|Route outline (key)|
In the mid-1920s, the A4007 was extended west along what was originally the A332 to meet the A4 on the edge of Slough. The A412 ended on it in Iver Heath so in 1935 the road west of there was renumbered the more logical A412.
This situation remained until the building of the Uxbridge town centre bypass, taking the A4020 away from the High Street, which also took traffic away from Vine Street. Apart from a short section near Cowley Road which is part of a gyratory on the A4020 Vine Street has now been declassified leaving the A4007 running from Iver Heath to Uxbridge.
