• Joshua Morrison/News Mount Vernon Engineer Brian Ball, measures the depth of the cistern discovered under Gay Street. At 12 feet and 3 inches deep, 43 feet long and 8 feet across, the hole started as a short dip in the bricks. Crews filled the hole with nearly 100 tons of gravel before using cement. The cisterns were used as storage for the fire department as far back as the 1880s. Gay Street reopened Tuesday afternoon.

MOUNT VERNON — The old cisterns that caused a sinkhole to develop in the 400 block of North Gay Street have been filled in and the street is reopened.

City Engineer Brian Ball said there turned out to be two cells in the old storage unit, each about 25 feet long. The north end was “soupy” and was where most of the erosion and subsequent sinking had occurred, Ball said, but as they approached the south end, it was compacted and intact, so they did not dig that up.
