|Route outline (key)|
The B523 was a relatively short B-road in central London. Originally unclassified it is assumed that it gained its number in one of the early waves of classification of new roads in the late 1920s.
The road started on the A5204 on the corner of Portman Square and headed north along the western side of the square then continued along Gloucester Place. Presently the road crossed the A501 Marylebone Road before passing Dorset Square and ending on the A41 Park Road near the western edge of Regents Park.
In more recent years the B523 has been taken over as the northbound route of the A41, with the original route of that road now being southbound only.
