| A428 road
The A1303 is a predominantly single carriageway road running entirely in the county of Cambridgeshire, England. Prior to the construction of the Cambridge northern bypass and the Newmarket bypass, the A1303 had been classified as part of the A45.
The road currently runs from a junction with the A428 near Hardwick. The Cambridge American Cemetery and Memorial is located three miles west of Cambridge on the A1303. The road runs over the M11 motorway at junction 13 and past the Madingley Road Park and Ride site into Cambridge. It leaves Cambridge past the Airport and Newmarket Road Park and Ride site, and passes over the A14 for the first time at Stow-cum-Quy. It then passes Bottisham before passing over the A14 and A11 and ending at the July Racecourse roundabout near Newmarket.
