Wolverton Viaduct is a railway bridge carrying the West Coast Main Line over the River Great Ouse to the north of Wolverton, part of Milton Keynes, in south-eastern England. Built in 1838 for the London and Birmingham Railway (L&BR) to the design of Robert Stephenson, it was the largest viaduct on the L&BR's route. It is in the centre of Wolverton Embankment, itself the largest on the line. It has six brick arches and covers a distance of 660 feet (200 metres), reaching a maximum height of 57 feet (17 metres) above the river, and terminating in substantial abutments which contain decorative arches. Several contemporary commentators likened Stephenson's bridges to Roman aqueducts. The viaduct was widened to take four tracks in the 1880s with a blue-brick extension, in contrast to the red-brick original. Masts for overhead electrification were added in the 1950s but otherwise the bridge is little changed since it was built and it is now a Grade II listed building. (Full article...)
