A237 Mitcham Common - Coulsdon

The A237 is a north-south route in south London.

The road starts on Mitcham Common at a roundabout with the A236. It continues south along Carshalton Road across the common for about half a mile to where the A239 joins it at a T junction and then continues across a wide railway bridge at Mitcham Junction Station; the road crosses both the Tramlink and the Sutton loop line here. It continues through the common in a seemingly semi-rural area and then across Goat Green before housing at Beddington Corner is reached. The road continues onto Hackbridge where there is a T junction with extensive zebra crossing facilities at the B277 Hackbridge Road, before crossing the railway line again at Hackbridge Station on a recently rebuilt wide bridge. Then the A237 continues past Beddington Park on the left before passing a small lake, where there is a tiny section of dual carriageway, and bending sharply left into Manor Road and arriving at a traffic light junction with the A232.

From the A232 the A237 forms the main shopping street of Wallington, split in two by a dive-under railway bridge at Wallington Station, then up the hill past the Crown Court on the right to the B271 traffic lights.

From there the road continues past a development of private flats before reaching smallholdings on the right and becoming semi rural again. After here the A2022 mini roundabout is reached and then the A237 passes through Woodcote. A fork in the road marks the junction of the B2030.

A237 Junction with A2022

The A237 then continues down a steep hill, over another narrow railway bridge and down to a 5-way junction with traffic lights where it meets the B2032. From there the A237 continues past a car park on the right. The line of trees at the back of the car park marks the embankment of the ancient horse tramway from Croydon to Merstham.

The road continues to a traffic light T Junction. This used to be the end of the A237, where it joined the A23. However, since the Coulsdon Relief Road was opened in December 2006, the A23 now follows the Relief Road instead. The A237 now continues past this junction, to a roundabout from where north-facing slip roads join the A23. The A237 continues on under the A23 and a railway line to run parallel to both (and a second railway line) before going back under the railway line to end at an at-grade roundabout on the A23, at the end of the relief road.
