A blister island is a raised, oval-shaped traffic island designed to deflect vehicle movement sideways, encouraging lower speeds. This treatment helps make Thorpe Street safer for pedestrians, cyclists, and drivers.

If your driveway is impacted, the City will reinstate it at no cost to the property owner. Access will be maintained throughout construction, with appropriate traffic management in place to assist residents.
The City will assess existing lighting at each treatment location and upgrade it to meet Western Power standards if required.
Pending the outcomes of public consultation, works are expected to begin in the 2026/2027 financial year. Residents will be notified of the construction schedule closer to the start date.
