Sonoma County, California Bridges: Copeland Crossing over the Petaluma River
August 2014 (38.2389 Degrees, -122.6398 Degrees) Copeland Crossing
A couple of blocks upstream from yesterday's bridge is another bowstring truss, only made of steel instead of timber. The Copeland Crossing is a prefabricated pony truss bridge built of Corten steel, designed by CSW/ST2, and built by the Excel Bridge Manufacturing Company. The bridge was manufactured in two 71 ft long pieces, brought to the site, set into position with four cranes, and then bolted together. Because of the weak soil the abutments were placed on deep piles and surrounded with Geofoam blocks. The bridge was designed to match the Balshaw Bridge and it was completed last summer. It connects the two sides of the Petaluma River Trail.
