Motorists on the M6 in the West Midlands are benefitting from new signs and signals between Junction 4 (Coleshill) and 5 (Castle Bromwich) as new variable speed limits are introduced to tackle congestion. As part of the Birmingham Box Managed Motorways 1&2 project, the variable speed limits will operate at peak times to tackle congestion and improve safety for road users. This is the first time this technology has been used on the M6 and follows on from its successful use on the M42 and the M25. The variable speed limits will be mandatory. The managed motorway system allows the Highways Agency to smooth out traffic flows during congestion and to close lanes following an incident to reduce the risk of further collisions.
