Watford Gap

Watford Gap /ˈwɒtfərd ɡæp/ is a low-lying point between two hills, close to the village of Watford, Northamptonshire, England. Engineers from Roman times onwards have found it to be an ideal route for connecting the Midlands with South East England. In a width of 400 metres (1,300 ft) the A5 road, the West Coast Main Line railway, the M1 motorway and a branch of the Grand Union Canal all traverse the gap in parallel.
