Wandsworth Town Hall stands at the southern end of the former A3221
The A3221 was described in a former DfT roads list as Fairfield Street, Wandsworth.
The road started on Old York Road (the original route of the A3205) and headed south along Fairfield Street, ending about a quarter of a mile later on the A3 at the top of East Hill by Wandsworth Town Hall.
Owing to the road's short length its history is uncertain. The road was unclassified in the original 1922 allocations and it is not known exactly when it gained its number. Now, however, it is part of the Wandsworth Gyratory. The road is one-way, in the direction described, and carries eastbound A3 traffic; however, the road is labelled A217 on some maps.
