Construction on the roundabout and pedestrian underpass at the intersection of Princess Street and State Highway 3 started in March 2023 and was completed in July 2024.
The Princess Street roundabout was built first because this intersection has the highest crash rate. There were 17 crashes at this intersection between 2017 and 2021 – more than any of the other intersections along the route.
A unique feature of the Princess Street roundabout is the pedestrian underpass which provides a safe place for people to cross the road – including students walking to and from Waitara High School, which is located on Princess Street.
As well as the roundabout and underpass, stretches of flexible median barrier have been installed on the highway before and after the roundabout. These barriers help prevent deadly head on crashes.
