Astoria–Megler Bridge

The Astoria-Megler Bridge spans 6,545 meters across the Columbia River, connecting Oregon and Washington states with a continuous steel truss structure.

Construction began in November 1962, with concrete piers cast at Tongue Point and steel segments manufactured in Vancouver before transportation downstream for assembly.

The Great Columbia Crossing event transforms the bridge into a pedestrian pathway once per year, allowing people to walk across the Columbia River.

The bridge carries two lanes of US Route 101 traffic and accommodates bicycles, supporting wind gusts up to 240 kilometers per hour.

The bridge features a 752-meter cantilever section near the Oregon side, making it North America's longest continuous truss bridge.
