Agency: Coast Guard, DHS
Action: Notice of temporary deviation from regulations
Citation: FR Doc. 2011-30288 · Docket No. USCG-2011-1039 · 33 CFR 117

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 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 19, 2011 to 7 a.m., February 27, 2012.

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 70 days from 12:01 a.m., December 19, 2011 to 7 a.m., February 27, 2012 to allow the bridge owner time for preventive maintenance. The Rock Illinois Central Railroad Drawbridge currently operates in accordance with 33 CFR 117.5, which states the general requirement that the drawbridge 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 16 (Mile 457.2 UMR), Lock No. 17 (Mile 437.1 UMR) and Lock No. 18 (Mile 410.5 UMR) until 7:30 p.m., February 28, 2012 will preclude any significant navigation demands for a 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 4, 2011. Eric A. Washburn, Bridge Administrator, Western Rivers.
