Photos of utility crews fixing a broken water main at Division st and 10th st in SoMa (San Francisco)

The contractors let me take a few amazing shots of their repair work.­ They installed two large cut-off valves on an old bypass water pipe that exploded on December 13th, 2009, causing a huge sink-hole in Division Street.­

Photos of construction workers at work, with their heavy machinery and power tools.­

Road construction, infrastructure, building constructions etc.­
