The Washington State Department of Transportation, working in conjunction with the Oregon Department of Transportation, will accept sealed bids in mid-March for coatings work on the superstructure of the Lewis and Clark Bridge, an 8,288-foot-long cantilever structure over the Columbia River between Longview, WA, and Rainier, OR. The contract, which is jointly funded by the two agencies, is the third phase of a three-part effort to replace the coatings that were applied in 1984.
The contract includes cleaning and coating up to approximately 901,900 square feet of steel, including 671,600 square feet under the base bid and up to 230,300 more under four alternates. The majority of the steel will be abrasive blast-cleaned to SSPC-SP 10 (near white); 102,500 sq ft of stringers and expansion joint support beams will be cleaned with solvents (SSPC-SP 1) and compressed air. The project includes applying moisture-cured urethane and rust penetrating sealer systems to the steel. The contract requires containment of the existing coatings, which include lead, cadmium, and chromium hazardous materials.
