The A2025 is an urban 'A' road through the Sussex village of Lancing.
The road starts at a roundabout with the A27 in North Lancing. It then heads south down Grinstead Lane, mainly past houses and signs for Lancing village centre. It then crosses the railway line on a bridge before the former B2222 joins from the right at a T-junction, where the road becomes South Street. It then used to multiplex with the B2222 past a scout hall and the Lancing Methodist church before the B2222 left down Penhill Road.
The A2025 then passes the local church and the parish halls before meeting the A259 at a mini-roundabout.
Perhaps unusually for an urban 'A' road, the A2025 has no traffic-light-controlled junctions or roundabouts other than at its start and end, just some pedestrian crossings. Expect large queues far down Grinstead Lane to get onto the A27 at rush hour.
The A2025 was originally unclassified but gained the B2125 number in the mid-1920s. This lasted under 10 years before it was upgraded to become the A2025. The road was rerouted in the middle of the 20th century to avoid Lancing village centre and the level crossing.
