US 97 Biggs Rapids Bridge - Paint deterioration of steel truss
US 97 Biggs Rapids Bridge - deterioration of steel truss

The US 97 Biggs Rapids - Sam Hill Bridge is a two-lane steel truss bridge spanning the Columbia River between Maryhill, WA and Biggs Junction, OR.

It carries on average of 5,100 vehicles across the Columbia River every day, 26 percent of which are semi-trucks.  

Like a home, steel bridges have to be painted on a regular basis to protect them from the elements.

The Biggs Bridge was last painted in 1988. The protective coating on the bridge was deteriorating, exposing the steel to the weather and elements, which resulted in corrosion that left unpainted can weaken the structure over time.

Stripping old paint and rust and reapplying specialty bridge paint will protect the structure for approximately 20 years.
