SUPPLEMENTARY INFORMATION: The California Department of Transportation 
has requested a temporary change to the operation of the California 
Route 160 Drawbridge over Three Mile Slough, mile 0.1, near 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 as required by 33 CFR 117.5. Navigation on the 
waterway is commercial and recreational.
    The drawspan will be secured in the closed-to-navigation position 
from 7 a.m. on November 26, 2018, through 4 p.m. on November 27, 2018, 
to allow the bridge owner to perform necessary preventative maintenance 
and non-destructive testing on the bridge's lift span gear box. 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 anytime. The bridge will not be able to open for emergencies. 
The Sacramento River and San Joaquin River can be used as alternate 
routes for vessels unable to pass through the bridge in the closed 
position. The Coast Guard will also inform the users of the waterway 
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: November 15, 2018.
