Locks: Grand Union Canal North 24 - 46

Grand Union Main Line Northern section, locks 24 - 46: Warwick to Knowle

The Grand Union Canal Main Line runs for 137 miles through 166 locks from Brentford on the River Thames to Salford Junction in the north east of Birmingham. All the locks are double width locks except the final 11 locks in Birmingham. The locks on the Knowle flight are the first double width locks heading south from Birmingham.

The Grand Union Canal was formed in 1929 from many separate canal systems. The Main Line itself was formed from the following four canals:

- Birmingham & Warwick Junction Canal (Salford to Bordesley)
- Warwick & Birmingham Canal (Bordesely to Warwick)
- Warwick & Napton Canal (Warwick to Napton)
- Grand Junction Canal (Brentford to Braunston)

There is a five mile section from Braunston to Napton which is actually the Oxford canal. This section was never bought by the Grand Union Canal Company.
