SUPPLEMENTARY INFORMATION:

Washington State Department of Transportation (WSDOT) requested this deviation from normal operations of the dual First Avenue South bascule bridges in order to facilitate painting. The containment system for contaminants and other equipment must be modified or removed in order to operate the movable span. WSDOT has proposed to work on one leaf of the bascules at a time so that one side of the bridges may remain operable according to the normal operating regulations of the bridge. In this way, vessels that can safely pass one-leaf openings may continue to pass the bridge during the project. Other vessels need to provide five hours notice for opening both sides of the bascule spans from 6 a.m. on September 15 through 6 p.m. on November 11, 2003. The five hours minimum notice will enable the contractor to remove equipment, adjust rigging, and evacuate workers from the leaf. Currently, the draws need not open for the passage of vessels from 6 a.m. to 9 a.m. and from 3 p.m. to 6 p.m. Monday through Friday, except all Federal holidays but Columbus Day. Currently, the draws shall open at any time for vessels of 5000 gross tons and over, a vessel towing a vessel of 5000 gross tons and over, or a vessel proceeding to pick up for towing a vessel of 5000 gross tons and over. At other times the draws open on signal for the passage of vessels. Vessels on the related reach of the waterway should be able to provide at least five hours notice for double-leaf openings without unreasonable inconvenience. Traffic on the waterway includes container barges with regularly scheduled movements as well as sailboats, motor yachts, and tugboats. Large vessels of 5000 gross tons have not passed through the dual bridges in recent years. This deviation does not exempt these vessels from the five hours notice. The bridges when closed provide 32 feet of vertical clearance above mean high water for the central 100 feet of the drawspans.

In accordance with 33 CFR 117.35(c), this work will be performed with all due speed in order to return the bridge to normal operation as soon as possible. This deviation from the operating regulations is authorized under 33 CFR 117.35.
