The M38 (A) motorway (English for, highway M38 (A) '), also known as Aston Expressway known, is a short motorway in Birmingham, England. He is just two miles (3.2 km) long; construction began in 1969 and was released on May 24, 1972 together with the then last section of the M6 . The expressway is very unusual in its execution, as it has across much of seven lanes without median strip, the use of which can be controlled through dynamic traffic guidance systems. This short motorway forms part of the extended A- road A38.
Many houses from the 19th and 20th centuries in Aston were demolished to create space for the highway.
Course
The highway begins as a continuation of the A roads A38 and A5127 and immediately passed the Gravelly Hill Interchange, a spaghetti - node with the M6 motorway. After the node of siebenspurige section starts on a viaduct through the district of Aston, taking a portion of the property of the Castle Aston Hall a. After a mile road reaches the first connection point, which can be used only to and from M6. Then she runs into a ditch before it with the inner ring road of Birmingham, where the siebenspurige section and in the height of the junction, the highway ends the second junction.
The viaduct in Aston was built in a curve to avoid the site of Ansell's brewery, but was demolished before completion. About the freeway was also a vinegar - piping between the two parts of the now-defunct HP sauce factory.
Dynamic traffic management
The motorway A38 (M ) was the first road in the United Kingdom with dynamic traffic management. In the central part with seven undivided lanes (without emergency lanes ) of traffic over dynamic traffic signpost is passed; one lane between the two directions is always locked for security reasons. For the morning rush hour four lanes into town and two lanes are released out of town, in the early evening rush hour, the ratio is reversed, and at all other times three lanes are released for each direction. Because of this traffic management, the speed is always limited to 50 mph (80 km / h).
Motorcycles may not travel in the middle ( red ) track regardless of the current traffic routing, under which runs a drainage line. This scheme was introduced after a fatal accident, which was caused by a dissolved manhole covers.
