A508 ROAD

The 'A508' is a short (about 30 miles/50 km) A-class road for north/south journeys in south central England, forming the route from Market Harborough in Leicestershire, via Northampton, to north-west Milton Keynes.
The road begins in the centre of Market Harborough and crosses into Northamptonshire just outside the town. Crossing the A14 at Kelmarsh, it continues on through the centre of Northampton.
From there, it merges briefly with the A45 until it crosses the M1 at junction 15. Resuming its identity, it continues through Roade and rural south Northamptonshire, reaching the A5 at Old Stratford just outside Milton Keynes.
Between Market Harborough and Northampton, travelling south, there are two fixed (Gatso) speed cameras. The first is on top of the A14 junction (40mph limit) and the second is approx half a mile from the village of Lamport (60mph limit). Both of these cameras are rotated, meaning that they face the opposite direction of travel every so often.
