Two accidents involving three semi-trailer rigs closed down both northbound and southbound lanes of Interstate 15 in southern Utah Wednesday morning.
By 11:45 a.m., The Utah Highway Patrol said wreckage had been cleared and traffic flow returned to normal along the southbound Cedar City to St. George corridor. Northbound lanes had reopened two hours earlier.
Efforts to reopen the southbound lanes were slowed by cleanup by hazardous materials workers of an estimated 4,000 gallons of fuel that spilled from a Maverik store semi's tanker trailers. UHP Cpl. Todd Johnson also confirmed that investigators were looking into whether the semi driver in that 2:12 a.m. crash on southbound I-15 near mile post 40 was impaired.
