Snake River Bridge, Steel cantilever bridge in Franklin County, United States

The Snake River Bridge carries State Route 261 across the Snake River at its confluence with the Palouse River near Starbuck, Washington. It is the oldest surviving steel cantilever truss bridge in the state, listed on the National Register of Historic Places in 1982 under number 82004207. It stands beside Lyons Ferry State Park and the Joso railroad bridge.

Built between 1926 and 1927 as the Vantage Ferry Bridge, it carried the North Central Highway over the Columbia River at Vantage, replacing a four-car ferry that had moved 50,000 people a year by 1923. Governor Louis F. Hart blocked a proposed private toll bridge, saving $900,000 in federal highway funds. When the Wanapum Dam flooded Vantage in the 1960s, the span was dismantled and stored, then rebuilt at Lyons Ferry, where the Lower Monumental Dam had slowed the river and lengthened ferry crossings. It reopened to traffic in 1968.

The bridge is also called the Lyons Ferry Bridge, after the ferry crossing it replaced; the crossing was still by ferry until the Lower Monumental Dam slowed the Snake River and lengthened the trip. The stored Vantage span was re-erected here and opened to traffic in 1968, beside Lyons Ferry State Park and the Joso railroad bridge.

The bridge carries State Route 261 across the Snake River at its confluence with the Palouse River, near Starbuck. It stands beside Lyons Ferry State Park, and the Joso railroad bridge is nearby. Approaching from either direction, drivers cross the river on the same two-lane roadway that was re-erected here in 1968.

The bridge is the oldest surviving steel cantilever truss bridge in Washington State. It was dismantled at Vantage, stored, and rebuilt here, opening to traffic in 1968.
