99 B-Line

The 99 B-Line is an express bus line with bus rapid transit elements in Metro Vancouver, British Columbia, Canada. It travels along Broadway, a major east–west thoroughfare, and connects the University of British Columbia (UBC) to Commercial–Broadway station on the SkyTrain system. It is operated by Coast Mountain Bus Company and funded by TransLink.

It is the first and the most popular of the B-Line routes in the regional system. The other B-Lines that followed are based on the 99 B-Line in terms of the use of articulated buses (which can carry 120 passengers) and frequent arrivals for buses. The waiting time for a bus during peak hours on a weekday is 1.5–3 minutes. All of the buses on this route are built by New Flyer Industries of Winnipeg, Manitoba. On average it takes 42 minutes to complete the entire route, or half an hour near the last runs at the end of the night.

The 99 B-Line was the busiest bus route in Canada and the United States in 2018, with an average weekday ridership of 55,900 passengers. This number had increased from approximately 45,000 passengers per day in 2007. The COVID-19 pandemic and subsequent demand and service changes lowered the ridership of the line; by 2024, it saw around 34,160 trips per weekday, about 60 percent of its peak levels of 57,240 in 2019. Ridership across the overall TransLink network returned to 90 percent of pre-pandemic levels during the same time period.
