Toutle River Bridge
Hello to you. Do you know what happen on May 18, 1980? That is lucky bridge over Toutle River. Because of lahar and hot water from Mount St. Helens Volcano Eruption. Lahar or hot water of lava were damage two camelback truss on highway state route 504 and railroad bridge near freeway I-5 and other bridges near Mount St. Helens. They check bridge is safety. THANK YOU
