SUPPLEMENTARY INFORMATION:

The California Department of Transportation has requested a temporary change to the operation of the Rio Vista Drawbridge, mile 12.8, over Sacramento River, at Rio Vista, CA. The drawbridge navigation span provides a vertical clearance of 18 feet above Mean High Water in the closed-to-navigation position. In accordance with 33 CFR 117.5, the draw opens on signal. Navigation on the waterway is commercial, search and rescue, law enforcement, and recreational.

The drawspan will require a one hour advance notice at three specified periods: (1) From 7 p.m. on June 16, 2017 to 4 a.m. on June 17, 2017; (2) from 8 p.m. on June 24, 2017 to 7 a.m. on June 25, 2017; and (3) from 7 p.m. on June 30, 2017 to 4 a.m. on July 1, 2017, to allow the bridge owner to make emergency repairs to the bridge deck. A one hour advance notice will give enough time for the contractor to clear away equipment and workers before the drawspan can safely open for transiting vessels. Scaffolding will be installed below the bridge deck from June 16, 2017 through July 1, 2017, reducing the vertical clearance by 4 feet, and will extend from the west tower 48 feet into the navigational channel. This temporary deviation has been coordinated with the waterway users. Start Printed Page 27424No objections to the proposed temporary deviation were raised.

Vessels able to pass through the bridge in the closed position may do so at anytime. The bridge will be able to open for emergencies with one hour advance notice. There is no immediate alternate route for vessels to pass. The Coast Guard will also inform the users of the waterway through our Local and Broadcast Notices to Mariners of the change in operating schedule for the bridge so vessel operators can arrange their transits to minimize any impact caused by the temporary deviation.

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.
