US 97 - Biggs Rapids-Sam Hill Bridge - Painting - Complete November 2015

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.


How you benefit

Improves safety
The steel framework of the bridge was cleaned and repainted with a protective coating to prolong the life of this vital transportation connection.

The protective coating helps prevent future corrosion and preserves the bridge's structural integrity.

Economic incentive
Preserves a vital bi-state transportation connection, allowing it to continue handling commuter and freight traffic for years to come.
