The Knight+Street+Corridor mostly has the potential to provide 3 lanes each way. However, the middle of the Knight_Street_Bridge and the Clark Drive diversion only has 2 lanes each way. However, by 12th Avenue, Clark Drive would be 6_lanes_wide up to Hastings Street.
Despite the Knight_Street_Bridge opening in the 1970s for a seaport city, it wasn't designed to have 2 bus lanes, 2 HOV lanes & 2 truck lanes or even 2 emergency lanes. It was hardly designed with any future corridor-capacity in mind. Such narrow sidewalks that there should have been a bus & bike bridge built next to it decades ago.
