The A510 is a short A-road in east Northamptonshire. At under 7½ miles long this must be one of the briefest three-number ‘A’ road journeys in the area.
Wellingborough - Cranford St John
The road's original route ran from the then-A45 in Wellingborough town centre to what was at the time the A604, via a crossing of the A6 at Finedon.
Descending into Wellingborough
Little has changed. The road now begins to the at the northern edge of Wellingborough at a junction with the A509 (itself routed west of the town) and the Harrowden Road (the old A509, now A5193, going back into town). The A510 is for the first mile or so a ring road/relief road/link across to the old road just west of the railway line, where it makes a sharp left turn over the tracks and away towards Finedon two miles further on. Here it crosses the A6 in the middle of the village and carries on over the wolds to near Cranford St John. At this point the A510 terminates on the modern A14 dual carriageway at the dumbbell J11.
