Weston-super-Mare’s Winterstoke Road Bridge Closing Until 2027 for Major Replacement

The Winterstoke Road Bridge in Weston-super-Mare, a vital crossing used by around 20,000 drivers each weekday, closed on November 24 for an 18-month replacement project, with reopening not anticipated until 2027.

Constructed during World War II to serve RAF Weston, the bridge has reached the end of its 80-year lifespan. Despite its current location in a residential area and no longer holding military significance, the Ministry of Defence remains the primary funder, covering most of the £20 million cost of replacing the aging structure.

To maintain accessibility for pedestrians and cyclists, a temporary footbridge has been installed over the railway line. However, drivers will need to follow a diversion route via Flowerdown Bridge. North Somerset Council has cautioned motorists that key points along the detour, including the Airport Roundabout and The Runway roundabout, are expected to experience heavy congestion. Commuters are advised to plan journeys carefully and consider avoiding peak travel times.

The replacement process will begin with relocating the utility cables and mains beneath the existing bridge. Following this, the old bridge will be demolished to make way for new foundations reaching 35 meters deep. The new bridge, measuring 60 meters long, will be fabricated off-site in sections and lifted into place by crane.

Council leader Mike Bell stressed the complexity of working above a live railway line, highlighting the careful planning required to minimize disruption to rail services and ensure safety.

The bridge’s heritage dates back to its construction during the Battle of Britain when it served an aircraft factory producing Bristol Beaufighters. The military design is still evident today, with the army green riveted metal sheeting lining its sides. Ownership and long-term maintenance of the new bridge will transfer to North Somerset Council, which plans for it to have a lifespan of 120 years.
