171C, is a bridge over the Grand Union Canal in Wolverton, Milton Keynes in south-eastern England.

Wolverton Works, opened in 1838, was built by the London and Birmingham Railway (L&BR) as its main locomotive maintenance depot.

[1] The bridge, designed by Robert Stephenson, opened in 1838 when the LBR began running train services.

Thereafter, traffic over the bridge reduced and it ceased to carry passenger services, possibly explaining why it was never replaced.

The bridge now carries a single track, which is supported on the steel plate across the centre of the structure which was added in the 20th century.
