Maidenhead Railway Bridge

About

Maidenhead Railway Bridge, also known as Maidenhead Viaduct and The Sounding Arch, carries the Great Western Main Line (GWML) over the River Thames between Maidenhead, Berkshire and Taplow, Buckinghamshire, England. It is a single structure of two tall, wide red-brick arches buttressed by two over-land smaller arches. It crosses the river on the Maidenhead-Bray Reach, between Boulter's Lock and Bray Lock, and is near-centrally rooted in the downstream end of a very small island.

The Maidenhead Bridge was designed by the Great Western Railway Company engineer, the noted mechanical and civil engineer Isambard Kingdom Brunel. It was completed in 1838, but not brought into use until 1 July 1839. While it was being constructed, the innovative low-rise arches of the structure attracted considerable criticism and controversy, relating to their alleged lack of stability.

As a result, the centring for the arches was left in place until its destruction during a heavy storm in late 1839, despite which the arches stayed up, effectively vindicating Brunel's design. During 1861, dual-gauge track was installed across the structure, allowing both broad gauge and standard gauge services to cross it...
