MORE than three million cubic metres of fill is needed for NorthLink WA northern section, which is on schedule to be finished in 2019.
Main Roads WA said NorthLink WA northern section contractor CPB Contractors was in the process of negotiating with a number of suppliers who will start delivering before the end of the year.
Earlier this month contractors were at the Maralla Rd end of the northern section fencing off the land cleared to make way for the new highway.
A Main Roads WA spokesman said bridge clearances on the new highway would be up to 6.5m so the interchanges would be around 8m high.
Originally the northern section of the new highway included a single carriageway and at-grade intersections at Stock Rd, Neaves Rd and Muchea.
But when the tenders were let for the northern section of NorthLink WA, the construction industry in Western Australia was highly competitive so the project was upgraded to a four-lane highway.
Main Roads WA said the four-lane highway would take about 80 per cent of heavy traffic away from Great Northern Hwy.
The updated project allows for a dual carriageway between Maralla Rd and Muchea, interchanges at Stock Rd, Neaves Rd and Brand Hwy, a deviation at Brand Hwy and flyovers at Muchea South Rd, railways and Ellenbrook.
There will be a community drop-in session providing information about the NorthLink WA central section’s landscaping in Ellenbrook this weekend.
Two million trees and 800kg of seed will be used to landscape the central section.
Main Roads WA said an important part of the work involved providing adequate landscaping and screening between properties and the noise wall in Ellenbrook.
The sessions will also be an opportunity for residents to provide further input or comment before the landscaping design are finalised.
The Great Northern Connect community and stakeholder engagement team will have a display at Ellenbrook Library, 90 Main Street, Ellenbrook on Sunday, October 29 from 1pm to 4pm.
There will be artist’s impression images of landscaping, information about species, planting densities and height at maturity, plans for ongoing maintenance and more.
If residents cannot make a community drop-in session they can call 1800 874 998 or email email@example.com
