Marlow By-pass Bridge

Marlow By-pass Bridge is a road bridge that carries traffic across the River Thames, connecting Maidenhead in one county to High Wycombe in another via the A404. The structure uses a concrete cantilever design that allows wide road surfaces and adequate clearance for boats passing underneath.

The bridge was built in the early 1970s as part of a regional road development program aimed at improving traffic flow. It was constructed to meet growing transportation demands between the two counties as communities expanded.

The crossing serves boaters and local residents as a functional landmark that links two sides of the Thames, which remain quite different in character and use. People rely on the waters below for leisure and outdoor recreation.

The bridge is accessible by car and on foot, though it functions mainly as a traffic corridor rather than a destination for lingering. Visitors can view it from the riverside paths below or cross it by car to experience the span itself.

Below the bridge sits a boat storage area operated by Longridge, a nonprofit center for outdoor adventures on the Thames. This hidden function reveals how the infrastructure serves local communities in ways beyond regular traffic.
