SUPPLEMENTARY INFORMATION:

The Rock Island Arsenal requested a temporary deviation to allow time to conduct repairs to the Rock Island Railroad and Highway Drawbridge, mile 482.9, at Rock Island, Illinois across the Upper Mississippi River. The Rock Island Railroad and Highway Drawbridge currently operates in accordance with 33 CFR 117.5 which requires the drawbridge to open promptly and fully for passage of vessels when a request to open is given in accordance with 33 CFR 117, subpart A. In order to facilitate required bridge maintenance, the bridge must be kept in the closed-to-navigation position. This deviation allows the drawbridge to remain closed-to-navigation for two hours from 9 a.m. until 11 a.m., June 4, 2005. There are no alternate routes for vessels transiting this section of the Upper Mississippi River.

The Rock Island Railroad and Highway Drawbridge, in the closed-to-navigation position, provides a vertical clearance of 23.8 feet above normal pool. Navigation on the waterway consists primarily of commercial tows and recreational watercraft. This deviation has been coordinated with waterway users. No objections were received.

In accordance with 33 CFR 117.35(c), this work will be performed with all due speed in order to return the bridge to normal operation as soon as possible. This deviation from the operating regulations is authorized under 33 CFR 117.35.

Dated: May 3, 2005.

Bridge Administrator.
