Gosford Bypass

The NSW Government is carrying out traffic survey investigations along the Pacific Highway, Manns Road and Showground Road corridor at Lisarow, Narara and Wyoming to provide Transport with a better understanding of current traffic volumes in the area.

Transport for NSW is carrying out surveys of the road corridor from Monday 10 March 2025, including the Pacific Highway from Parsons Road to Renwick Street, Manns Road and Narara Valley Drive from Dell Road to Pearson Street and the surrounding adjacent network. Work is expected to be completed in up to six weeks, weather permitting.

Work will be carried out at night intermittently at various locations from 7pm and 5am, Monday to Thursday.

Thank you for your patience during this important work.

Transport is progressing the development of the corridor to deliver shorter term improvements, and also to confirm the longer term strategy for future major upgrades along the corridor. 

The Gosford Bypass is a major corridor extending from the M1 Pacific Motorway at Ourimbah to the Central Coast Highway at West Gosford.

The route follows the Pacific Highway from the Ourimbah Interchange then along Manns Road at Narara through to the Central Coast Highway. Every day up to 30,000 vehicles travel along this corridor.

Gosford Bypass from the M1 Motorway, Ourimbah to Parsons Road, Lisarow in the north and from the Central Coast Highway, West Gosford to Stockyard Place in the south have been completed. The corridor has been progressively developed and constructed over the last 20 years, leaving around 7.2km of Gosford Bypass to be upgraded.

Development of the remaining 7.2km section has included community engagement at different stages, identification of the preferred road alignment for some of the route and associated property impacts. 

Historical information on stages of the Gosford Bypass that have been developed and constructed can be found below:

• Pacific Highway duplication at Lisarow
• Narara to Lisarow – Manns Road – Pacific Highway
• West Gosford to Narara – Manns Road

• Improved safety for all road users.
• Better travel times and less congestion on Pacific Highway and Manns Road.
• Safe road access points and pedestrian crossing locations along the Gosford Bypass corridor.
• High quality pedestrian and cycle infrastructure.
• Improved bus stop facilities.
• Improved freight efficiency and productivity .

Transport is progressing the development of the corridor to deliver shorter term improvements, and also to confirm the longer term strategy for future major upgrades along the corridor. 

As part of our longer-term planning, a review and assessment of the previous Gosford Bypass design will be carried out to identify staging opportunities and priorities along the corridor. 

Delivery of any future works on the remaining 7.2km section of Gosford Bypass, including any property acquisition, will be dependent on gaining project and funding approvals.

In parallel, Transport is developing accelerated shorter-term initiatives to improve road safety, traffic flow and active transport infrastructure, which will complement the longer-term upgrades.

We will keep the community updated as work progresses. We would like to thank you for your patience during this important work.
