Weight and width restrictions enforced on Kendal bridges to ensure safety

Urgent safety measures are being enforced on two Kendal bridges following repeated breaches of weight restrictions that pose a risk of structural damage or collapse.

Brigsteer and Underbarrow bridges, crossing the A591, have been subject to a 7.5 tonne weight restriction after being classified as weak structures.

Monitoring has revealed nearly 30 breaches over 13 days, with heavy goods vehicles up to 40 tonnes observed making return journeys.

In response, Westmorland and Furness Council has introduced physical measures including a 6’6” width restriction to prevent larger vehicles from crossing.

These changes will be implemented through temporary traffic management with plans for permanent remodelling.

A 20mph speed limit will further ensure safe approach to the new restrictions.

Background of the Restrictions

Brigsteer and Underbarrow bridges, erected in the 1970s as reinforced concrete half joint structures, were closed in 2024 and reopened with a weight restriction that increased to 7.5 tonnes in February 2025.

These restrictions will remain as permanent measures, based on advice from consultant engineers.

Enforcement and Safety Concerns

The Council highlighted catastrophic risks if the bridges were overloaded, noting structural collapse onto the A591 below as a possible outcome.

The limited capacity of enforcement cameras to prevent breaches or effectively gauge vehicle weight makes physical restrictions necessary.

Even though alternative routes exist for larger vehicles, the Council acknowledges the impact of these measures on local businesses and logistics, though no compensation is available.

Councillor Peter Thornton emphasised the importance of immediate action to avoid potential structural failures and noted the need for funding commitments to find permanent solutions for these aging infrastructures.

Road users and affected businesses should take note of the changes and adjust their operations accordingly.
