The A4201 starts at Piccadilly Circus and heads north along Regent Street. It passes BBC Broadcasting House before travelling along Portland Place to form both branches of Park Crescent.
In 1922, the A4201 only went as far as Oxford Street - most of the road north of there was the B505, although that went along Great Portland Street rather than Portland Place so did not have to zigzag across the A501.
