Phase 3 for Lewis & Clark Bridge Work

Friday, September 3, 2010

Odyssey Contracting Corp., of Houston, PA, and Geronimo Painting Co. Inc., of Lisbon, OH, have begun the third and final phase in the complete repainting of the Lewis and Clark Bridge over the Columbia River.

Phase 3 work began June 30 on the 8,288-foot-long cantilever bridge, which spans the Columbia River between Longview, WA, and Rainier, OR. The bridge carries a heavy traffic load of 21,000 vehicles per day on average, including 13% freight.

The $33,774,714 contract, a shared responsibility of the Washington and Oregon Departments of Transportation, includes American Recovery & Reinvestment Act funding. This is the third phase of a three-part effort to replace the coatings that were applied in 1984.

Recoating Began in 2006

Abhe & Svoboda Inc. , of Prior Lake, MN, recoated about 14,236 tons of existing structural steel under the $14.6 million first-phase contract, which took place between August 2006 and February 2008.

Certified Coatings, of Concord, CA, is recoating substructure elements of the bridge, including in-river piers, under the $5.1 million second-phase contract, which began in April 2009 and is scheduled for completion this month.

The third phase, which will address the superstructure, is expected to be completed in fall 2013.

Scope of Work

The third phase involves recoating the cantilever truss superstructure, including the 1,200-foot-long main span, which reaches a height of 340 feet above the river. The majority of the steel will be abrasive blast-cleaned to a Near White finish (SSPC-SP 10), while select stringers and expansion joint beams will be cleaned with solvents and compressed air only.

The project includes recoating the steel with a moisture-cured urethane system, as well as applying a penetrating sealer to 4,300 linear feet of pack rust. The contract includes erecting containment structures to control the emission of the lead, cadmium, and chromium-bearing existing coatings.

All four contractors hold SSPC-QP 1 and QP 2 certifications.
