Location

The current bridge is the second Vantage Bridge. The first was built in 1927 as part of the Sunset Highway (later US 10), a precursor to I-90. In 1962 the second bridge was built because the reservoir pool backing up behind the new Wanapum Dam would soon overwhelm the old bridge; it was dedicated by the state on November 9, 1962.[2] The first bridge was dismantled. In 1968 its steel cantilever truss was reused for the Lyons Ferry Bridge, where SR 261 crosses the Snake River.[3]
