Echoes on the Cowlitz: The 1923 Kelso Bridge Collapse

On January 3, 1923, an evening commute turned into Washington state's deadliest bridge collapse when the creaking, overloaded Allen Street Bridge plunged into the raging Cowlitz River. Battered by torrential winter floods and a massive upstream logjam, the rotting wooden span snapped under the weight of bumper to bumper traffic, sending cars, horse teams, and over a hundred workers straight into near freezing waters. The disaster claimed dozens of lives, many of them transient laborers whose bodies were swallowed by shifting river silt and never recovered. More than a century later, the exact death toll remains an unsolved mystery, leaving behind a tragic legacy of boomtown negligence and haunting Pacific Northwest river lore.
