The SFMTA plans to launch a 5-Fulton Limited line, remove some excess stops, move stops across intersections for smoother loading, and extend the length of bus zones to make room for double bus loading. Early next year, planners said bus bulb-outs would be also be added at seven intersections as part of a re-paving project on Fulton west of 25th Avenue.
A road diet would also be implemented on Fulton between Stanyan Street and Central Avenue, reducing four traffic lanes to two, plus turn lanes. Aside from calming traffic, SFMTA planners said that change would allow for wider traffic lanes to safely fit buses. Currently, the buses must squeeze into 9-foot lanes, resulting in a high frequency of collisions with cars. The new lanes would be 12.5 feet wide.
The new 5-Limited would run the entire length of the route using the 5′s regular electric trolley coaches, serving only the six most heavily-used stops between Market Street and 6th Avenue, running that stretch 17 percent faster than the existing local service, planners said. From the Transbay Terminal to the beach, the 5L would run 11 percent faster than the existing service.
Local bus service, which would be served with hybrid motor buses, would only run as far west as 6th Avenue, and run that stretch 7 percent faster. That means anyone looking to use a local stop on the middle stretch east of 6th, coming to or from the western stretch, would have to transfer between a 5L bus and a 5-local, though planners said relatively few riders seem to make such trips. The 5-Limited would stop running at 7 p.m., after which electric trolley coaches would serve every stop on the line.
With the 5L carrying the bulk of rush-hour commuters on the route at a faster clip, Muni planners say the improvements will go a long way toward reducing crowding. At daytime hours, between 6 a.m. to 6 p.m., the 5 currently runs at an average speed of just 9 mph, said SFMTA planner Dustin White.
