affect both directions between junctions 18 (Bath) and 19 (M32) from Friday evening, March 21, to Monday morning, March 24.
The closure, as announced by National Highways, will commence at 7 pm on Friday, March 21, and will conclude by 6 am on Monday, March 24. While the demolition is expected to generate noise, efforts will be made to minimise disturbance as much as possible. With this section of the M4 being one of the busiest in the southwest, substantial disruptions are anticipated. Motorists are advised to avoid driving on the M4 near Bristol during the closure, and if travel is unavoidable, it is recommended to allow extra time for journeys using designated diversion routes.
National Highways has imposed an exclusion zone around the bridge for safety purposes. They have requested the public not to attempt to access the work site or to gather near the demolition area for safety reasons. To facilitate the upcoming demolition, the A432 Badminton Road bridge will also be closed to pedestrians and cyclists from Friday, March 7, with alternative routes provided via Down Road, Bury Hill and Church Lane. Additionally, the Cuckoo Lane junction on the A432 Badminton Road will be shut to all traffic over the demolition weekend starting from Thursday, March 20, with plans to reopen the junction on Monday, March 24.
During the closure of the Cuckoo Lane junction, access to Cuckoo Lane will be via Down Road and Bury Hill. Should the work not be completed as scheduled between March 21 and 24, further closures may be required. Following the demolition, preparations will begin for the construction of a new bridge, necessitating future closures of the M4 later in the year as part of the ongoing project. National Highways provided these essential details to ensure the public’s awareness and safety during the planned demolition and subsequent bridge construction.
The closure of this vital section of the M4 motorway is set to have a significant impact on travellers and commuters. The planned demolition of the aging bridge signals the start of a new phase of infrastructure development, aimed at enhancing safety and efficiency along this stretch of one of the UK’s key motorways. Motorists are urged to stay informed about alternative routes and to plan their journeys accordingly to minimise disruptions during the upcoming closure period. The cooperation of the public is vital to ensure the smooth progress of this essential maintenance work on the M4 motorway.
This significant closure comes as part of a necessary process to address infrastructure challenges, highlighting the ongoing efforts to maintain and enhance the UK’s transport networks. Construction and maintenance work on key roadways play a crucial role in ensuring the safety and functionality of the country’s motorway system. Your understanding and cooperation are vital during this necessary but disruptive phase of infrastructure development along the M4 motorway in the southwest region.
