The route starts one block inland from the coast on the A259 in Hove and heads north along Hove Street, passing to the west of the town centre. One block north the B2066 is crossed at traffic lights and we continue through the suburbs along a residential road. The road soon bends slightly to the left to go under the West Coastway Line before it crosses the A270 (former A27) at traffic lights.
Continuing north, the A2023 passes Hove Park School, then crosses a roundabout providing access to the greyhound stadium. The road bends sharply left at the next set of lights before running along Nevill Road to end on the edge of open country at a T-junction on the A2038.
The original route of the A2023
The A2023 number first came into existence before World War II as an upgrade of the B2123. This ran along The Drive to the east of Hove town centre between the A259 and the then A27.
Following the inauguration of the A2038 to form a northwest bypass of Brighton in the 1960s, it was deemed expedient to have a main road from Hove joining it. This was not possible for the original route of the A2023, so the number was moved further west, taking on the B2124 and then extended along unclassified roads to meet the A2038. The old A2023 was renumbered B2185.
