4:59 PM: It’s not blocking traffic but the response soon might – a driver has gone onto the sidewalk and (reportedly lightly) hit the building on the northeast corner of 16th/Roxbury, as shown in the traffic-cam screengrab above.

5:06 PM: Live camera shows police now have the adjacent – westbound outside – lane on Roxbury blocked.

5:19 PM: Tow truck just arrived. Apparently no major injuries, since SFD canceled quickly.

6:37 PM: Had to leave the desk for a while; the scene has since been cleared.
