The A1101 is the lowest road in Great Britain; along its 53 miles (85 km) approx. stretch it rarely rises above sea level. The road runs from Bury St. Edmunds north west to Littleport where it disappears for approximately 2 miles (3.2 km), it then re-appears on the other side of the A10 heading north through Wisbech and to its end at the A17 in Long Sutton. The A1101's route takes it across the Fens in Lincolnshire and Norfolk, a famously low-lying area to Suffolk through Cambridgeshire. It is the main road for access between Lincolnshire and the Fenlands. The stretch between Wisbech and Long Sutton was previously designated the A150.
