[Docket No. USCG-2014-0978]


Drawbridge Operation Regulation; Upper Mississippi River, 
Dubuque, IA

AGENCY: Coast Guard, DHS.

ACTION: Notice of deviation from drawbridge regulations.

-----------------------------------------------------------------------

SUMMARY: The Coast Guard has issued a temporary deviation from the 
operating schedule that governs the Illinois Central Railroad 
Drawbridge, across the Upper Mississippi River, mile 579.9, at Dubuque, 
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 
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. 
It further allows the bridge to remain closed for up to 72 hours in 
duration occasionally to replace larger components as long as 72-hours 
notice is given to the USCG District Eight Western Rivers Bridge 
Branch.

DATES: This deviation is effective from 5 p.m., December 15, 2014 until 
9 a.m., March 1, 2015.
