|Route outline (key)|
The B462 is a semi-rural B-road near Watford in Hertfordshire. It starts at a mini-roundabout in the centre of Radlett on the A5183 (former A5) and heads roughly westwards along Watford Road – but takes some time to get out of town. Kemprow and Aldenham are bypassed, although the original route of the road went through these places.
The route passes under the M1 a short distance to the south of junction 5 of the motorway. Immediately afterwards is a roundabout on the A41 Watford bypass. The road then continues southwestwards, going through a green area adjacent to the Queens' School and Police Sports Ground. It enters Oxhey before ending at a set of traffic lights on the A411 (former A41).
The B462 originally continued on for another block but this section has now been taken over by the A411 one-way system. The section of the B462 south of the A41 was renumbered as a northern extension of the A4008 in the 1960s. It regained its original number when the new M1 link road was built with that number in the 1990s.
