Presently, bus shoulder lanes on the Queensway provide fast and reliable transit service. The lanes provide transit vehicles with their own specific lane that cannot be used by other vehicles. In Ottawa's west end the shoulder lanes stretch form Moodie Drive to Eagleson Road. In the east end bus shoulder lanes are on Regional Road 174 between Blair Road and Place d'Orleans.
As illustrated below, 2 buses at full capacity can carry more passengers than 60 cars in 2 other lanes of traffic.
