Overview

The project required the construction of a dual carriageway running the length of 1.45km from Durnin Avenue to Spearwood Avenue in the City of Cockburn. The carriageway consists of four traffic lanes with a raised central median island separating the opposing flow of traffic. On-road bicycle lanes and off-road shared paths were included to improve pedestrian and cycling safety.

​

Scope of work included the following:

• Earthworks, drainage (storm water, pits and basins)

• Roadworks, footpaths, barriers and bollards

• Street signage

• Limestone block retaining walls

• Fencing

• Underground power

• Landscaping

• On road bicycle lanes and off road shared paths

• Bus bays and shelters

• Acceleration lanes

​

Project Challenges

• Complex traffic management posed many challenges.

• Roads and lanes remained open as much as possible during construction to keep traffic flowing, however short closures of access were required.

• Pedestrian routes would be impacted

• Construction impacts such as noise and dust were controlled as much as possible.

• ​

Managing These Challenges

• Liaising with Western Power was essential to allow for the program to accommodate this and not to cause any delay to the target date of Practical Completion.

• Liaising with Brookfield and the Railway Authority was required to install the railway underpass fencing.

• Pedestrian routes were diverted for safety.
