The M42 motorway is a major road in England. The motorway runs north east from Bromsgrove in Worcestershire to just south west of Ashby-de-la-Zouch in Leicestershire, passing Redditch, Solihull, the National Exhibition Centre (NEC) and Tamworth on the way. The section between the M40 and M6 road forms part of the unsigned Euroroute E05.

After Tamworth the road is downgraded to dual-carriageway status as the A42 road. The junctions on this section, 12-14, are numbered as a continuation of the motorway.

The section of the M42 between junctions 7A and 9 was re-built as part of the M6 Toll works and now forms the link between the M6 and the southern end of the toll road.

Along with sections of the M5 and M6, the southern sections of the M42 form an orbital motorway around Birmingham. Much like the M25 around London, there are areas where this orbital system does not work well. One such point is junction 3A, the link between the M42 and the M40, where traffic is often heavy in the rush hour.

Junction 6 for Birmingham International Airport and the National Exhibition Centre (NEC) can also be problem area when major events such as Crufts are taking place at the NEC.

When the M42 was going through the planning stages in 1977 there was great opposition to the development by the residents of Bromsgrove. Ironically, much of the town's population now depends on this motorway (and the M5) for their commuting needs. Obviously many of the people attracted to the town from the 1980s onwards have come because of the motorway links.

The motorway is frequently used to test new technologies. The Highways Agency is currently implementing an Active Traffic Management (ATM) system between junction 3a and 7 of the M42. This is a new pilot motorway scheme which combines a number of new technologies with some tried and tested motorway traffic management techniques. The scheme includes mandatory variable speed limits, as on the M25, enhanced driver information signs and a new congestion and incident management system. This system allows operators to open and close any lane to traffic in order to help manage congestion or an incident. This includes using the hard shoulder as a running lane between junctions under controlled conditions.

The road also used innovative road surfaces, which were not adopted elsewhere because of the noise created. The latest scheme to be tested on a long gently climbing stretch is one in which eastbound HGVs are not allowed to overtake during daytime hours. This scheme was implemented because the route is often congested on account of the motorway having only four lanes (two lanes in each direction) as it leaves the West Midlands.
