The middle 3 spans <br />were originally a sing(e polygonal warren iruss span. The truss was rendered nonfunctionaJ by adding steel <br />piling under 2 of the 5 intermediate truss floorbeams and by replacing the original iruss stringers with larger <br />stringers capable of spanning between the supported floorbeams. The original approach spans had a length of <br />approximately 24 ft. These spans were replaced with longer spans supported on new steel pile abutments located <br />behind the original timber pile abutments that were faiiing. <br />The existing bridge was built in 1993. Details of the original truss suggest that it was fabricated between 19 10 <br />and 1935. The bridge is on a 01 skew. The bridge is posted for a Weight Limit of 17500 Ibs Axie or Tandem <br />(Sign R12-2Tb). <br />The existing bridge is to be replaced. Since proposals are being considered to preserve the original truss, the <br />focus of this report is on the conditian ofthe origina► truss and its suitahi(ity for rehabilitation. <br />~1~ <br />
