Reference Design and Business Case
Stage 1: Coomera to Nerang
The southern section of Coomera Connector between Coomera and Nerang has been identified as the priority section that will be built first.
When constructed, Stage 1 of the Coomera Connector is anticipated to improve transport capacity and accessibility, while also reducing trips on the M1 by providing:
- an alternative north–south route between Coomera and Nerang
- additional crossings of the Coomera and Nerang rivers
- improved safety on the M1, reducing congestion by encouraging up to 60,000 vehicles per day to use the Coomera Connector for local trips
- more reliable travel times between Brisbane and the Gold Coast.
Reference design and business case
Taking feedback from the community into consideration, the Department of Transport and Main Roads (TMR) is developing a reference design for Stage 1. While the Coomera Connector corridor is wide enough for 6 lanes, predicted traffic volumes will inform the number of lanes that need to be included in the reference design.
The reference design will contain a sufficient level of detail to enable a cost estimate to be produced for the project. The estimated cost of Stage 1 will be documented in the Stage 1 business case, which is being led by Building Queensland.
The reference design and business case are expected to be completed in mid-2021 for government consideration.
Protecting our environment
The Coomera Connector will deliver best practice environmental outcomes.
Environmental approvals for the project are required through the Department of Agriculture, Water and the Environment’s assessment of the Stage 1 project under the Environment Protection and Biodiversity Conservation Act 1999.
Environmental conditions will need to be satisfied to protect Matters of National Environmental Significance located in and around the corridor including the RAMSAR wetlands at Coombabah and local koala populations at Coomera, Helensvale and Parkwood.
More information about how environmental impacts will be addressed in the planning for Stage 1 of the Coomera Connector is available on the Coomera Connector project page on the TMR website.
Stage 1 design features
Coomera Connector design features
The Coomera Connector Stage 1 reference design will include the following design features:
- The Coomera Connector will be a high-speed motorway style road
- Grade-separated (elevated) interchanges will minimise impacts on the existing traffic network
- A shared path for walking and bike riding will improve opportunities for active transport
- Bus priority measures and new bus routes will improve public transport outcomes
- Noise barriers will form part of the design to minimise impact of road traffic noise
- Wildlife sensitive design and exclusion fencing will allow safe wildlife movement.
Connecting to Coomera
Investigations are continuing to determine where the northern end point will be for Stage 1 of the Coomera Connector.
An interchange at Shipper Drive is currently under investigation as an alternative to Oakey Creek Road. An interchange at Shipper Drive would facilitate access to the Gold Coast Marine Precinct and commercial precinct near Beattie Road.
Access to Coomera would be via Shipper Drive to Foxwell Road including an upgraded intersection at Foxwell Road.
Hope Island Road investigations
The Coomera River area is highly constrained with the rail corridor and planned Helensvale North station to the west of the Coomera Connector corridor and residential properties to the east.
Investigations have concluded that it is not feasible to provide a connection to Hope Island Road due to the significant number of residential properties and businesses that would need to be acquired.
Access to the Coomera Connector for Hope Island, Sanctuary Cove and Paradise Point will be provided via the interchange at Helensvale Road.
Helensvale Road interchange
The Coomera Connector will be elevated over Helensvale Road, minimising impacts to traffic flows on Helensvale Road.
Gold Coast Highway interchange
At Helensvale the Coomera Connector will run under the Gold Coast Highway, minimising impacts to traffic flows on the Gold Coast Highway.
Smith Street Motorway interchange
At Parkwood the Coomera Connector will be elevated over the light rail park'n'ride facility, Smith Street Motorway and the light rail.
Southport-Nerang Road interchange
The Coomera Connector will be elevated over Southport-Nerang Road minimising impacts to traffic flows on Southport-Nerang Road.
Nerang-Broadbeach Road intersection
The Coomera Connector will start on Nerang-Broadbeach Road just west of Metricon Stadium providing an additional crossing over the Nerang River. Access to local businesses will be maintained.

Walking and cycling
A shared path for walking and bike riding will be included along the full length of Stage 1 of the Coomera Connector. The path will provide a safe and connected walking and bike riding network for the northern Gold Coast area, increasing the opportunity for local communities to access new options for healthy and enjoyable outdoor exercise.
