SALT LAKE CITY — An underground explosion in Salt Lake City is under investigation after traffic lights and power were knocked out near 300 South Main Street early Saturday.
The explosion was first reported at approximately 3:30 a.m., with witnesses saying they had seen multiple manhole covers blown from the street and fire coming from underground.

Salt Lake City Fire says the explosion emanated from electrical vaults operated by Rocky Mountain Power. Hazmat crews dispatched to the scene detected gases and "organic compounds that can sustain explosions" near the dislodged manhole covers. They didn't not find any of the materials in any nearby buildings.
Power remains out along 400 South. UDOT crews are currently working to power traffic lights in the areas. Rocky Mountain Power is working to repair the damaged electrical equipment.
Salt Lake City Fire says they were advised by Rocky Mountain Power that further de-energization may be needed, possibly expanding the outage to a wider area. Repairs are expected to last a number of hours.
Main Street and other roads were closed from 200 South to 500 South, but have since reopened.
No injuries have been reported, and the scene is expected to clear over several hours throughout the morning.
The Utah Transit Authority says TRAX riders should expect systemwide delays on Red, Green, and Blue Line trains, due to what it's calling a sewer fire. Trains are currently not running north of Ballpark, and a bus bridge is being implemented.
