Hampshire County Council appointed Colas to undertake works to relieve congestion at busy times and improve safety at the four arm mini roundabout at Harts Farm Way, Southmoor Lane, Brockhampton Road and Brookside Road.

Works completed.


Scheme overview

Congestion is experienced during the morning peak period on the Brockhampton Road approach, which often extends into Solent Road. Congestion is also experienced in the evening peak, with queues extending along Southmoor Lane and back to Penner Road and the Scottish & Southern Electric offices. This scheme is intended to replace the existing mini roundabout with a larger full roundabout to increase traffic flow and discourage excessive speed through the junction.

Hampshire County Council is working with Havant Borough Council to deliver this scheme.

Scheme Design
The scheme involves the introduction of a kerbed central island and kerbed islands on all approaches to the roundabout. Revised footway alignments on the approaches are intended to deflect vehicles from driving along a straight path through the roundabout or undercutting the roundabout. There will be angled entries to control speed at the roundabout for all arms. The existing mini roundabout will be replaced with a physical kerbed roundabout to ensure drivers take the appropriate route on the roundabout using the correct circulatory behaviour.

Moving the kerb line back into the eastern verge of Southmoor lane, and providing two northbound lanes on Southmoor lane, will provide greater capacity at the junction, which will reduce congestion.

A new pedestrian refuge on Brookside road, and additional on and off-road cycle facilities on the Brookside road approach to improve the existing east-west cycle route (NCN2) through the junction, will result in safer pedestrian and cycling facilities at the roundabout junction.

The scheme will involve resurfacing the road due to the existing poor condition.
