ACTION: Notice of deviation from drawbridge regulation.

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

Mile Slough, mile 0.1, at Rio Vista, CA. The deviation is necessary to 
allow the bridge owner to complete the necessary sand blasting and 
painting rehabilitation. This deviation allows the bridge to be secured 
in the closed-to-navigation position during the deviation period.

DATES: This deviation is effective from 12:01 a.m. on April 11, 2016 to 
11:59 p.m. on April 17, 2016.

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 April 11, 2016 to 11:59 p.m. on April 17, 2016, to 
allow the bridge owner to complete the necessary sand blasting and 
painting rehabilitation after unforeseen events have caused project 
delays. A containment scaffolding system has been installed below low 
steel of the entire length of the bridge structure, reducing vertical 
clearance for navigation by not more than 4 feet, and is 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

[[Page 19041]]

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: March 23, 2016.
D.H. Sulouff,
District Bridge Chief, Eleventh Coast Guard District.
