30, 2010 and paints the steel beams above the roadway. - Crews
completed Phase 2 of the project in December 2010. This phase
cleaned and painted the piers in the Columbia River and bridge
towers on the Washington side. This project will clean and paint
the steel framework of the SR 433 Lewis and Clark Bridge. The
fresh coat of paint will help prevent future corrosion to the
steel, preserve the bridge’s structural integrity, and prolong
the life of the bridge. The Lewis and Clark Bridge is being
painted in three phases: Phase 1 cleaned and painted the Oregon
approach of the bridge structure, and was completed in February
2008. Phase 2 cleaned and painted the piers in the Columbia
River, and the bridge towers on the Washington side. This phase
began April 7, 2009, and was completed in December 2010. Phase 3
paints the superstructure of the bridge above the roadway. This
phase began June 30, 2010, and is expected to be complete by
fall, 2013. Why i
