Caltrans requested a temporary change to the operation of the Rio Vista Drawbridge, mile 12.8, Sacramento River, at Rio Vista, CA. The Rio Vista Drawbridge navigation span provides a vertical clearance of 17 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 consists of both commercial and recreational vessels.

The 4-hour notice for openings during the maintenance period, between 9 p.m. and 5 a.m., from October 22, 2007 through December 19, 2007, will allow Caltrans to clear the drawspan of maintenance equipment so as not to delay approaching vessels. This temporary deviation has been coordinated with all affected waterway users. 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 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.
