Grosvenor Bridge was designed by architect Thomas Harrison and opened in 1832. The Grade 1 listed structure was the largest single span stone arch bridge in the world when it opened. It carries the A483 over the River Dee in Chester.

Background

Unfortunately, the Bridge has been hit by vehicles twice in a six-month period - in March 2022 and then again in October 2022. In both cases, vehicles heading out of Chester failed to negotiate the left-hand bend onto the bridge and collided head on with the parapet. These impacts caused masonry blocks to fall on the footpath and cycleway below. Fortunately there were no injuries.

Latest update

Following an options appraisal exercise, a preferred solution has been taken forward to the detailed design stage. It will take some time to develop the solution into a buildable design, but we would hope to receive the completed design drawings within the next few months.

We are looking at ways to both strengthen the bridge to prevent falling masonry and reduce the likelihood of an impact in the first place, though options are limited by the road layout and the Grade 1 Listed status of the bridge.

Reconstruction costs will be recovered from the drivers' insurance policies but strengthening costs will be borne by the Council.
