An SUV involved in a three-vehicle collision late Saturday veered off 13400 South and 5200 West in Herriman, Utah, ploughed into a Domino’s Pizza outlet and ruptured a natural-gas line. The impact ignited a fire that moments later triggered a powerful explosion visible across the southwest Salt Lake Valley. Unified Fire Authority said the blast destroyed the Domino’s restaurant and caused major damage to neighbouring Jimmy John’s and Supercuts businesses. Debris rained onto the roadway and the building’s roof was blown off. Two bystanders pulled the SUV’s driver and passenger from the burning vehicle, and a third crash victim escaped separately. Riverton Police reported that all three were transported to hospital; no fatalities and no injuries among the more than 60 firefighters who responded from six departments. Authorities issued a reverse-911 alert ordering residents of Terra Crus Lane and Parasol Lane to evacuate and closed 13400 South in both directions while utility crews shut off the gas. The leak was contained and evacuees were allowed to return at 1:05 a.m. Sunday. Police are investigating the cause of the initial crash, and city officials said the long-term future of the strip mall is still being assessed.
