|Route outline (key)|
The B4138 is a fairly long urban B-road in the West Midlands.
The route starts at Little Aston crossroads, right on the edge of the urban area, and heads south, into the city. To start with it follows the boundary of the city of Birmingham and also the route of Ryknild Street.
The B4138 then heads south along Rosemary Hill Road. It soon crosses the A454 at traffic lights and then reaches Streetly. It meets the B4151 at a roundabout on the edge of Sutton Park before following the edge of the park for over a mile. Eventually the road bears right to reach a roundabout where it meets the A452 and A4041. Here it leaves the city boundary but not the Roman road.
There is a short multiplex south along the A452 before the B4138 turns right and regains its number and direction (as if it had not detoured to meet the roundabout). However, this is the original northern end of the B4138; it was extended north past Sutton Park in the mid-1920s. It heads into Kingstanding along Sutton Oak Road and soon becomes dual carriageway. The road remains D2 for well over a mile to its southern end on the A453 at Perry, only a short distance from the M6 (although there is no junction here).
