The Highway 104 Hood Canal Bridge will be closed for a minimum of four nights starting Monday, May 7 so repairs can be made to portions of the west-half draw span, according to the Washington State Department of Transportation.

Closures are scheduled from 8:45 to 10:45 p.m., 11 p.m. to 1 a.m., and 1:15 to 3:45 a.m. There will be three, 15-minute intervals for vehicles to cross the bridge.

Officials said the work is weather-dependent, and will carry over to the following weeks, if necessary, until completed.

DOT officials said divots are appearing in the 1.5-inch thick steel plates that run the length of the wet-half draw span, making it increasingly difficult to open the west half of the bridge. The plates protect the pontoon’s concrete from 4-foot diameter steel rollers, which guide the draw span as it opens and closes.

The repairs must be made with the draw span open and involve welding low spots in the guide-roller rails.
