A major road improvement scheme at the Prince William Road/ Ballymacash Road junction in Lisburn will commence on Monday 17 July 2023.
The improvement work, which will be carried out by developers following planning permission for residential development in the area, includes the widening of the Prince William Road , extension of the existing underpass at the location and provision of a new traffic signal junction at Ballymacash Road including the provision of PUFFIN controlled pedestrian crossings within the junction layout. The scheme will take approximately nine months to fully complete.
Given the busy nature of Prince William Road, to construct the scheme safely it will be necessary to close the Prince William Road Northbound from Knockmore Road to Nettlehill Road from 17 July for six weeks. A diversion for traffic will be in place via the Antrim Road, Pond Park Road and Derriaghy Road.
Ballymacash Road (west ) will also close for two weeks and Ballymacash (east) into Lisburn will close for up to six months from the 17 July.
From September the Prince William Road will revert to two-way traffic with the remainder of the works completed with a mixture of two-way traffic and off peak lane closures.
A temporary 30mph speed limit will also be in force during construction of the scheme.
Further road closures will be required towards the end of the scheme for surfacing of the junction, however these will be planned to minimise the effect on traffic.
Whilst the Department has carefully planned these works and associated traffic management with the contractor in order to minimise inconvenience to the public, road users should expect some delays and allow additional time when planning a journey.
Road users are asked to comply with the temporary traffic restrictions and to drive with care when travelling through the works. Pedestrian access will be maintained at all times.
