SUPPLEMENTARY INFORMATION: The California Department of Transportation 
has requested a temporary change to the operation of the Highway 160 
drawbridge, mile 0.1, over Three Mile Slough, at Rio Vista, CA. The 
drawbridge navigation span provides 12 feet vertical clearance above 
Mean High Water in the closed-to-navigation position. In accordance 
with 33 CFR 117.5, the draw opens on signal. Navigation on the waterway 
is commercial, search and rescue, law enforcement, and recreational.
    The drawbridge will be secured in the closed-to-navigation position 
from 12:01 a.m. on January 5, 2016 to 11:59 p.m. on April 10, 2016, to 
allow the bridge owner to perform sand blasting and painting 
rehabilitation. A containment scaffolding system will be installed 
below low steel of the entire length of the bridge structure, reducing 
vertical clearance for navigation by not more than 4 feet, and will be 
lighted at night with red lights. This temporary deviation has been 
coordinated with the waterway users. No objections to the proposed 
temporary deviation were raised.
    Vessels able to pass through the bridge in the closed position may 
do so at any time. The bridge will not be able to open for emergencies. 
The confluence of the San Joaquin and Sacramento rivers can be used as 
an alternate route for vessels unable to pass through the bridge in the 
closed position. The Coast Guard will also inform waterway users 
through our Local and Broadcast Notices to Mariners of the change in 
operating schedule for the bridge so that 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: December 15, 2015.
D.H. Sulouff,
District Bridge Chief, Eleventh Coast Guard District.
