The woman was struck by a Muni bus this afternoon while walking in the Castro District died, according to SFPD.
Police say the woman -- who was only identified as between the ages of 25 and 30 -- was at the corner of 18th and Hartford streets, about 90 percent through the crosswalk when the Muni bus hit her.
Sergeant Michael Andraychak says the accident happened at about 2:30 p.m. The bus had just gone out of service and was being rerouted to supplement the F line on Market Street when the accident happened. The driver made a left-hand turn on 18th Street and hit the female pedestrian.
Muni spokeswoman Kristen Holland tells us they might be able to route around the accident. We will report the story as it unfolds. Check back for updates.
