PHOENIX -- A wreck involving a semi forced the closure of westbound Interstate 10 at about 75th Avenue for hours Thursday morning.
It happened at about 6:30 a.m. The freeway was completely shut down for about an hour. By 7:30 a.m., the Department of Public Safety had opened one lane to allow traffic to crawl by the wreck. Opening that one lane was an effort to clear out the vehicles that had already passed the 75th Avenue exit ramp. That backup was finally cleared shorty before 8 a.m.
With the roadway clear and the lanes closed, detectives were free to conduct their investigation.
According to DPS, the truck was heading west when a car that reportedly was traveling at about 100mph hit it. The truck jackknifed into the cable barrier, landing in the median that separates the westbound and eastbound sides of the freeway.
One person was seriously hurt in the wreck. A second suffered minor injuries. Both were taken to the hospital.
Investigators are trying to determine why the vehicle that hit the semi was speeding. They have not yet ruled out impairment as a factor in the wreck.
DPS was able to re-open the freeway shortly before 10:30 a.m.
