Doonella Lake Bridge Upgrade

Building a Safer, Stronger Connection

Council contractors will soon begin upgrade works on the Doonella Lake Bridge in Tewantin.

Originally built in 1968, the bridge is a key link between Tewantin and Noosaville, carrying more than 20,000 vehicles each day as well as many pedestrians and cyclists. This upgrade will extend the bridge’s lifespan by around 50 years and ensure it meets modern safety and design standards.

Scope of works

The Doonella Lake Bridge Upgrade will include:

  • Replacing and upgrading existing bridge and road approach barrier rails
  • Investigating options to widen the bridge for better cyclist access, including the relocation of essential services
  • Strengthening of the existing bridge structure to meet new bridge design standards and support future transport needs.
  • Improving the Bridges Road approach (at Hilton Terrace) for a more comfortable rider experience
  • Reducing ongoing maintenance and operational costs through major capital remediation works. This includes the repair and encasement of all existing bridge piles.

Project timeline

Construction is expected to commence in February 2026 and take approximately eight months to complete, weather and site conditions permitting.

Traffic impacts

To safely carry out the upgrade works, temporary changes to traffic conditions will be in place throughout construction. Variable Message Signs (VMS) will be installed to keep road users informed of changing conditions, and emergency services will be kept updated for the duration of the project.

Marine impacts

For safety reasons, marine access under the bridge will be closed while works are underway. Waterway users are advised to plan alternative routes during this period.

Noise impacts

Construction noise is expected during the upgrade works. Council and the project team will make every effort to minimise disruptions and thank the community for their patience and understanding.

Nightworks

To help minimise disruption during peak periods, some works may be undertaken at night where feasibility practical.

Funding

This project is proudly funded by the Australian Government’s Bridge Renewal Program, in partnership with Noosa Council.

Council appreciates the community’s patience and cooperation as we deliver this important infrastructure upgrade to ensure a safer, stronger connection for years to come.
