33 CFR Part 117

[Docket No. USCG-2010-1080]


Drawbridge Operation Regulation; Upper Mississippi River, 
Hannibal, MO

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 
Hannibal Railroad Drawbridge across the Upper Mississippi River, mile 
309.9, at Hannibal, Missouri. The deviation is necessary to allow the 
bridge owner time to replace critical control components 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 remain in the 
closed-to-navigation position during work performance.

DATES: This deviation is effective from 12:01 a.m., January 5, 2011 to 
12:01 a.m., January 26, 2011.

SUPPLEMENTARY INFORMATION: The Norfolk Southern Railroad requested a 
temporary deviation for the Hannibal Railroad Drawbridge, across the 
Upper Mississippi River, mile 309.9, at Hannibal, Missouri to remain in 
the closed-to-navigation position for 21 days from 12:01 a.m., January 
5, 2011 to 12:01 a.m., January 26, 2011 to allow the bridge owner time 
for preventive maintenance. The Hannibal 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) from January 
3, 2011 to March 4, 2011 will preclude any significant navigation 
demands for the drawspan opening.
    The Hannibal Railroad Drawbridge, in the closed-to-navigation 
position, provides a vertical clearance of 21.1 feet above normal pool. 
Navigation on the waterway consists primarily of commercial tows and 
recreational watercraft. The drawbridge will remain in the closed-to-
navigation position for the 21-day period, January 5, 2011 to January 
25, 2011. This temporary deviation has been coordinated with waterway 
users.
    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.
