Central Coast region

Brisbane Water Drive and Manns Road at West Gosford

Roads and Maritime Services is carrying out a major upgrade of the Central Coast Highway at the intersection of Brisbane Water Drive and Manns Road at West Gosford.

The NSW Government is providing $170 million for the upgrade, which will improve traffic flow, travel times and safety for all road users.

The project is expected to be completed in late 2016, weather permitting.


The Central Coast Highway is a major road link between the M1 Pacific Motorway (formerly the F3 Freeway) and Gosford, Erina and the coastal suburbs.

Brisbane Water Drive and Manns Road are important links between Gosford, Woy Woy and Narara providing access to railway stations, local businesses and retail centres, the Central Coast Highway and the M1 Pacific Motorway.

The upgrade will improve traffic flow and safety and accommodate traffic growth for at least the next 20 years.

About the project

The upgrade involves widening and realigning Brisbane Water Drive and Manns Road on the Central Coast Highway to form a single intersection with traffic lights.

A new link road will be built between Corumbene Road and Grieve Close which will pass under the Central Coast Highway and Debenham Road South to connect Jusfrute Drive and Henry Kendall Street with Manns Road.

Traffic lights will be installed at the Manns Road/Grieve Close intersection, with connection to a new service road on the east side of Manns Road.

What's happening now?

Major construction activities started in November 2013 after the contract was awarded to Seymour Whyte Constructions.

There is a wide range of construction activities underway across the entire project.
