Don't be alarmed if you see a bus driving on the shoulder! It’s the BOSS at work for you! The Bus on Shoulder System allows authorized transit buses with trained drivers to operate on the shoulders of selected freeways at low speeds in order to bypass congested traffic and maintain transit schedules. This is a low-cost treatment that can provide immediate benefits to transit whenever travel is experiencing moderate to heavy degrees of congestion.
Currently, GoTriangle Routes 100, 800, CRX, and DRX take advantage of the BOSS program. Authorized transit buses can travel on the shoulder at speeds up to 35 mph, as long the bus stays within 15 mph of general purpose travel speeds. Shoulder use for emergencies will continue to take precedence over BOSS operation.
