The B309 was a short link road in Westminster.
It started at the junction of Pall Mall and Regent Street and headed west (Pall Mall east of here was the A3213).
At the west end of Pall Mall, by St James's Palace, it turned north and headed along St James's Street. It ended on the A4 Piccadilly a short distance afterwards.
The B309 is now part of the A4 one-way system in the area. Pall Mall, for example, is now one-way westbound.
