Engineering group Clough's joint venture with Madrid-based ACCIONA has secured works for the construction of a bridge over the new Koodaideri railway.
Under the contract, ACJV will build a single span bridge to carry Great Northern Highway over the railway, along with a 3.6 kilometre road for approaches to the new bridge.
Clough said the joint venture would also complete road upgrades to the Great Northern Highway and Koodaideri mine access road intersection.
The new contract comes six months after ACJV secured works with Rio Tinto to build the 100-kilometre Koodaideri railway, connecting the new iron ore mine to Rio's existing rail network.
“Our history with Main Roads started in 1957 and we are proud to continue being part of the ongoing development of WA’s transport infrastructure,” he said.
Work on the bridge will start on November 15 and is expected to be completed mid next year.
