ST. CLOUD, Minn. – December 1998 was unseasonably mild.
That meant crews installing fiber-optic cable in St. Cloud were able to work longer into the season because the ground wasn't yet frozen.
So when a crew installing a utility pole anchor on the south side of 1st Street N. in downtown St. Cloud on Dec. 11, 1998, encountered a problem, it wasn't frozen dirt.
It was a large granite slab hidden under the sidewalk. When the anchor hit that slab 20 years ago, it bent and its tip ruptured a gas pipeline.
The crew immediately noticed dirt blowing out of the hole in the sidewalk and began to smell gas.
The crew's foreman called his supervisor and the crew blocked off the area. But the utility company and fire department were not immediately notified.
Meanwhile, the gas seeped through the crumbling foundation of Bellantti's Pizza — kitty-corner from Howie's Sports Bar & Grill — and into the basement, where it reached an ignition source, possibly a gas water heater.
About 40 minutes after the granite slab was struck, the Bellantti's Pizza building exploded.
