Location

The bridge was originally constructed in wood by Isambard Kingdom Brunel as part of the Wycombe Railway, opened in 1854 and operated in broad gauge until 1870.^[2] The narrow spans were unpopular with river traffic and the bridge was reconstructed in steel in 1895. A footbridge, cantilevered out from the railway bridge was added in 1992, to take the Thames Path across the river;^[3] this substitutes for the historical towpath crossing point at Spade Oak ferry, about 1 km upstream of the bridge.^[4]

In 2013, the bridge was restored and repainted in green, and a large number of rivets which had rusted away were replaced. The restoration took nearly a year to complete, being finished in December.^[5] There was a plan to electrify the line,^[6] but due to cost overruns during electrifying the GWR main line, this has apparently been postponed indefinitely.
