|Route outline (key)|
The B4170 is an urban B-road in the Black Country.
Originally it started on the A457 Birmingham Street in Oldbury. However, that road now bypasses the town to the south and so the B4170 starts on the bypass. It heads south along Seven Stars Road and soon goes under the M5.
After reaching a T-junction where it TOTSOs left, the B4170 enters Langley. Here there is a bizarre one-way system. Southbound traffic reaches a gyratory, where it meets the B4182, before continuing to a crossroads where it TOTSOs left. Turn right here to follow the northbound route, which goes along Old Park Lane on the edge of the suburb, avoiding the B4182 completely, before reaching a T-junction where it TOTSOs left on rejoining traffic from the other direction.
The one-way system does not even avoid the centre of Langley. The B4170 heads east along Broad Street before bending to the right (the now closed road to the left is the original 1922 route) and going along the High Street. At the far end, the Titford Canal is crossed before the road bends to the left, goes under the Birmingham to Stourbridge railway line and ends at a T-junction on the B4169.
