The A1235 is a link road to the north of the Essex New Town of Basildon.
The road starts at a roundabout on the corner of Gloucester Park, where it meets the A176 running north from the town centre. The A1235 heads east along the D2 Upper Crane Road, initially running between the park and an industrial estate. Several roundabouts are crossed en route.
After the park ends there is a housing estate off to the right of the road and it is not long before the end of the industrial estate is reached and the road appears rural. However, another industrial estate is soon reached, although the houses to the right are still some distance off behind an expanse of grass. The road ends at a further roundabout where it meets the A132.
