Muni's new 55-16th Street line was sighted in service on Monday, with buses making runs between the 16th Street BART station and Mission Bay, nearly a week ahead of the official launch date on Saturday. Kyle Barlow sent in these photos of buses making stops at the University of California SF hospital, set to open next week, and said the buses were taking passengers.
It's not every day you see a new Muni line.
