Get ready for a notable M4 closure that will impact weekend travel plans. From 7 PM on Friday, October 24th, to 6 AM on Monday, October 27th, both directions of the M4 will be shut down between Junction 18 (Bath) and Junction 19 (M32). This closure is a critical step in the A432 Badminton Road bridge reconstruction, as eight massive steel beams are set to be hoisted into place.
This weekend’s work represents a major milestone in the project. While the closure is necessary, it’s important to note a slight shift in the original schedule. Sean Walsh, route manager for National Highways, explained, Due to unavoidable circumstances, we are having to move the weekend closure to the 24th October.
This adjustment stems from a delay in the production of the bridge beams. Walsh emphasized the importance of having all components ready before the closure to ensure a smooth operation. He added, Whilst the delay is regrettable, we are working at pace to reopen the A432 as soon as possible, and we don’t anticipate this will have a delay on the overall program of works.
The impact of this closure is expected to be substantial. During typical weekend peak periods, an estimated 3,000 to 4,000 vehicles per hour utilize this stretch of the M4. Drivers are strongly advised to seek choice routes or adjust their travel times to avoid the area.
For those needing to navigate the closure,National Highways has outlined diversion routes. Westbound traffic will be directed onto the A46, then the A420, and finally the A4174, rejoining the M32 at Junction 1 before connecting back to the M4 at Junction 19. The eastbound diversion follows the same route in reverse.
The new A432 Badminton Road bridge is designed to be a modern and robust structure. It will measure 46.5 meters in length and 20 meters in width, effectively spanning all eight lanes of the motorway. The design includes enhanced lane and pavement widths, bringing it up to current safety standards. Additionally, higher barriers will be installed to provide greater protection for pedestrians and cyclists.
The original Badminton Road bridge, built in 1966, was closed in july 2023 after a thorough structural assessment revealed significant issues. Following this, demolition and replacement where identified as the most efficient and cost-effective method to reinstate this vital transportation link.
Once the new steel beams are successfully installed this weekend,the remaining construction of the bridge is expected to proceed with minimal disruption to the motorway traffic below. the new bridge is slated to open to the public in early 2026. National Highways reports that the project is progressing well.
