SUPPLEMENTARY INFORMATION: The Canadian National Railway Company 
requested a temporary deviation for the Dubuque Railroad Drawbridge, 
across the Upper Mississippi, mile 579.9, at Dubuque, Iowa to open on 
signal if at least 24 hours advance notice is given in order to 
facilitate needed bridge maintenance and repairs. The Dubuque 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. In order to facilitate the needed bridge 
work, the drawbridge must be kept in the closed-to-navigation position. 
This deviation allows the bridge to open on signal if at least 24 hours 
advance notice is given from 12:01 a.m. January 15, 2010 until 9 a.m., 
March 15, 2010.
    There are no alternate routes for vessels transiting this section 
of the Upper Mississippi River.
    The Dubuque 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. These interests will not be significantly 
impacted due to the reduced navigation in winter months. 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: 22 December 2009.
Roger K. Wiebusch,
Bridge Administrator.
