The A6003 links Kettering and Corby in Northamptonshire, with Oakham in Rutland, via Leicestershire.

The road starts at junction 10 of the A14, heading past Wicksteed Park and into Kettering.

The stretch between the A43 and the A6014 road in Corby is the only length of dual carriageway on the route.

A bypass has been constructed from Barford Bridge on the A6003 to the A43 west of Stanion to relieve the traffic on the single carriageway passing through Geddington on the A43.

North of here it passes Rutland Water before arriving at Oakham, where a new bypass has been constructed.
