Aldersley Junction is where the Birmingham Main Line Canal terminates and meets the Staffordshire and Worcestershire Canal near to Oxley, north Wolverhampton. It lies 1 km (0.6 miles) south of Autherley Junction (see entry) where the Shropshire Union Canal terminates and meets the Staffordshire & Worcestershire Canal.
When opened in 1835, the Shropshire Union was called the Birmingham & Liverpool Junction Canal. Almost immediately, most of the traffic which had previously used Aldersley Junction and travelled northwards on the Staffordshire & Worcestershire Canal now used the new canal, and so only travelled for the half mile between the two junctions. The Staffordshire & Worcestershire company raised the tolls to a very high level, to compensate for the loss of revenue.
In order to resolve the situation, the Birmingham Canal company worked with the Liverpool Junction company, and proposed the Tettenhall and Autherley Canal and Aqueduct. This would have left the Birmingham Canal just above lock 19, crossed the Staffordshire & Worcestershire Canal just below Aldersley Junction by an aqueduct made of iron, and then dropped down through three locks to join the Liverpool Junction Canal above the stop lock. The plans were drawn up by Birmingham surveyors, Dugdale Houghton, but the canal was never constructed, as the Staffordshire & Worcestershire company reduced their tolls rather than lose them altogether.
By road: Off A449 in Oxley, close to Dunstall Park Stadium on the northern outskirts of Wolverhampton. but best approached by boat.
