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 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. through 4:30 p.m. Monday through Friday, from August 31, 
2009 through September 14, 2009, to allow Caltrans to replace the 
industrial staircase leading to the control house. At all other times 
during this period, and on September 7, 2009, Labor Day, the drawspan 
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 bridge, while in the closed-to-
navigation position, may continue to do so at any time.
    In the event of an emergency the drawspan 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: August 28, 2009.
J.R. Castillo,
Rear Admiral, U.S. Coast Guard Commander, Eleventh Coast Guard 
District.
