Main construction works have begun today on the William Hovell Drive duplication, with the major project set to improve safety, ease congestion and support growth in Canberra's northwestern suburbs.
The upgrade will duplicate 4.5 kilometres of road between John Gorton Drive and Drake Brockman Drive, creating two lanes in each direction to ease congestion and improve safety for more than 20,000 vehicles that who use the corridor each day.
The $107.25 million project is jointly funded by the Australian and ACT governments.
The start of main works follows completion of surveying, dilapidation assessments and site compound establishment over the last month.
Long-term modelling indicates that Belconnen's population could exceed 185,000 people by 2065, and up to another 79,000 residents living in the Molonglo Valley, increasing demand for safer and more efficient transport.
Complementing the $225 million joint investment to build a new bridge crossing over the Molonglo River, which is expected to open to traffic later this year, these projects will support future housing growth in Ginninderry, Denman Prospect, Whitlam and Molonglo.
The project will also deliver a new signalised intersection, a new three-metre-wide asphalt shared path for walking and cycling, improved access to the underpass and Old Weetangera Cemetery, and incorporate environmental protections through retaining walls and dedicated wildlife crossings.
To enable construction works to proceed safely, there will be overnight closures of William Hovell Drive between Drake Brockman Drive and John Gorton Drive (both directions) from 8pm each evening starting Monday 25 May to 6am each morning until Saturday 30 May 2026, weather permitting.
Travel updates, detour maps and construction alerts will be available on the Built for CBR website, with the ACT Government continuing to work closely with the community to provide timely information and support throughout construction.
Construction is expected to take approximately three years.
