Drawbridge Operation Regulation; Upper Mississippi River, Rock Island, IL
The Coast Guard has issued a temporary deviation from the operating schedule that governs the Rock Island Railroad and Highway Drawbridge across the Upper Mississippi River, mile 482.9, at Rock Island, Illinois. The deviation is necessary to allow the bridge owner time to perform preventive maintenance and critical repairs that are essential to the continued safe operation of the drawbridge. The work is scheduled in the winter, when the impact on navigation is minimal, instead of scheduling the work at other times in the year, when river traffic is prevalent. This deviation allows the bridge to be maintained in the closed-to-navigation position for 77 days.
