Work drives forward on M4 smart motorway project

6 April 2018

Work to improve the M4 Motorway between Mays Hill and Lapstone is progressing well with work powering ahead on the first stage of improvements.

A Roads and Maritime Services spokesperson said the first stage of work is being delivered as part of the NSW Government’s $470 million M4 Smart Motorway project which aims to reduce stop-start traffic, improve travel times and provide a smoother journey for motorists.

“Crews started work on this game-changing project last December to build an additional lane in each direction between Roper Road and the M7 Motorway, upgrade a number of interchanges and install intelligent transport systems,” the spokesperson said.

“Work has been carried out to set up a site compound, relocate intelligent transport systems and utility services, install safety barriers, install project signs and remove vegetation along the project corridor.

“In the next three months, work will be carried out to widen and lengthen the eastbound Roper Road entry ramp at Colyton, excavate a number of maintenance bays, install new fibre optic cables along the project corridor as well as install temporary safety barriers and new traffic signals on Reservoir Road at Blacktown.

“Crews will also be hard at work to widen and lengthen the westbound Wallgrove Road entry ramp at Eastern Creek as well as install cabling and in-ground sensors needed for future entry ramp meters.

“Noise walls are also on the agenda with work continuing to be carried out to complete a replacement noise wall between Grazier Place and Rutherglen Place at Minchinbury. Investigations will also be carried out for future noise walls along the project corridor.”

The spokesperson said work on Stage 1 of the M4 Smart Motorway project is expected to be complete next year, weather permitting.

Work will continue to be carried out 7am to 6pm on weekdays and 8am to 1pm on Saturdays, excluding public holidays and weather permitting.

“Motorists and the community are also advised work will be carried out to extend an existing noise wall on the M4 Motorway eastbound between Roper Road and Wallgrove Road interchanges,” the spokesperson said.

“The existing noise wall located near Rutherglen Place will be extended towards Farrington Street at Minchinbury with work due to start on Wednesday 4 April.

“Work will be carried out during standard work hours until Monday 28 May and is expected to take around 46 shifts to complete.”

Motorists are advised to drive to the conditions and follow the direction of signs and traffic control.

Roads and Maritime Services thanks the community for its patience while work is carried out.
