The Avon Aqueduct in Warwick crosses over the River Avon near to the boundary of Warwick and Leamington Spa. There is also another Avon Aqueduct in Scotland which is the second longest in the UK. The Warwickshire aqueduct was built in the late 18th century as part of the Warwick & Napton Canal which was intended to link the Warwick & Birmingham and Oxford Canals (at Napton natch). Now this is part of the Grand Union.
