 The road provides the major link between Leamington/Warwick and north-east Warwickshire, including Rugby and the M45/M1 motorways.The M45/M1 provided the major route to London until the early 1990s but have now been superseded by the M40, which passes to the south of the Leamington/Warwick conurbation.The A445 begins in central Warwick at a junction with the A425 as Smith Street, and the first part of it is single carriageway.
