The B4636 runs from the B4205 by Worcester Shrub Hill railway station to the A4538, Pershore Lane, east of the city. Although the road existed in 1922 it was not classified until the 2000s.
The road starts at an unusual junction on the B4205, which could be a mini-roundabout but with the roundabout itself being painted were it not for the fact that B4636 traffic does not have to give way. This could have something to do with the fact that our road immediately goes under a single-lane railway bridge whose flow is controlled by traffic lights; B4205 traffic is unaffected by the signals. The road then passes under three further railway bridges wide enough for two-way traffic, although the final bridge now carries a road through an industrial estate following rail downgrading.
Continuing east the route follows Newtown Road for some 2.5 km out to a roundabout junction with the A4440 at the south-eastern corner of the Warndon Villages housing development. Crossing the city boundary here, the B4636 passes over the M5 and runs through countryside for a further 1.5 km or so before terminating at a roundabout on the A4538, about a kilometre south-south-east of junction 6 of the motorway.
