Stage 3

Project description

Complete: Gundaroo Drive duplication stage 3.

These significant road and bridge works delivered a smoother and safer road. Better connecting Gungahlin and Belconnen for all road users including cyclists.

The project was jointly funded by the Australian and ACT Governments under the Infrastructure Investment Program.
