Description 

The original Sixth Street Bridge, a seven span wooden truss structure, was built in 1906 by F.W. Berndt and L.A. Heinz for $10,500. Most of the cost was covered by subscription of real estate developers, It survived flooding in November of that year when sand bagging kept the waters from lifting the structure off its piers.

McRae Brothers of Seattle began construction of the present Sixth Street bridge began in June 1930. The structure composed of five open spandrel concrete arches and six small approach spans is 677 feet in length and cost $85,153. Twelve concrete lampposts topped by ionic capitals line its railings. Governor Roland Hartley addressed a crowd of 3,000, including town founder Colonel William Prosserís widow and son, at the formal opening on May 6, 1931.
