All drivers are advised that the Jefferson Street Viaduct will be closed to traffic Monday, July 8 through Friday July 11 for regular structural engineering inspection required by the Iowa Department of Transportation. Motorists will need to seek alternate routes during this time.
The inspections must be completed in order to be in compliance with state regulations and to qualify for repair funding. A portion of the inspection will be conducted using a specialized â??snooper truckâ?? that lifts inspectors over the railing and allows them to view the underside of the bridge.
