Coast Guard, DHS.
Notice of temporary deviation from regulations.
The Commander, Eighth Coast Guard District, has issued a temporary deviation from the regulation governing the operation of the Clinton Railroad Drawbridge across the Upper Mississippi River, mile 518.0, at Clinton, Iowa. The deviation is necessary to allow the bridge owner time to perform preventive maintenance that is essential to the continued safe operation of the drawbridge. Maintenance is scheduled in the winter and when there is less impact on navigation; instead of scheduling work in the summer, when river traffic increases. This deviation allows the bridge to open on signal if at least 24 hours advance notice is given.
This deviation is effective from 12:01 a.m., December 15, 2010 to 9 a.m., March 1, 2011.
