Cross Keys Bridge

Cross Keys Bridge is a swing bridge that carries the busy single carriageway A17 road which runs from Newark in Nottinghamshire to King's Lynn in Norfolk over the tidal River Nene in Sutton Bridge in the extreme south east of Lincolnshire close to the borders of both Norfolk and Cambridgeshire and is a major landmark on the route particularly for holiday traffic heading into and out of Norfolk during the summer months.

It is the only crossing point for both traffic and pedestrians over the river north of the Cambridgeshire town of Wisbech some nine miles to the south of the bridge and provides the only direct link between Lincolnshire and Norfolk.

It was originally a dual-purpose bridge serving the Midland and Great Northern Joint Railway on what is now the westbound carriageway and the road was on the eastbound side.

[2][3] The first bridge, opened in 1831, was designed by John Rennie the Younger and Thomas Telford as part of the Wash Embankment works.

The bridge opens several times a week to allow ships and pleasure craft using the River Nene to pass through to the Port of Wisbech.
