SUPPLEMENTARY INFORMATION:

The California Department of Transportation has requested a temporary change to the operation of the Hwy 160 drawbridge across Three Mile Slough, mile 0.1, at Rio Vista, CA. The drawbridge navigation span provides a vertical clearance of 12 feet above Mean High Water in the closed-to-navigation position. The draw opens on signal for the passage of vessels as required by 33 CFR 117.5. Navigation on the waterway is commercial and recreational.

The vertical lift drawspan may be secured in the closed-to-navigation position from 8 p.m. to 5 a.m., July 9, 2012 to July 12, 2012, to allow Caltrans to install electrical equipment on the drawbridge. Vessels that can pass through the bridge in the closed to navigation position may continue to do so at any time. The drawspan can be opened upon one hour advance notice for emergencies if requested. An alternative path is available for navigation via the confluence of the Sacrament and San Joaquin Rivers. The drawspan will resume normal operation each day between 5 a.m. and 8 p.m. and at the conclusion of the project. This temporary deviation has been coordinated with waterway users. No objections to the proposed temporary deviation were raised.

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: June 14, 2012.

District Bridge Chief, Eleventh Coast Guard District.
