Mitchell Freeway Extension

The Mitchell Freeway extension from Hodges Drive to Burns Beach Road was constructed to provide a connection between the CBD and the ever extending northern suburbs. The project included the construction of a freeway (comprising two lanes in each direction, with the capacity to expand to three lanes) four (4) major bridges, rail realignment and tunnel construction, pedestrian overpass and several pedestrian underpasses. Fremantle constructions was responsible for supplying Macmahons with skilled concrete and formwork teams for bridge and tunnel works, as well as rigging teams to install tunnel arches, noise wall post and panel structures, as well as insitu and precast abutment walls. The Highway was constructed to freeway standard from Safety Bay Road to South Yunderup, a distance of some 32 km. The remainder of the route (38 km) will be built as a rural highway, with the ability to upgrade it in the future as traffic demands increase. The project doubles the length of the existing freeway network and provides a high standard inter-regional road link that will improve transport connectivity and road safety. Fremantle constructions was engaged by the SGA to build: 2 x 220m bridges sub and superstructure. 2 x substructure of 220m bridge through a river 3 x 70m dual carriageway two span bridge 42 x drainage structures, from 10m single 600mm centres Structure through to 130lm 2m height x 12m wide structures
