"The A509 is a short A-class road (around 30 miles (48 km) long) for north-south journeys in south central England, forming the route from Kettering in Northamptonshire to the M1 and A5 in Milton Keynes. From north to south, the road begins at Wicksteed Park in the outskirts of Kettering. It then crosses the A14 (where it becomes a primary route) and goes through Isham and Great Harrowden."@en .
