# SUPPLEMENTARY INFORMATION:

BNSF has requested that the BNSF Swing Bridge across the Columbia River remain closed to vessel traffic to facilitate maintenance of the train signaling system. BNSF will be “cutting over” the train signaling system to a new system on April 30, 2012. During this cut-over the swing span of the BNSF Railway Bridge across the Columbia River will be disabled and the bridge will not be able to be opened. The BNSF Bridge crosses the Columbia River, mile 105.6, and in accordance to NOAA Chart 18526 provides 39 feet of vertical clearance above Columbia River Datum 0.0 while in the closed position. Vessels which do not require a bridge opening may continue to transit beneath the bridge during this closure period. Under normal operation the bridge opens on signal as required by 33 CFR 117.5. This deviation period is from 8 a.m. on April 30, 2012 through 8 p.m. April 30, 2012. The deviation allows the swing span of the BNSF Railway Bridge across the Columbia River, mile 105.6, to remain in the closed position and need not open for maritime traffic from 8 a.m. through 8 p.m. on April 30, 2012. The swing span will be required to open, if needed, for vessels engaged in emergency response operations during this closure period. The bridge shall operate in accordance to 33 CFR 117.5 at all other times. Waterway usage on this stretch of the Columbia River includes vessels ranging from commercial tug and tow vessels to recreational pleasure craft including cabin cruisers and sailing vessels. Mariners will be notified and kept informed of the bridge's operational status via the Coast Guard Notice to Mariners publication and Broadcast Notice to Mariners as appropriate.

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: April 9, 2012.

Randall D. Overton,

Bridge Administrator.
