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 in order to facilitate needed bridge maintenance and repairs. The Rock Illinois Central Railroad Drawbridge currently operates in accordance with 33 CFR 117.5, which states the general requirement that drawbridges must 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 7 a.m. December 16, 2012 until 7 a.m., March 4, 2013.
There are no alternate routes for vessels transiting this section of the Upper Mississippi River.
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 effective period of this temporary deviation. This deviation from the operating regulations is authorized under 33 CFR 117.35.
