An unexpected underground explosion shook downtown Salt Lake City early Saturday morning, leading to a thorough investigation by emergency crews and causing widespread power outages. Authorities first received reports of the incident near 300 S. Main at approximately 3:30 a.m., prompting an urgent response from local firefighters.

About 30 firefighters were dispatched to the scene, according to KSL, where they found multiple dislodged manhole covers and street damage. Salt Lake Fire Division Chief Bob Silverthorne stated that road repairs would be necessary, but the extent of the underground damage remained unknown. Investigators are currently working to pinpoint the cause of the explosion, sifting through the debris for answers.

The incident also affected the local power grid, leading to an outage that interrupted traffic signals, impacted the operation of TRAX lines, and left buildings without electricity. Fire crews assessed the area for any gas leaks and potential public safety threats, as detailed by ABC4.

This disruption extended to the Utah Transit Authority's TRAX system, which experienced significant delays and route closures in the affected area, FOX13 reported. The full impact of the explosion on the city's infrastructure, including the transit system, is still being assessed as authorities work to restore normalcy to downtown Salt Lake City.
