SALT LAKE CITY — An explosion underground on Main Street caused power outages in parts of Salt Lake City Saturday.
The Salt Lake City Fire Department Capt. Chad Jefferson said about 30 firefighters responded to the explosion at 3:30 a.m. on 300 South and Main Street.
Crews lifted manhole covers and found fire coming from the electrical vaults.
The fires caused power outages in the area, affecting traffic lights, TRAX lines and nearby buildings.
The Salt Lake City Police Department said hazmat crews metered the area when gasses were found after the explosion.
Temporary traffic delays
The SLCPD said some roads were temporarily closed as the fire department worked. All road closures related to the explosion were reopened by 8 a.m.
Jefferson said the power outage will probably grow.
The Utah Department of Transportation set up generators to power some traffic lights but Jefferson said some lights may still be down.
“If people do come into this area and there are lights that are out or malfunctioning, remember those are treated as a four-way stop,” Jefferson said.
The cause of the explosion is under investigation.
This story is breaking and will be updated as more information becomes available.
