SUPPLEMENTARY INFORMATION:

Oregon Department of Transportation (ODOT) owns the Youngs Bay Bridge across Youngs Bay, mile 0.7, Old Youngs Bay Bridge across Youngs Bay, mile 2.4, foot of Fifth Street, and the Lewis and Clark River Bridge across the Lewis and Clark River, mile 1.0. ODOT has requested this temporary deviation from the operating schedule while a rule change is being reviewed for approval. The three subject bridges are within one mile of each other, and currently open on signal for the passage of vessels with one half-hour notice by marine radio, telephone, or other suitable means. These three bridges are operated by the Lewis and Clark River bridge operator in accordance with 33 CFR 117.899.

This deviation will allow ODOT to operate without a bridge operator attending the three subject bridges until an opening request has been received. This deviation authorizes ODOT's bridge operator to open the subject bridges within two hours after receiving a request for an opening from 5 p.m. on Friday to 7 a.m. on Monday, including all Federal holidays, starting at 7 a.m. on September 22, 2018, through 7 a.m. on March 19, 2019. The Youngs Bay Bridge provides a vertical clearance approximately 37 feet above mean high water when in the closed-to-navigation position. The Old Youngs Bay Bridge provides a vertical clearance approximately 19 feet above mean high water when in the closed-to-navigation position. The Lewis and Clark River Bridge provides a vertical clearance of 17 feet above mean high water when in the closed-to-navigation position. Vessels operating on Youngs Bay and the Lewis and Clark River range from small recreational vessels, sailboats, tribal fishing boats and small commercial fishing vessels.

Vessels able to pass through the subject bridges in the closed-to-navigation position may do so at any time. The bridges will not be able to open for emergencies from 5 p.m. on Friday to 7 a.m. on Monday unless a two hour notice is given, and there is no immediate alternate route for vessels to pass. The Coast Guard will inform the users of the waterway, through our Local and Broadcast Notices to Mariners, of the change in operating schedule for the bridge so that vessel operators can arrange their transits to minimize any impact caused by the temporary deviation.

In accordance with 33 CFR 117.35(e), the drawbridges must return to their 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.
