Changed traffic conditions on M4 Motorway near Reservoir road

24 April 2018

Motorists are advised of changed traffic conditions from next Monday on the westbound Reservoir Road entry ramp on to the M4 Motorway at Prospect.

A Roads and Maritime Services spokesperson said ramp widening work is being carried out as part of the $470 million M4 Smart Motorway project which aims to reduce stop-start traffic, improve travel times and provide a smoother journey for motorists.

“Roads and Maritime is continuing to deliver this future-proofing project, with crews now getting ready to start work on the westbound Reservoir Road entry ramp,” the spokesperson said.

“As part of Stage 2, work on the entry ramp will include installing temporary barriers and signs, earthwork and drainage work, road resurfacing, line marking as well as installing permanent signs and guardrails.

“Crews will also be on site to install bridge girders and pour a concrete deck which will form part of the widened entry ramp.”

The spokesperson said work will be carried out between Monday 30 April and Wednesday 17 October for six days a week, excluding public holidays and weather permitting.

Work will be carried out for up to 140 shifts between 7am and 6pm on weekdays and between 8am and 1pm on Saturdays.

To minimise the impact to motorists, six shifts of night work will be carried out from 6pm to 7am Sunday to Friday.

“While work is carried out, the speed limit along the M4 Motorway will be reduced to 80 km/h between the Reservoir Road interchange and Roper Road interchange in both directions,” the spokesperson said.

“Cyclists will also be temporarily detoured via the Great Western Highway while ramp widening work is carried out.

“The work may generate some noise but every effort will be made to minimise impact to the community.”

Roads and Maritime will continue to work with the community and thanks it for its patience while work is carried out.
