A $75m upgrade of the Heysen Tunnels is expected to start in the first half of next year and be completed in late 2023 after a tender was released to the market.
The project will include lighting and ventilation upgrades, a new fire suppression and traffic management system, upgraded over-height vehicle detection systems and better communication with the Traffic Management Centre.
