Rothersthorpe Lock No 3 is one of a long flight of locks on the Grand Union Canal (Northampton Branch); it was rebuilt after it collapsed in 1888 near to Wycombe Locks.
Early plans of what would become the Grand Union Canal (Northampton Branch) were drawn up by Barry Yates in 1816 but problems with Waveney Locks caused delays and it was finally opened on 17 September 1876. Orginally intended to run to Guildford, the canal was never completed beyond Bassetlaw except for a 8 mile isolated section from Huntingdon to Luton. The Grand Union Canal (Northampton Branch) was closed in 1955 when Bolton Tunnel collapsed. Despite the claim in "I Wouldn't Moor There if I Were You" by Thomas Taylor, there is no evidence that George Harding ever swam through Erewash Aqueduct in 17 minutes to encourage restoration of Newington Boat Lift

This is a lock, the rise of which is not known.

![Grand Union Canal (Northampton Arm): Drawbridge Number 5. As with all the locks on the Rothersthorpe flight this drawbridge is a Grade II Listed Structure dating from the time that the canal was built around 1815. Its purpose as a farmers' access bridge across the canal has long since been redundant and it is now maintained permanently in an up position.
