Missouri state troopers say MoDOT is working with a contractor for the immediate demolition of the Sorrels overpass, which will involve rerouting of I-70 just west of Columbia. Boone County firefighters say the Sorrels overpass over I-70 remains closed this (Tuesday) morning, after a waste management truck struck the overpass. The collision has caused significant bridge damage. Boone County Fire Protection District assistant chief Gale Blomenkamp tells 9KWOS that the truck driver was uninjured. Blomenkamp also says the women whose vehicle was then struck by debris were NOT injured either. The crash closed one lane of westbound I-70 for the entire afternoon.
