[Docket No. USCG-2010-1039]


Drawbridge Operation Regulation; Upper Mississippi River, 
Dubuque, IA

AGENCY: Coast Guard, DHS.

ACTION: Notice of temporary deviation from regulations.

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

SUMMARY: The Commander, Eighth Coast Guard District, has issued a 
temporary deviation from the regulation governing the operation of 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 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.

DATES: This deviation is effective from 12:01 a.m., December 13, 2010 
to 7 a.m. March 1, 2011.

SUPPLEMENTARY INFORMATION: The Chicago, Central & Pacific Railroad 
requested a temporary deviation for the Illinois Central Railroad 
Drawbridge, across the Upper Mississippi River, mile 579.9, at Dubuque, 
Iowa to open on signal if at least 24 hours advance notice is given for 
79 days from 12:01 a.m., December 13, 2010 to 7 a.m., March 1, 2011 to 
allow the bridge owner time for preventive maintenance. The Illinois 
Central Railroad Drawbridge currently operates in accordance with 33 
CFR 117.5, which states the general requirement that drawbridges shall 
open promptly and fully for the passage of vessels when a request to 
open is given in accordance with the subpart.
    There are no alternate routes for vessels transiting this section 
of the Upper Mississippi River.
    Winter conditions on the Upper Mississippi River coupled with the 
closure of Army Corps of Engineer's Lock No. 20 (Mile 343.2 UMR), Lock 
No. 21 (Mile 324.9 UMR) and Lock No. 22 (Mile 301.2 UMR) until 4:30 
p.m., March 4, 2011 will preclude any significant navigation demands 
for the drawspan opening.
    The Illinois Central Railroad Drawbridge, in the closed-to-
navigation position, provides a vertical clearance of 19.9 feet above 
normal pool. Navigation on the waterway consists primarily of 
commercial tows and recreational watercraft. The drawbridge will open 
if at least 24 hours advance notice is given. This temporary deviation 
has been coordinated with waterway users. No objections were received.
    In accordance with 33 CFR 117.35(e), the drawbridge must return to 
its regular

operating schedule immediately at the end of the designated time 
period. This deviation from the operating regulations is authorized 
under 33 CFR 117.35.

    Dated: November 10, 2010.
Eric A. Washburn,
Bridge Administrator.
