SUPPLEMENTARY INFORMATION: Caltrans requested a temporary change to the 
operation of the California Route 160 Drawbridge, mile 0.1, Three Mile 
Slough, 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 drawbridge opens on signal as required by 33 
CFR 117.5. Navigation on the waterway is commercial and recreational.
    The drawbridge will be secured in the closed-to-navigation position 
from 8 a.m. through 4 p.m. Monday through Friday, from October 15, 2009 
through November 4, 2009, to allow Caltrans to replace the industrial 
staircase leading to the control house. At all other times during this 
period the drawbridge will open on signal as required by 33 CFR 117.5. 
This temporary deviation has been coordinated with commercial and 
recreational waterway users. There is no anticipated levee maintenance 
during this deviation period. No objections to the proposed temporary 
deviation were raised.
    Vessels that can transit the drawbridge, while in the closed-to-
navigation position, may continue to do so at any time.
    In the event of an emergency the drawbridge can be opened with 4 
hours advance notice.
    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: October 01, 2009.
S.P. Metruck,
Captain, U.S. Coast Guard, Acting Commander, Eleventh Coast Guard 
District.
