SUPPLEMENTARY INFORMATION:

The Canadian Pacific Railway requested a temporary deviation for the Harry S. Truman Railroad Drawbridge, across the Missouri River, mile 359.4, at Kansas City, Missouri to remain in the closed-to-navigation position for two 60-hour individual closures while the eight wire rope lifting cables that operate the lift span are replaced. The closure period will start at 10 p.m. on or about May 15, 2012 through 10 a.m. on May 18, 2012 and again from 10 p.m. on or about May 22, 2012 through 10 a.m. on May 25, 2012.

Once the wire rope lifting cables are removed, the lift span will not be able to open, even for emergencies, until the replacement wire rope lifting cables are installed.

The Harry S. Truman Railroad Drawbridge currently operates in accordance with 33 CFR 117.687, which states the draws of the bridges across the Missouri River shall open on signal; except during the winter season between the date of closure and date of opening of the commercial navigation season as published by the Army Corps of Engineers, the draws need not open unless at least 24 hours advance notice is given.

There are no alternate routes for vessels transiting this section of the Missouri River. The Harry S. Truman Railroad Drawbridge, in the closed-to-navigation position, provides a vertical clearance of 51.3 feet above zero on W. B. gage at Kansas City, Missouri. Navigation on the waterway consists primarily of commercial tows and recreational watercraft. This temporary deviation has been coordinated with the 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.

Dated: April 9, 2012.

Eric A. Washburn,

Bridge Administrator, Western Rivers.
