1. 18th St. Bridge Marker
Lewiston's first bridge across the Clearwater River was constructed in 1913 and replaced in 1951.
Early efforts for a bridge were opposed by ferryboat owners, but other business leaders recognized the need for a link to northern communities. Spanning 780 feet, its steel girders and railings were painted green and red. The wooden deck was 19 feet wide to accommodate large wagons. Automobiles and heavy trucks soon challenged the design.
Erected by Nez Perce County Historical Society, Idaho State Historical Society, Idaho Transportation Department. (Marker Number 501.)
