The M42 motorway (English for, highway M42 ' ) is a 40 -mile motorway in England that forms the southern and eastern part of the ring road around Birmingham and continues towards Nottingham and the M1 motorway. However, it ends too soon between Tamworth and Ashby -de- la- Zouch at junction 11 and the remaining 15 miles to the M1 are labeled as A42. The section between the M40 and the M6 is part of the not signposted in the UK E 05
The first section was opened in 1976 and joined the M6 motorway with the Birmingham and Solihull airport. In the 1980s, it extended the motorway in both directions: from 1985 to Tamworth, and AS 3 in Redditch, 1986 to Appleby Magna (now AS 11) and Catshill (AS 1), then in 1987 the piece was followed by the M5 (1987 south running roads at the local node, 1989, the northern ). The part between Appleby Magna and the M1 was never built; Instead, they built a four-lane continuation of the A- road A42, but continues the junction numbering of the M42. This differs from the original route; the current A42 runs directly to East Midlands Airport, while the west planned motorway was planned more directly to Nottingham. At the north end there is next to the end on the M1 also a node with the never -built motorway M64 between Castle Donington (M1) and Stoke -on-Trent (M6 ), now largely replaced by the A50.
Since 2005 is used on the section between junctions 3A and 7, a traffic control system, which means in English Active Traffic Management, abbreviation ATM. With the help of sensors and CCTV cameras traffic control systems can reduce peak times the speed limit and release the emergency lanes for traffic, similar to the A8 or A99 near Munich. The system was chosen as a less costly alternative to the full spread and used in this section as the first in the UK to lead the long-distance, local and feeder services to Birmingham Airport and the Exhibition Centre NEC at peak times better.
After the successful trial end in 2007 announced plans to apply this system to other polluted highways.
