Motorway M1In 1959, the first two deaths occurred on England's first motorway, the M1. It had been opened only four days earlier on 2 Nov 1959. Two lorry drivers died when they crashed into the back of vehicles halted by a minor crash. In the multiple-vehicle crash which occurred in thick fog, five persons were injured. The new superhighway without a speed limit had traffic jams in both directions for several hours. It was the first part of a planned 400-mile motorway network that was the greatest road transport improvement project since the famous straight roads the Romans built. It was a quarter-century late by international standards, but its design benefitted from knowledge gained from expressways already built in the U.S. and Europe.* |
