When good rivers turn bad: Extreme flooding
Case study - The Johnstone River, Far North Queensland

Bruce Highway

Impact of Lowering Bruce Highway - Click to enlargeThe Bruce Highway is the major and only coastal main north south highway in the region. In order to prevent road transport from being stopped by minor flooding across the highway, it was raised sometime in the past. During major flooding the highway acts as a giant low dam, backing up huge volumes of water and making it harder for the area to quickly drain of flood waters. In backing up there is potential for the waters to flood numerous home and businesses.
