SPANISH FORK — Two people sustained critical injuries Thursday morning in a semi-trailer rollover in Spanish Fork canyon.
The crash occurred around 5:50 near mile marker 186.
According to Utah Highway Patrol Sgt. Todd Royce, the semi-trailer rolled and went down an embankment into a gully.
The truck was traveling west and hauling two trailers at the time of the crash.
The crash forced UHP officials to close S.R. 6 in both directions for about 20 minutes as two medical helicopters were flown in to transport the victims.
Both victims were occupants of the semi-trailer. No other vehicles were involved in the crash.
