Milton Street & Archibald Street Intersection Upgrade


Mackay Regional Council

Project value



December 2021


Mackay, Qld



The previous T-intersection was  reaching capacity and the new roundabout will be able to cater for higher volumes of traffic as well as improving road safety. The construction of the roundabout at the Milton and Archibald streets intersection will also be complimented with new trunk drainage infrastructure to improve flood immunity in the area.

MRC required the construction of a single lane roundabout at the Milton Street and Archibald Street Intersection. The scope of works for the project included the construction of the roundabout and associated works, relocation of underground services, water main relocation and new trunk drainage infrastructure.

Initially, crews started the drainage installation works in the road reserve on Milton Street, followed by Archibald Street and then the roundabout installation roadworks.

What we delivered

Tree removal

  • Removal of 12 trees from the area has been completed with appropriate environmental flora and fauna controls and with relevant permit approvals.

Service relocations

  • Significant service infrastructure existed within the Milton Street and Archibald Street Road reserves. Bellwether completed service relocations between October 2020 and March 2021 to make way for the roundabout. Works were completed with weather permitting considerations during the wet season in tropical north QLD.
  • This included the relocation of optic fibre services, water mains, sewer services and electrical services.

Construction of roundabout and drainage infrastructure

“This project is proudly funded by the Queensland Government through the Transport Infrastructure Development Scheme (TIDS) and council.”

Key outcomes

This project involved traffic changes in place for eight weeks. Archibald Street was temporarily closed between Webster Street and Milton Street, including the intersection. Residents living in this area had access to their property during this time.

North and southbound traffic travelling on Milton Street accessed Archibald Street via the Archibald Service Road.

Traffic travelling east along Archibald Street was detoured onto Webster Street and Clements Street to access Milton Street.

There were some noise and dust disturbances as expected due to the various plant and equipment on site however appropriate controls were in place to minimise impact.
