-----------------------------------------------------------------------

SUMMARY: The Coast Guard has issued a temporary deviation from the

Mile Slough, mile 0.1, at Rio Vista, CA. The deviation is necessary to 
allow California Department of Transportation to install electrical 
equipment on the drawbridge. This deviation allows the vertical lift 
drawspan to be secured closed to navigation at various times during the 
project.

DATES: This deviation is effective from 8 p.m. July 9, 2012 to 5 a.m. 
July 12, 2012.

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.
