Route 66, which travels along the busway to connect the University of Queensland and the Royal Brisbane and Women’s Hospital, was Brisbane’s most popular bus route, carrying 3.1 million people a year.

A Monday-to-Friday loop service running from Deagon to Shorncliffe had the lowest patronage, with 1968 passengers in a year.
