Hundreds of people were evacuated from the Consumer Reports building in Yonkers this morning after a water main ruptured, sending water gushing everywhere.

A pipe about 4 feet underneath the front of the building on Executive Boulevard burst just before 10:30 a.m.

About 500 people were evacuated when hundreds of gallons of water went gushing, creating unstable concrete. The employees were allowed back inside, but they have to use an alternate entrance on the north side of the building.

The water department shut the main off on King Street and immediately went to work on fixing the problem. It is still unclear why the pipe burst.
