M3 Chertsey Bridge

M3 Chertsey Bridge is a highway bridge crossing the River Thames in Surrey with three concrete spans designed to carry multiple lanes of motorway traffic. The structure connects both banks of the river and allows vehicles to pass over the water without obstruction.

The bridge was completed in 1971 as part of the expansion of motorway infrastructure across southern England. Its construction represented a major step forward in improving regional transport connections during that era.

The bridge creates a connection between the regions of Surrey and Middlesex, supporting the daily movement of local communities.

The bridge sits roughly 300 meters upstream from Chertsey Lock and provides a clearance height of about 6.5 meters for river traffic. The best views can be found from nearby riverside areas or the roads that approach the structure.

The bridge was designed with spans that cross the Thames without requiring any supporting piers to be placed directly in the water. This approach protected river navigation and minimized disruption to the waterway itself.
