BUFFALO, NY. — Cameras caught video of a manhole cover being blown 200-300 feet into the air on Tupper Street.
Witnesses say they saw smoke coming out of a manhole around 11:30 a.m. Sunday.
Buffalo Police closed off the intersection, and two buildings were evacuated.
Then, while interviewing a witness of the first explosion, a second explosion sent a manhole cover soaring into the air.
“Heads up! Heads up! Heads up! Heads up!” the witnessed screamed.
A Buffalo Fire Department official confirms there was a third, smaller explosionaround 2 p.m.
A spokesman for the National Grid said the fire is still under investigation, but the explosions were probably caused by rapid build-up of heat, gas, and smoke that created intense pressure in the confined space under the road.
Tupper Street was closed for several hours.
