Drawbridge Operation Regulation; Upper Mississippi River, Clinton, IA

The Coast Guard has issued a temporary deviation from the operating schedule that governs three drawbridges crossing the Upper Mississippi River in Iowa: The Illinois Central Railroad Drawbridge, mile 579.9, Dubuque, IA; the Sabula Railroad Drawbridge, mile 535.0, Sabula, IA; and the Clinton Railroad Drawbridge, mile 518.0, Clinton, IA. The deviation is necessary to allow the bridge owners time to perform preventive maintenance that is essential to the continued safe operation of the drawbridges and allows for a seasonal deviation issued for these bridges each year. Maintenance is scheduled in the winter, when there is less impact on navigation due to less traffic. This deviation allows the bridges to open on signal if at least 24 hours advance notice is given.
