The Orwell Bridge is a concrete box girder bridge just south of Ipswich in Suffolk, England. Opened to road traffic in 1982, the bridge carries the A14 road over the River Orwell. The main span is 190 metres which, at the time of its construction, was the longest pre-stressed concrete span in use in the UK. The two spans adjacent to the main span are 106m, known as anchor spans. Most of the other spans are 59m. The total length is 1,287 metres from Wherstead to the site of the former Ipswich Airport. The width is 24 metres with an air draft of 43 metres; the bridge had to be at least 41 metres high. The approach roads were designed by CH Dobbie & Partners of Cardiff, later bought by Babtie, Shaw and Morton then Jacobs in 2004.
