Multnomah County has requested that the Hawthorne lift bridge remain closed to vessel traffic to facilitate safe, uninterrupted roadway passage of participants of the Rock-n-Roll Half Marathon event. The Hawthorne Bridge crosses the Willamette River at mile 13.1 and provides 49 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 conditions this bridge operates in accordance with 33 CFR § 117.897 which allows for the bridge to remain closed between 7 a.m. and 9 a.m. and 4 p.m. and 6 p.m. Monday through Friday. This deviation period is from 4 a.m. on May 20, 2012 through 10 a.m. May 20, 2012. The deviation allows the Hawthorne Bridge across the Willamette River, mile 13.1, to remain in the closed position and need not open for maritime traffic from 4 a.m. through 10 a.m. on May 20, 2012. The bridge shall operate in accordance to 33 CFR 117.897 at all other times. Waterway usage on this stretch of the Willamette River includes vessels ranging from commercial tug and barge to small pleasure craft. 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. The draw span will be required to open, if needed, for vessels engaged in emergency response operations during this closure period.

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 24, 2012.

Bridge Administrator.
