SUPPLEMENTARY INFORMATION: Back to Top

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.

District Bridge Chief, Eleventh Coast Guard District.
