Historically the town was a bottleneck on the A38 route to the South West; now traffic bypasses the town on the M5 which opened in 1962. Later in the 1970s the town received a second bypass, known as the Bromsgrove Eastern Bypass. The northern section of the route between Lickey End and Aston Fields was new construction, linking in to the A4024 which was incorporated as the southern half of the bypass.
During the reconstruction and widening of the M5 in the 80s and 90s, several improvements were made to the A38 around the town to cater for the extra traffic diverting off the motorway. This mostly included the provision of extra traffic signals at junctions and right turn refuges.
The A491 used to pass through the town centre to terminate in Finstall, however upon the completion of a link road between Fairfield and Lydiate Ash in 1963, the A491 was diverted along the new road, with the former route being renumbered as an extension of the B4091.
