In Portage, police say a man has been airlifted to a Chicago-area hospital with serious injuries after a single-vehicle crash on Route 12 at the US Steel bridge. Officers began investigating the crash just after seven-o'clock this morning. Portage Police Public Information Officer Sgt. Keith Hughes says the passenger vehicle involved was traveling east on US 12 and crashed into the west side concrete wall that supports the bridge. Police say the vehicle was occupied by one male subject who has yet to be identified. Police say the bridge remains open, but traffic in the area had lane restrictions due to the ongoing investigation by the Portage Crash Team.
