Alabama's maximum speed limit is 70 mph, providing drivers with a moderate speed for traveling across its diverse terrain, including coastal areas, forests, and urban centers.
Somewhere to the east of Glasgow lies the A8(M) - but look carefully, because it's not easy to find. The A8(M) is the UK's shortest motorway, running for just over 280 metres (308 yards). It forms a link between two roundabouts at Baillieston Interchange, better known as the junction between the M8 and M73.
Britain's first motorway, the Preston by-pass, opened in 1958. Designed by Lancashire County Council under civil engineer Sir James Drake – regarded as the pioneer of the UK motorway network – it's now part of the M6. The next 10 years saw UK's network expand as hundreds of miles of motorway were built.
