M27 junction improvements to be carried out

Siemens has been selected to supply and install traffic signals and controllers for two major junction improvement schemes.

The orders have been placed by civil contractors Interserve Construction Limited and Jackson Civil Engineering Limited to help alleviate the flow of traffic joining and leaving the busy M27 motorway in Hampshire at junction 3 near Southampton and junction 5 near Southampton Airport and Eastleigh.

The upgrade work which is already underway is funded by the government’s £317 million pinch point programme on motorways and major trunk roads for delivery by Spring 2015.

The improvements at both junctions will see additional lanes added on some approach roads and sections of the roundabouts, as well as new traffic signals installed to increase capacity. Work is due to be completed by Spring 2015.

At junction 3, the north section of the roundabout is being signalised and existing signals on the westbound exit slip road will be replaced and additional lanes added. All sections of the roundabout will be linked to Urban Traffic Control (UTC).

At junction 5, the northeast and northwest sections of the roundabout are being signalised. Existing signals on the eastbound exit slip road are being replaced and additional lanes added. All sections of the roundabout will also be linked to UTC.

The additional capacity on these two busy junctions will allow the roundabouts to work more efficiently to reduce congestion and improve journey times.
