A semi rests on its side near 1500 W. Center in Provo on Thursday after its driver failed to put its lift back down after dropping off a metal trash container. As the truck passed under the viaduct, it hit the top and toppled. Traffic was stalled for over 30 minutes. The semi's driver was not cited, Provo Police Sgt. Matt Siufanua said.
