SUPPLEMENTARY INFORMATION:

The Oregon Department of Transportation (ODOT) has requested that the upper deck of the Steel Bridge remain closed-to-navigation to accommodate the annual Bridge to Brews 8K and 10K run. The Steel Bridge crosses the Willamette River at mile 12.1 and is a double-deck lift bridge with a lower lift deck and an upper lift deck which operate independent of each other. When both decks are in the down position the bridge provides 26 feet of vertical clearance above Columbia River Datum 0.0. When the lower deck is in the up position the bridge provides 71 feet of vertical clearance above Columbia River Datum 0.0. This deviation does not affect the operating schedule of the lower deck which opens on signal. Under normal conditions the upper deck of the Steel Bridge operates in accordance with 33 CFR 117.897(c)(3)(ii) which states that from 8 a.m. to 5 p.m. Monday through Friday one hour advance notice shall be given for draw openings, and at all other times two hours advance notice shall be given to obtain an opening. This deviation period is from 8:45 a.m. until 10:40 a.m. on April 12, 2015. The deviation allows the upper deck of the Steel Bridge across the Willamette River, mile 12.1, to remain in the closed-to-navigation position and need not open for maritime traffic from 8:45 a.m. until 10:40 a.m. on April 12, 2015.

Vessels able to pass through the bridge in the closed positions may do so at anytime. The bridge will be able to open for emergencies 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. Waterway usage on this stretch of the Willamette River includes vessels ranging from commercial tug and barge to small pleasure craft.

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: March 23, 2015.

Steven M. Fischer,

Bridge Administrator, Thirteenth Coast Guard District.
