"Stretching an impressive 4.1 miles across the mouth of the Columbia River, the Astoria–Megler Bridge is the longest continuous truss bridge in North America. It connects the charming town of Astoria, Oregon, to the rugged shoreline of Megler, Washington, completing a vital link in U.S. Route 101. But this isn’t just a bridge, it’s a bold architectural statement standing guard over one of the most unpredictable waterways in the Pacific Northwest.

Each fall, the waters beneath the bridge come alive with one of nature’s great spectacles: the salmon runs. Hundreds of thousands of Chinook (King Salmon) and Coho surge upstream, navigating the powerful currents to reach their spawning grounds. Anglers line the banks and boats dot the channel, all hoping to intercept these muscular fish as they pass beneath the steel latticework above.

The Columbia River beneath the bridge is no gentle stream. It’s a deep, fast-moving artery that has claimed countless vessels over the centuries. The river’s mouth, just 14 miles downstream, is infamous for its shifting sandbars, powerful tides, and sudden squalls. Mariners call it the “Graveyard of the Pacific,” a name earned by the hundreds of sunken ships that litter its floor. Navigating this stretch requires precision, experience, and respect for the river’s many moods.

Among the modern giants that brave this treacherous passage is the Plumeria Leader, a Japanese-flagged cargo ship built in 2022 and operated by NYK Line. This roll-on/roll-off vehicle carrier spans over 200 meters and ferries thousands of cars and heavy machinery between North America and Japan. Watching it glide beneath the bridge’s steel canopy is like witnessing a ballet of brute force and finesse—its towering hull nearly brushing the trusses above, a visual reminder of the delicate choreography required to move global trade through this wild corridor.

Adding a touch of wild charm, thousands of double-crested cormorants have made the bridge their seasonal home, nesting in its steel beams and complicating inspections with guano and obscured lights. Once a year, the bridge opens to foot traffic for the Great Columbia Crossing, a six-mile run or walk that lets participants experience the thrill of crossing this engineering marvel on foot.

If you ever find yourself in Astoria, take a moment to gaze at its steel trusses and imagine the stories flowing beneath, from salmon and ships to storms and seabirds. The bridge doesn’t just span a river; it spans centuries of drama, resilience, and awe. It’s not just a crossing, it’s a living chapter in the Pacific Northwest’s epic tale."

"Visiting the Astoria-Megler Bridge in the pouring rain wasn't exactly planned but honestly, it ended up being one of the most memorable stops along the Oregon Coast that day. The bridge itself is absolutely stunning! Long, dramatic, and stretching across the Columbia River and on this day disappearing into the fog of the storm heading towards Washington. There's something special about seeing this iconic landmark in this moody and stormy atmosphere and watching as huge cargo ships being dwarfed by the size of the bridge as they steam off to their destinations. Catch some great views by the Bridgewater Bistro!"

"The Astoria–Megler Bridge is a stunning landmark and a must-see when visiting the Oregon Coast. Stretching over four miles across the Columbia River, it’s the longest continuous truss bridge in North America and an impressive sight in itself. The green steel structure contrasts beautifully with the blue waters below, making it a fantastic spot for photos.

From the Astoria waterfront, you can watch massive cargo ships and fishing vessels navigate the river, with the bridge creating a dramatic backdrop. The nearby Columbia River Maritime Museum adds to the experience, giving context to the river’s rich history. Whether you’re driving across, photographing it from the shore, or exploring the riverfront, the bridge offers iconic views and a real sense of scale."
