The A217 London Road was closed in both directions from the A239 Cricket Green to the A239 Morden Road due to a police incident earlier today.
It is not known at this time whether anyone was injured in the incident.
Local authorities were hoping for a quick resolution to the incident as heavy traffic was expected later on on one of the busiest roads in Mitcham.
The road was closed around 1am this morning (Saturday, November 13) and the bus routes affected by the closure were the 118, N44 and N133.
