SUPPLEMENTARY INFORMATION: The California Department of Transportation 
has requested a temporary change to the operation of the Isleton 
Drawbridge, mile 18.7, over Sacramento River, at Isleton, CA. The 
drawbridge navigation span provides a vertical clearance of 15 feet 
above Mean High Water in the closed-to-navigation position. The draw 
opens on signal from May 1 through October 31 from 6 a.m. to 10 p.m. 
and from November 1 through April 30 from 9 a.m. to 5 p.m. At all other 
times the draw shall open on signal if at least four hours notice is 
given to the drawtender at the Rio Vista bridge across the Sacramento 
River, mile 12.8, as required by 33 CFR 117.189(a). Navigation on the 
waterway is commercial and recreational.
    Either leaf of the double bascule drawspan may be secured in the 
closed-to-navigation position from 7 a.m., April 20, 2012 to 6 p.m. on 
June 18, 2012, to allow Caltrans to conduct painting and maintenance on 
the bridge. The opposite leaf will continue to operate normally, 
providing unlimited vertical clearance and 83 feet horizontal clearance 
between leafs. A work platform will be installed below the secured 
leaf, reducing vertical clearance by 6 feet. This temporary deviation 
has been coordinated with waterway users. No objections to the proposed 
temporary deviation were raised.
    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: March 23, 2102.
D.H. Sulouff,
District Bridge Chief, Eleventh Coast Guard District.
