From Wikipedia, the free encyclopedia
The A423 road is a primary A road in England which leads from central Banbury to the A45 near Coventry. It starts in Banbury town centre and passes over the M40, from there it passes a few Warwickshire villages until it becomes part of the Southam by-pass, it then goes through Long Itchington and carries on until merging with the A45 near Ryton.
Its original route was from Tamworth in Staffordshire to Henley-on-Thames in Oxfordshire - almost 100 miles long. But on the completion of the M42 motorway in the early 1980s, the phase of the A423 between Tamworth and Coventry was downgraded to become a B-road.
The final downgrading came in 1990 when the M40 motorway between Oxford and Birmingham was completed. The remainder of the route beyond Warwickshire was renumbered to become part of various different A and B-roads, although it is briefly reprised as part of the Oxford Ring Road between the A34 Hinksey Hill interchange and the A4142/A4074 Heyford Hill roundabout. This is because the A4074 used to be the A423 prior to the M40 motorway being built.
