(former A648) near Barton-in-Fabis
The A648 was the original number of the road on the right bank of the River Trent from the M1 to Nottingham.
The road started at M1 J24; this interchange was originally only with the A6 but the A648 was built to it in 1969. It then headed northeastwards along wholly new-build road until it reached Clifton, where it joined the route of the B679 (which took a more roundabout route to join the A6 in Kegworth village; this was declassified when the A648 was built).
The A648 continued along the ex-B679, crossing the A614 (now A52) Nottingham bypass before ending in West Bridgford, where it met the A60 and A606.
In 1978 the A648 number became redundant. The part of the road to the west of the A614 was renumbered as part of a rerouted A453; the section to the east regained the B679 number.
