The Newmarket Road site is situated to the east of Cambridge. Exit the A14 at the junction marked towards Stow-cum-Quy and Cambridge. At the end of the slip road is a roundabout. After the roundabout, the Park & Ride is the first turning on the right. Newmarket Road is ideally situated if you are coming in from the A14 westbound.
