Watford Gap

Watford Gap is a low-lying area between two hills in the English Midlands, near Daventry and the village of Watford in Northamptonshire. Engineers from Roman times onwards have found it to be an ideal route for connecting the Midlands with South East England. The A5 road, the West Coast Main Line railway, the M1 motorway and a branch of the Grand Union Canal traverse in parallel a space about 400 metres (1,300 ft) wide. It has been written and spoken of as marking the divide between Northern England and Southern England.
