The B4637 is a short road to the east of Worcester City Centre.
The road starts at traffic lights on the B4205 just east of its bridge over the Worcester & Birmingham Canal. It heads east past light industry in the former GWR engine works before going through a tunnel under the railway line just north of Shrub Hill station. After a second railway bridge, now carrying a road through an industrial estate, we climb into a residential area. We follow Tolladine Road through the suburb of Tolladine before ending at a roundabout on the B4638 on the edge of Woodgreen.
