The A2037 is a pleasant saunter through the Adur Valley in Sussex. Originally numbered B2137, it gained its present number in 1934.
The route starts on Henfield High Street at a mini roundabout with the A281. It climbs out of the village and heads in a southerly direction towards Small Dole. It winds through the village and past the local landfill site before skirting the edge of the South Downs along the Adur valley.
The road makes a sharp right into the village of Upper Beeding where it reaches a mini-roundabout. This was the original southern end of the road at a junction with the A283 - but that road now bypasses the village to the south so the A2037 turns left here to run out of town to end at a roundabout on the A283 Steyning Bypass.
