Bridge Washing in Unincorporated King County
Crews use different washing tools to meet the needs of each bridge and comply with Washington Department of Ecology and Washington Department of Fish and Wildlife Permits. Here, crews used a hand-held washer cleaning the lower levels of the Green River Gorge Bridge located to the west of Black Diamond, WA in 2019. After dry cleaning, crews wash with the minimum water pressure necessary to accomplish the work and prevent the removal of existing paint and subsequent discharge to waters of the state.
Overview
Bridges must be regularly cleaned in order to extend their useful life and ensure they perform safely. Bridges can become dirty from sand, dirt, gravel, pollution, and anti-icing chemicals, which can fade paint and eat away at steel.
