SUPPLEMENTARY INFORMATION:

BNSF requested that the BNSF Swing Bridge across the Columbia River, mile 105.6, remain closed to marine vessel traffic to install new swing gears, shafts and bearings. During this installation period, the swing span of the bridge will be in the closed-to-navigation position. The BNSF Swing Bridge, mile 105.6, provides 39 feet of vertical clearance above Columbia River Datum 0.0 while in the closed position.

The subject bridge operates in accordance with 33 CFR 117.5. This deviation allows the swing span of the BNSF Railway Bridge across the Columbia River, mile 105.6, to remain in the closed-to-navigation position, and need not open for maritime traffic from 8 a.m. to 3 p.m. on December 27, 2017. The bridge shall operate in accordance to 33 CFR 117.5 at all other times. Waterway usage on this part of the Columbia River includes vessels ranging from large ships to commercial tug and tow vessels to recreational pleasure craft including cabin cruisers and sailing vessels. Vessels able to pass through the bridge in the closed-to-navigation position may do so at any time. The bridge will not be able to open for emergencies during this closure period, and there is no immediate alternate route for vessels to pass. The Coast Guard will also inform the users of the waterways through our Local and Broadcast Notices to Mariners of the change in operating schedule for the bridge so that vessels 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 designated time period. This deviation from the operating regulations is authorized under 33 CFR 117.35.

Dated: December 21, 2017.

Bridge Administrator, Thirteenth Coast Guard District.
