If you live, work or drive along McAllister Street between Larkin and Leavenworth streets, more of the city's seemingly ubiquitous street construction is headed your way, but the results could be a boon for pedestrians who frequent the two-block stretch. 

At 10:30am today, Transportation Authority Board member Jane Kim and UC Hastings Board Chair Carin T. Fujisaki kicked off the official groundbreaking of a new pedestrian safety project. The project aims to implement a series pedestrian safety improvements and increase accessibility to the 5-Fulton Muni line. 

The project, which is part of the city's Vision Zero policy goal of reducing eliminating traffic-related fatalities, is aiming to wrap up in the summer 2015, so it'll be a good 6-8 months before you can expect this one to be completed. 

Update, 2:30pm: It seems the project may have started too late for one pedestrian, as the Examiner reports that a woman in her 60s was critically injured when she was hit by a "cable car-style" tour bus in a crosswalk near City Hall (near where the improvements are planned). The incident occurred at about 11:30am today. The woman was transported to SF General with life-threatening injuries. According to the Chronicle, the woman was stuck in the mid-block crosswalk on Dr. Carlton B. Goodlett Place — which connects City Hall to Civic Center Plaza.

Update, 4pm: KCBS reports that the woman has died of injuries sustained in the accident. According to SFist, the woman 67-year-old woman has been identified as a staffer with the City Controller's Office. SFPD's Commander Mikail Ali said that the driver of a Classic Cable Car Company Coach was apparently not paying attention to the road as the woman crossed the street this morning.  “Probably there was some level of distraction from what was taking place in the roadway in front of the vehicle."
