State Square Underground Car Park

State Square Underground Car Park is an NT Government Project.

Current Works

  • The pedestrian footpath on the Herbert and Mitchell Street sides of the State Square Underground Car Park site will be closed until further notice from Monday 21 January 2019.
  • Traffic and pedestrian access on Parliament Lane will be diverted through the Parliament House Car Park on the following dates and times:
    • Monday 18 February - 7:00 am - 11:00 am
    • Wednesday 20 February - 5:30 am - 5:00 pm
    • Saturday 23 February - 5:30 am - 5:00 pm

State Square underground car park aims to relocate all of the existing surface car parks underground, to allow further development of the State Square precinct, free up green space and reduce heat. The facility will house 450 car parks including public parking and have a dual role as a Cyclone Shelter with the ability to shelter 600 people.

By moving the existing car parking underground, more space will be created within the State Square precinct for landscaping, walkways, cycle paths, shade, cooling water features and relaxing/social areas.

The Northern Territory Government is committed to transforming Darwin’s CBD into a tropical, world-renowned destination, boosting tourism and enhancing Darwin’s liveability.

Construction of the car park is expected to commence in June and will take approximately 16 months to complete.

The Northern Territory Government is committed to revitalising the CBD, and will continue to work with the Australian Government on the Darwin City Deals.

Current Works

  • The pedestrian footpath on the Herbert and Mitchell Street sides of the State Square Underground Car Park site will be closed until further notice from Monday 21 January 2019.
  • The footpath is located within the boundary of works and land that needs to be excavated for construction to progress and for safety reasons access must be restricted.

    • Monday 18 February - 7:00 am - 11:00 am
    • Wednesday 20 February - 5:30 am - 5:00 pm
    • Saturday 23 February - 5:30 am - 5:00 pm

Access to Parliament House, Supreme Court and State Square Precinct and the car parks in the area will not be affected.

Vehicle access to Parliament House will be though the Parliament Gate House and remain unchanged.


Excavation works for the construction of the new underground car park at State Square in Darwin’s CBD will start on Wednesday 29 August.

The following will be implemented during excavations:

  • Traffic management and control will be in place for when material is hauled off site
  • Fence hoarding will be erected around the site for safety and security
  • Dust and debris mitigation measures will be taken during excavations and construction

Truck movements will be ongoing between 8.30am and 4pm from Monday to Friday, and between 7am and 5pm on weekends.
