Background
In heavy rains, both Port and Woodville Roads in Adelaide’s western suburbs were prone to flooding. In a 1-in-100-year rainfall event, these major roads experienced knee-deep water, making them unusable and impacting on access to Queen Elizabeth Hospital, almost 4,000 homes, and a number of local businesses.
The Port Road Drainage Upgrade mitigates this flood risk by replacing the existing trunk mains in the Port Road central median with two parallel trunk mains between Old Port Road in Cheltenham and Park Street South in Woodville.
