Cathedral Avenue - Sanford Street Roundabout

The Cathedral Avenue and Sanford Street intersection, one of the busiest in the CBD, is being transformed into a roundabout to improve traffic safety and the general flow of traffic in the area in alignment with CBD revitalisation plans. Read more here

Over the years traffic congestion has steadily increased along Cathedral Avenue in the vicinity of the schools with almost 9,000 vehicles traveling through the intersection every day. Peak hour traffic, which happens around school pick-up and drop-off times, sees over 800 vehicles between 8-9am and nearly 1000 vehicles from 3-4pm traveling through the intersection.

Converting the intersection to a roundabout will enable drivers entering or exiting Cathedral Avenue at the intersection to do so in a quicker and safer way and provide pedestrians with a safer way to cross the road.

The City offset the removal of the tree by planting trees the same number of trees in the landscaping of the roundabout.
