Design of 110m long pedestrian bridge in Elizabeth Quay inlet unveiled Concept image of the new bridge that will be built at Elizabeth Quay. IT'S set to be a unique addition to Perth's skyline, a popular vantage point and a vital link in the Elizabeth Quay inlet. The design for a 110m long pedestrian bridge was released today, which Planning Minister John Day said would be an important connection between the cafes and bars on the promenades, the island and the new ferry terminal. The bridge will be generous enough to accommodate cyclists and pedestrians, sit high enough above the water for most boats to pass underneath and will incorporate feature lighting to add to the night-time ambience of the quay. "The $440 million project is well advanced with construction of the inlet on track for a spring 2015 completion," the minister said. Dredging works start next week to allow boats to enter the future inlet. A 300m section of Riverside Drive will be permanently closed from next Tuesday. When finished, Elizabeth Quay is expected to draw more than four million visitors a year, be the workplace for 10,000 people and home to a population of 1400 residents.
