GMF were engaged to upgrade Toodyay Rd to allow for 2.6km of new overtaking lanes and turning lanes in addition to the extension of Railway Pde connecting a recently installed bridge over Ellenbrook River.                                                            The works involved bulk earthworks and the import of fill to build up either side of bridge including backfilling abutments. The critical risks associated with the project were high voltage overhead powerlines, heavy traffic, MRWA and local residents.

 

PROJECT STATS

• 86,000m² topsoil strip with 34,000m² reused
• 62,000m² of new roads constructed
• 400m of drainage pipe & associated 25 pits
