Definition of A33 road

The A33 is a major road in England. It consists of three sections: the first from Southampton to the southern end of the M3 motorway, the second from just north of Winchester to its junction with the A30 road; and the third from Basingstoke to Reading. The southern sections, formerly one of the two trunk roads to Southampton, has been bypassed by the M3, and as part of the planning approval, the old A33 Winchester bypass (a notorious bottleneck with traffic lights) was torn up and restored to grass. This was subject to direct action protests at Twyford Down.
