An anti-icing system is scheduled to be installed on four Interstate 80 bridges about four miles west of Aurora next week. The project will include construction of a camera tower and a building that will house the anti-icing chemicals. The Nebraska Roads Department says intermittent lane closures will be needed throughout the project on eastbound and westbound I-80. The closures will be restricted to daytime hours only and will not be imposed on weekends. The project is expected to be completed in June.
