SUPPLEMENTARY INFORMATION:

Union Pacific Railroad Company (UPRR) has requested a temporary deviation from the operating schedule for the Steel Bridge across the Willamette River, at mile 12.1, at Portland, OR. The deviation is necessary to accommodate participates in the Starlight Parade and Rose Parade events and mass transit vehicles. The Steel Bridge is a double-deck lift bridge with a lower lift deck and an upper lift deck which operate independent of each other. To facilitate this event, the upper deck will remain in closed-to-navigation position. When the lower deck is in the closed-to-navigation position, the bridge provides 26 feet of vertical clearance above Columbia River Datum 0.0; and in open-to-navigation position, the vertical clearance is 71 feet above Columbia River Datum 0.0. The deviation period is from 7 p.m. to 11:30 p.m. on June 3, 2017, and from 7 a.m. to 1 p.m. on June 10, 2017. The lower deck for the Steel Bridge will operate in accordance with 33 CFR 117.897(c)(3)(ii), and at all times outside the specified deviation period, the upper deck of the Steel Bridge will operate in accordance with 33 CFR 117.897(c)(3)(ii).

Waterway usage on this part of the Willamette River includes vessels ranging from commercial tug and barge to small pleasure craft. Vessels able to pass through the bridge with the lower deck in the open-to-navigation position or upper deck in the closed-to-navigation position may do so at any time. The bridge will be able to open for emergencies, and there is no immediate alternate route for vessels to pass. The Coast Guard has conducted a public outreach for this closure of the upper deck on the Steel Bridge to known mariners that transit on the river. The Coast Guard has not received any objections to this temporary deviation from the operating schedule. 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 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 designated time period. This deviation from the operating regulations is authorized under 33 CFR 117.35.

Dated: May 9, 2017.

Bridge Administrator, Thirteenth Coast Guard District.
