The A38(M), also known as the ASTON EXPRESSWAY, is a motorway in
It is extremely unusual among UK motorways, as part of it consists of seven lanes with no central reservation, and operates a tidal flow system in an attempt to minimise congestion. Due to the nature of the road, the speed limit is reduced to 50 mph (80 km/h) for most of its length with a very short length of 30 mph (48 km/h), though there are no permanent speed cameras .
When construction work of the motorway began in the late 1960s, many

A38(M) runs from the A5127 through
Gravelly Hill Interchange where
the A38 joins and then shortly after traffic from the
M6 motorway also
joins. It then enters a tidal flow section. The road is on a viaduct
as it passes through
The Expressway was the first road in the United Kingdom to introduce
tidal flow to allow better management of traffic. Lane use is
controlled by means of electronic overhead signs, with one lane always
closed to create a buffer between the two directions of travel –
there is no central reservation . In the morning, four of the seven
lanes are designated for use by traffic heading toward
Motorcycles are banned from the red-surfaced central lane, which contains a drainage channel, regardless of how it is being used. This follows a fatal accident which occurred when one of the drainage covers dislodged.
