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 NSW Government has committed $387 million to duplicating the Central Coast Highway for 3.8 kilometres between Wamberal and Bateau Bay.

Around 26,500 motorists use this section of the highway daily. By widening the highway to two lanes in both directions, the upgrade will ensure the Central Coast Highway is prepared for future growth.

As part of the project, the upgrade of the most congested intersection at Central Coast Highway and Tumbi Road has been prioritised and fast tracked.

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.

Subject to funding approval, construction of the project would be expected to start in 2023 and take about two years to complete.  We will keep the community updated as work progresses.
