CLEARING vegetation for the extension of Mitchell Fwy to Romeo Rd will start later this year, according to Main Roads WA.

Construction of the 5.6km northern extension of the Mitchell Fwy from Hester Ave to Romeo Rd will start early next year with the project scheduled for completion in late 2022.

A Main Roads WA update on the project said key features of the freeway extension, which will have two lanes in each direction, include a northbound on-ramp and southbound off-ramp at the Hester Ave interchange, an interchange at Lukin Dr ( the eastern section of Lukin Dr ends at the interchange), a road bridge over the Nowergup railyard access road, a rail tunnel-bridge for the rail to exit the freeway median to Butler about 500m north of Lukin Dr, a northbound on-ramp and southbound off-ramp at Romeo Rd where the freeway terminates.

The project also includes an upgrade from three-way to four-way signalised, an intersection at Romeo Rd and Marmion Ave, a dual carriageway on Romeo Rd from Wanneroo Rd to Marmion Ave.

Wanneroo Rd will be duplicated for about 1.5km north of Romeo Rd and about 300m south of Romeo Rd, including an intersection upgrade at Romeo, Wanneroo and Karoborup roads.

There will be a principal shared path on the west side of the freeway connecting to the existing path north of Hester Ave.

The project also includes noise walls, service relocations (water, gas, power, communications, sewerage etc, lighting to the Mitchell Fwy, Wanneroo and Romeo roads, side street and principal shared path and safety barriers to separate the railway and freeway corridors.

The update said three areas of optional works had also been identified.

These include the duplication of Wanneroo Rd south to Dunstan Rd with pedestrian-fauna underpass and interchange at Nowergup Rd, a freeway interchange for Butler Blvd and widening works for Lukin Dr west to Connolly Dr.

“These options will be decided upon following the assessment and engagement of a design and construction contractor and will be advised in the coming months,’’ the update said.

In Contractors short-listed for freeway extension to Romeo Rd, April 28 the Morrison and McGowan governments announced that two building contractors, which had been shortlisted for the Mitchell Fwy extension from Hester Ave to Romeo Rd project, were due to submit their quotes by July 2020.
