|Route outline (key)|
The B3021 is a short B-road to the east of Windsor.
It starts on the A328 on the southern edge of Old Windsor and heads north. It quickly meets Ouseley Road, a spur of itself heading to the A308, before it heads round the western edge of Old Windsor. It bends right before meeting the A308 again.
The B3021 multiplexes north along the A308 for a short distance before regaining its number at a roundabout. It skirts Windsor Home Park and crosses the River Thames at Albert Bridge. It tuns along the bank of the river into Datchet where it ends on the A470 where that road has to TOTSO.
In the 1920s the section north of the A308 was renumbered A3063 and then became an extension of the A328 in 1935. This situation existed until the 1980s when the road was given its original number back.
