(former B2125) Brighton Road
The B2125 was the number given to the old A23 through the centre of Crawley when the western bypass was built. The road was renumbered as the A2219, leaving the B2125 number defunct.
Starting at the northern end of the A23 bypass in the Northgate area of town the road headed south along London Road into the town centre, where it ran along the now-bypassed High Street. There was a brief multiplex along the A264 between Ifield Road and Haslett Avenue, after which the B2125 regained its number and left town along Brighton Road. It ended on the A2004 southeastern bypass near that road's junction with the A23.
