Balsall Common Viaduct

About

Balsall Common Viaduct is a railway viaduct under construction in Balsall Common that will carry the High Speed 2 railway line. The finalised design of the viaduct was issued in February 2023; it will be a mostly concrete structure, comprising 16 piers and a bridge deck approximately 10 metres (33 feet) above ground. Various measures to mitigate acoustic, environmental, and community impact will be incorporated into the construction process and the finished viaduct. The viaduct is planned to finish in early 2027.

Design: The Balsall Common Viaduct will carry the railway line over Station Road, Bayleys Brook, the Heart of England Way, and the local floodplain. It will have a length of 425 metres (1,394 feet), be supported by 16 piers, and have a deck approximately 10 metres (33 feet) above ground. The piers have been designed to minimise their visual impact as much as possible while still fulfilling all relevant technical requirements as structural members. The viaduct will be constructed primarily of concrete and has been designed to require low levels of maintenance and to last for 120 years. The viaduct features barrier parapets that incorporate an integrated acoustic surface...
