Works on the next phase of improvements to the A23 Streatham Hill are starting later this month.

Overnight closures and one lane in each direction will be in place from 29 June until August, so journeys are expected to take longer.

The work will add safer crossings, protected cycle lanes and bus lanes to improve safety and traffic flow.

The scheme is part of longer-term upgrades running into 2027 to make the road safer after a high number of crashes and injuries.
