SUPPLEMENTARY INFORMATION:

The U.S. Army Rock Island Arsenal requested a temporary deviation for the Rock Island Railroad and Highway Drawbridge, across the Upper Mississippi River, mile 482.9, at Rock Island, Illinois. The bridge has a vertical clearance of 23.8 feet above normal pool in the closed-to-navigation position. This bridge is governed by 33 CFR 117.5.

This deviation allows the bridge to remain in the closed-to-navigation position from 6 a.m. through 9 a.m. on September 9, 2017. Navigation on the waterway consists primarily of commercial tows and recreational watercraft. This temporary deviation has been coordinated with waterway users. No objections were received.

The bridge will not be able to open for emergencies and there are no alternate routes for vessels transiting this section of the Upper Mississippi River. The Coast Guard will inform users of the waterways through our Local and Broadcast Notices to Mariners of the change in operating schedule for the bridge so the vessel operators can arrange their transits to minimize any impact caused by the temporary deviation.

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.

Dated: August 25, 2017.
