UPDATE 1:40pm: The water has receded and MSD is on the scene. Third Street has become a muddy wasteland and workers are scraping as much as possible off the streets. WLKY is the first mainstream news crew on the scene. New photos after the jump.
While visiting the Urban Design Studio at about 12:30pm today, workers working on a presumably a gas pipeline at the corner of Third Street and Muhammad Ali Boulevard struck a water main, sending what looked like millions of gallons of muddy water onto Third Street.
As of 1:20, the water main seems to have been turned off, but water still fills the streets and sidewalks. Water reached the threshold to the Urban Design Studio and began flooding inside. Aggravating the problem, motorists shunning popular advice drove through the eight plus inches of water sending wave upon wave lapping against the building doors and into the Studio.
Adjacent buildings suffered worse damage with elevator pits and basements flooded. After the click are several photos of the damage as it unfolded.
