Night works: Pacific Motorway and Gateway Motorway, Rochedale

From 1 July there will be intermittent construction activities carried out at night on the Pacific Motorway between Logan Road and Rochedale Road, from 7pm to 5am Monday to Friday, and 7pm to 7am Saturday and Sunday. Motorists can expect minor delays.

Some works will also take place on the Gateway Motorway, Rochedale and the southbound onramp. There will be a considerable increase in travel time if using this on-ramp. 

Works will include line marking, sign and barrier installation and some tree clearing.  These works take place at night when traffic volumes are lower to minimise impacts to motorway traffic.

Traffic control, including temporary lane closures will be in place. 

Seek alternative routes whenever possible.

Reduced speed limits: Pacific Motorway and Gateway Motorway, Rochedale

From 1 July 2018, the posted speed limit will be reduced to 80km/hr within the project area (please see map below for clarification on project area.)

The speed limit on local roads including Rochedale Road, Underwood Road and School Road will also be reduced during construction works.
