TfL Introduces 18-Tonne Weight Restriction on Vauxhall Bridge Over Structural Concerns

Transport for London (TfL) is set to introduce a new 18-tonne weight restriction on Vauxhall Bridge from 1 July following recent structural assessments that identified signs of deterioration within the historic crossing.

TfL described the measure as “safety critical” and said the restriction will remain in place while engineers develop longer-term repair and strengthening plans for the bridge.

Despite the concerns, TfL stressed that Vauxhall Bridge remains safe to use and that the weight limit is being introduced as a precautionary measure to help prevent further deterioration.

Emergency service vehicles and buses will be exempt from the new restrictions, with no changes expected to existing bus routes.

Carl Eddleston, TfL’s Director of Streets and Network Operations, said:

“While the bridge remains safe, limiting heavier vehicles helps us protect and keep it open while we develop the long-term improvements it needs.”

A signed diversion route will be introduced for vehicles exceeding 18 tonnes travelling in both northbound and southbound directions.

Vauxhall Bridge currently carries around 39,500 vehicles every day, although TfL estimates only around 200 vehicles — approximately 0.5% of total daily traffic — exceed the new weight limit. These are primarily heavy goods vehicles.

The bridge has already been operating under previous restrictions since 2023, when TfL imposed limits on vehicles weighing more than 44 tonnes gross weight or 11.5 tonnes per axle.

Eddleston added:

“Safety is our top priority, and we know how important Vauxhall Bridge is for people travelling across London.

“This is why we’re taking this precautionary step to introduce a weight restriction to the bridge.

“We are sorry for any disruption caused by the restriction, and we’ll continue to monitor the area closely, ensuring we keep people updated as this work progresses.”

Growing Pressure on London’s Ageing Bridges

The new restrictions at Vauxhall Bridge come amid wider concerns over the condition of ageing bridge infrastructure across the capital.

Earlier this year, Albert Bridge in west London was closed to motor traffic after engineers discovered a crack in a cast-iron structural component. Repair costs are expected to reach approximately £8.5 million, with the bridge likely to remain closed for up to a year.

Meanwhile, Hammersmith Bridge has remained closed to motor vehicles since 2019 following the discovery of cracks in its pedestals, while Broadmead Road Bridge in Redbridge has also been shut to traffic since July 2023 due to structural concerns.

The increasing number of restrictions and closures has renewed focus on the long-term condition of bridges and structures across the UK road network, many of which are now decades beyond their original design life.

Last year, the Department for Transport announced a £1 billion investment package for local highways enhancement projects, including the creation of a dedicated structures fund aimed at helping local authorities repair and maintain bridges, tunnels and flyovers.

TfL has not yet confirmed when major repair works on Vauxhall Bridge could begin but said further updates will be provided as long-term plans are developed.
