Early work to prepare for the upgrade will soon be complete.  The final works involve shifting the safety barriers away from the road, installing utilities, changing line marking and signage.

Throughout the day, there will be ongoing work to maintain environmental controls, landscaping and vegetation management.

Thank you to those stakeholders and community members who commented on the concept design and review of environmental factors (REF) for the Central Coast Highway and Tumbi Road intersection upgrade.

We have published a submissions report summarising the community comments, our responses and details of the decision. The full submissions report (PDF, 6.74Mb) can be viewed, or you can read the June Community Notification (PDF, 204Kb).

We will keep the community updated about the progress of work.

The Central Coast Highway provides an important connection between the M1 Pacific Motorway at Kariong and the Pacific Highway at Doyalson through Gosford, Erina and The Entrance.

With around 26,000 motorists using the Central Coast Highway between Wamberal and Bateau Bay daily, the NSW Government invested in early planning for the upgrade to help ensure the highway was prepared to handle future growth. 

In June 2020, we sought feedback on the proposed strategic design and received general support for widening the highway to two lanes in each direction to improve safety and traffic flow. 

The upgrade of the most congested section, being the intersection at Central Coast Highway and Tumbi Road was prioritised and fast tracked. Early work to prepare for the intersection upgrade has now been completed.

Construction for the main works on the Tumbi Road intersection upgrade is subject to approval, as such timing is not yet confirmed but tendering is expected mid-2024.

The upgrade would:

• Reduce delays, queuing and improve traffic flow at the intersection
• Improve journey reliability and safety for all road users
• Provide more reliable public transport amenities and access
• Improve local walking and cycling connections.

The Central Coast Highway and Tumbi Road intersection upgrade would include:

• Replacing the existing intersection roundabout with traffic lights
• Widening the Central Coast Highway north of the intersection to two lanes in each direction
• Providing two right turn lanes out of Tumbi Road onto the highway southbound
• Lengthening the left turn lane into Tumbi Road from the northbound lanes of the highway
• Providing a right turn lane into Tumbi Road from the southbound lanes of the highway
• New and upgraded footpaths and shared paths
• Providing a u-turn bay in front of Pacific Garden Hotel for southbound traffic
• Providing an interim transition back to the existing arrangements at the northern limit of works, near Forresters Beach Garden Centre
• Relocating two existing bus stops to a common location northbound on the Central Coast Highway north of the intersection.

Construction for the main works on the Tumbi Road intersection upgrade is subject to approval, as such timing is not yet confirmed but tendering is expected mid-2024. The project will take about two years to complete.

We will keep the community updated as work progresses.
