|Route outline (key)|
The B4100 runs through central Birmingham and, like its current namesake in north Oxfordshire and south-east Warwickshire, consists of downgraded former sections of the A41. The route number is not signed at either end point and only very sparsely intermediately, with "A41" still being displayed at one or two points.
Starting from the A4540 at Camp Hill Circus the road runs along Camp Hill, High Street Bordesley, High Street Deritend and High Street Digbeth, then around the Moat Lane/Digbeth gyratory. In the city centre it follows the section of Park Street up to Moor Street, then Moor Street Queensway up to the Chapel Street/Jennens Road traffic lights, where it meets the B4114. This last section is one-way only.
There is then a discontinuity, and the B4100 reappears at the Snow Hill interchange on the A38 Queensway. Heading northwest it takes in Old Snow Hill, Constitution Hill, Great Hampton Street and the Hockley Flyover. It then merges into the A41, which springs back into life to head through Handsworth towards West Bromwich.
