The B687 was a short link road in east Nottinghamshire.
The road started on the A52 Long Acre in the town of Bingham and headed north over the railway line to leave town. The road ended after less than a mile on the A46 Fosse Way.
The northernmost section of the original road was downgraded to a footpath in the 1960s when the road was rerouted onto a large roundabout where it met the A6097 as well as the A46.
The road is now unclassified and the two A-roads mentioned above have now been moved onto bypasses. The A52 bypassed Bingham in the 1980s and it is assumed that the B687 was declassified at the same time. The original line of the A46 was bypassed in 2012 but the large roundabout still exists as part of the GSJ between the A46 and A6097.
