Not only does this road have the honour of starting at the magnificent Spaghetti Junction, it is also probably the most unique and bizarre motorways anywhere. It has seven undivided lanes that are controlled by overhead signal gantries. Most of the time there are three lanes each way, but at peak hours the balance is tipped 4-2, always using one empty lane as a buffer. Apparently there has never been a fatal head-on accident on this road (ie, no fatality has been caused by the lack of a central reservation), which is a tribute to the responsibility of those who use it. Nonetheless, motorcycles are now banned from the central lane because it contains a narrow drainage channel, and prior to the ban a fatality resulted from the covers of this channel working loose.
Motorways are crossed, over and under, by all manner of things - roads, railways, footbridges, water and gas mains, electricity lines and so on. But the A38(M) has a claim to fame that is probably unique in this country, if not the world. Where the road is in a deep cutting, the motorway bisects a factory compound owned by HP, they of the brown table sauce fame. The result of this is that, connecting the two sides of the production line and passing over seven lanes of the Aston Expressway, there is a vinegar pipeline.

Leaving Birmingham, the A38(M) begins life in this underpass as a good old fashioned urban motorway, in a dingy concrete trench with some steep slopes along the way.

But further out is where things start to look special. Here the traffic from the midway junction is merging in, and above us is one of the many signal gantries.
