The salt that the dump truck had been hauling ended up spilling off the Eisenhower overpass onto Route 83 below, state police said.

A semi-truck tipped onto its side on westbound I-290 at IL-83 in the western suburbs, spilling salt across the roadway and shutting down multiple lanes.

Traffic on the Eisenhower and Route 83 was snarled when a truck carrying salt crashed about 1:20 p.m. Wednesday on an overpass in the westbound lanes of I-290 in Elmhurst. No injuries were reported.
