Crosskeys Bridge is a swing bridge that spans the tidal River Nene in Sutton Bridge, Lincolnshire. When it was built in 1897, it was the third bridge to cross the Nene in Sutton Bridge. The bridge is still in use today carrying the busy A17 between Lincolnshire and Norfolk. It was originally a dual purpose bridge serving the Midland and Great Northern Joint Railway Company on what is now the westbound carriageway and the road was on the eastbound side.
