The Lake Washington Ship Canal Bridge is a six span complex under-deck truss bridge with two levels of traffic. The total length of the bridge is 2,274 feet. Five of the spans are approximately 350 feet long, and the main span is just over 550 feet in length. The lower deck on the main span is 140 feet above the water.

The project required lead-based paint to be removed by SSPC-SP7 brush-off blasting with SSPC-SP 6 spot abrasive blasting in heavily corroded areas. The entire structure was over-coated with a Wasser High Tech Coatings moisture cure polyurethane system.

Only one lane of traffic was permitted to be closed during the blasting and painting operations. The average daily traffic across the bridge was 285,450 vehicles per day.
