Great Northern Highway - ​Roy Hill Bridge

The bridge will be privately funded by Roy Hill Iron Ore and will replace the existing level crossing along Great Northern Highway.

Once the bridge has been constructed and the minor realignment of the highway is complete, the existing level crossing will be removed and the 80 km/h speed restriction will be removed. The current level crossing is located approximately 25 to 30 km South-West of Port Hedland.
