SUPPLEMENTARY INFORMATION:

California Department of Transportation has requested a temporary change to the operation of the California Department of Transportation highway drawbridge across the Mokelumne River, mile 3.0, at East Isleton, CA. The drawbridge navigation span provides approximately 7 feet vertical clearance above Mean High Water in the closed-to-navigation position. In accordance with 33 CFR 117.175(a), the draw opens on signal from November 1 through April 30 from 9 a.m. to 5 p.m.; and from May 1 through October 31 from 6 a.m. to 10 p.m., except that during the following periods the draw need only open for recreational vessels on the hour, 20 minutes past the hour, and 40 minutes past the hour: Saturdays, 10 a.m. until 2 p.m.; Sundays, 11 a.m. until 6 p.m.; and Memorial Day, Fourth of July and Labor Day 11 a.m. until 6 p.m. At all other times the drawbridge shall open on signal if at least 4 hours notice is given. Navigation on the waterway is commercial and recreational.

The drawspan will be secured in the closed-to-navigation position from 5 a.m. on March 2, 2015 to 10 p.m. on May 29, 2015, due to replacement of bridge deck and rehabilitation of the bridge control house. This temporary deviation has been coordinated with the waterway users. Caltrans work plan and dates have been tailored to produce the least possible impacts to waterway traffic, land traffic, businesses and potential flood response plans, while allowing the work to be performed, to ensure dependable future operation of the drawbridge. Vessels able to pass through the drawbridge in the closed position may do so at any time. The drawbridge will not be able to open for emergencies. Alternative paths for recreational vessel traffic are available via Little Potato Slough and Georgiana Slough. Alternative paths for land traffic are also available. The Coast Guard will inform waterway users of this temporary deviation via our Local and Broadcast Notices to Mariners, to minimize resulting navigational impacts.

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: February 27, 2015.

District Bridge Chief, Eleventh Coast Guard District.
