The Washington State Department of Transportation has requested that the draw span of the SR 520 Bridge remain closed to vessel traffic to facilitate safe passage of participants of the Seafair Rock and Roll Marathon. The Rock and Roll Marathon is the largest distance running event in the Pacific Northwest. This event includes over 26,000 participants running a marathon (26.2 miles) or half marathon (13.1 miles). The race course passes over the SR 520 Lake Washington Bridge. The SR 520 Bridge provides three navigational openings for vessel passage, the movable floating span, subject to this closure, and two fixed navigational openings; one on the east end of the bridge and one on the west end. The fixed navigational opening on the east end of the bridge provides a horizontal clearance of 207 feet and a vertical clearance of 57 feet. The opening on the west end of the bridge provides a horizontal clearance of 206 feet and a vertical clearance of 44 feet. Vessels that are able to safely pass through the fixed navigational openings are allowed to do so during this closure period. Under normal conditions, during this time frame, the bridge operates in accordance with 33 CFR 117.1049(a) which states the bridge shall open on signal if at least two hours notice is given. This deviation period is from 10 a.m. on June 23, 2012 through 4 p.m. June 23, 2012. The deviation allows the floating draw span of the SR 520 Lake Washington Bridge to remain in the closed position and need not open for maritime traffic from 10 a.m. through 4 p.m. on June 23, 2012. The bridge shall operate in accordance to 33 CFR § 117.1049(a) at all other times. Waterway usage on the Lake Washington Ship ranges 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: June 8, 2012.
