The City of Gosnells has received confirmation that both Main Roads and the federal government will share the cost of the new $9 million Station Street Bridge.
The bridge will be dual lane, and constructed next to the existing wooden Cargeeg bridge.
The existing bridge will remain open to traffic until the new bridge is complete.
It will then be used as a shared path, allowing both pedestrians and cyclists a safe route across the river.
The design for the new bridge was previously completed by the city, and has now been handed to Main Roads for construction.
Following a program of service relocations, construction of the new concrete structure will start by the end of 2023 and take up to 10 months to complete.
Station Street will be realigned to tie into the new bridge. Local road street lighting, along with signs and line-marking, will complete the project.
To future-proof the new bridge, provision has also been made to retrofit a shared path to the structure.
The ageing Cargeeg Bridge is built from timber and currently carries about 4000 vehicles per day.
It provides an important link between the Gosnells town centre and the Martin residential area, as well as to and from local schools.
