The B680 is a short urban B-road on the edge of Nottingham.
Originally the road started on the A52 in the city centre, at a place now lost under the Broad Marsh Centre. It headed south along Wilford Road to cross the River Trent at the Wilford Toll Bridge. The direct line of this road has largely been replaced by the Meadows estate - and the bridge was demolished in the 1970s (presumably this is when the road was declassified) and was replaced by a footbridge; this was widened in 2014 when a new tram line was built across it.
The current northern end of the B680 is at the southern end of Main Road, which still runs south from the bridge, at a set of traffic lights on the B679. The road runs south, parallel to the A52 western bypass. It bears to the left and crosses a wooded cutting, which used to carry the Grand Central Main Line, before going under the A52 and entering open country.
The road passes a golf course before entering Ruddington and runs into the village centre. In the middle of the High Street it TOTSOs left into Kirk Lane (although its original route was the parallel Easthorpe Street) to end at traffic lights on the A60.
