Multnomah County, the bridge owner, requested the Broadway Bridge be authorized to open half the span in single leaf mode to make adjustments to newly installed equipment. The Broadway Bridge crosses the Willamette River at mile 11.7, and provides 90 feet of vertical clearance above Columbia Start Printed Page 4144River Datum 0.0 while in the closed-to-navigation position, and provides 125 feet of horizontal clearance with half the span open. This bridge operates in accordance with 33 CFR 117.897. This deviation allows the double bascule span of the Broadway Bridge across the Willamette River, mile 11.7, to operate the bridge in single leaf mode to marine traffic. The deviation period will be from 1 a.m. on January 27, 2018 to 11:59 p.m. on February 23, 2018. The bridge shall operate in accordance to 33 CFR 117.897 at all other times.

Waterway usage on this part of the Willamette River includes vessels ranging from commercial tug and barge to small pleasure craft. One particular shipping company regularly requests a full bridge span opening in order to transit the river. In anticipation of this deviation, the shipping company has agreed to give a 7 day notice and a 24 hour notice to the bridge owner for a request of a full bridge span opening. If this procedure is followed, the bridge owner has agreed to comply with these requests.

Vessels able to pass through the bridge in the closed-to-navigation position 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.

In accordance with 33 CFR 117.35(e), the drawbridge must return to its 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.
