The project faced significant challenges over the summer due to exceptionally high rail temperatures, which necessitated the suspension of piling work adjacent to the operational railway. These extreme conditions, including multiple heatwaves during Britain's hottest summer on record in 2026, led to the introduction of strict safety controls by Network Rail to prevent track instability.
As steel railway tracks expand under heat, they create internal pressure. Construction activities, particularly those disturbing the ground near the track, pose a risk of instability if rail temperatures exceed predetermined safety limits. These preventative measures are standard industry practice to ensure the safety of workers and passengers.
The delays incurred around the railway operations mean the replacement bridge is now expected to be completed at the start of 2028. However, North Somerset Council and Octavius are actively exploring all avenues to bring this date forward.
The Winterstoke Road Bridge, a vital route in Weston-super-Mare, is being replaced at the cost of the MOD. The original World War Two-era structure was demolished over Christmas 2025 due to significant structural issues. The new bridge is designed to serve the route for the next 120 years.
Work since demolition has included the installation of 35-metre-deep piles to stabilise poor ground conditions, a prerequisite for building the new bridge. Some essential construction tasks are restricted to scheduled railway closures, often limited to late nights and weekends.
“"I’m sorry that people will have to wait longer for this route to reopen. We know the closure is affecting journeys, and residents deserve a clear explanation of the delay and what happens next."
Councillor Mike Bell stated, "We are reviewing the remaining construction timetable with our contractor, Octavius, to identify whether any work can be brought forward or rephased. Our priority is to get the route open to vehicles as early as possible. We will publish a further update as soon as we can, including the next construction milestones and any changes to the expected completion date."
“"Over the summer, prolonged periods of exceptionally high rail temperatures resulted in strict railway safety controls for activities within the track support zone. A key element of the replacement of Winterstoke Bridge involves piling operations adjacent to the operational railway. During these periods of extreme heat, activities could not safely proceed due to the potential impact on track stability. These are industry-wide safety requirements designed to protect passengers, freight services and the railway network."
Matt Whale added, "Despite these unprecedented conditions, the project team worked proactively with Network Rail and others throughout the summer to identify alternative working methods, re-sequence activities and maximise progress whenever conditions allowed. Whilst these challenges have affected the current programme, they have also demonstrated the strength of the partnership delivering the scheme. Through close collaboration, innovation and a relentless focus on safety, the team has continued to move the project forward and remains committed to delivering a high-quality asset that will provide long-term benefits for the local community."
