WILIIIMI C. BIP PE. <br />CO STAUCr AL EN <br />S November 2006 <br />Mr. Adam Vega <br />Wildcat Mining <br />(970) , Fax: (970) <br />Pe: Bridge for Wildcat Minims. La Plata Canyon. La Plata County. Colorado <br />(Project 92696). <br />Dear Mr. Vega. <br />#2696 <br />At your request I evaluated this bridge. This bridge is approximately 36 feet long by 11 <br />feet wide with four 12"x12" beams. Bridge supports are approximately 33 feet on taster. <br />In my opinion this bridge is capable of supporting an AASHTO truck loading type HI <br />44 which is 6.000 pounds on the front a+cic and 24.000 pounds on the rear axle spaced 14 <br />feet on center. <br />We will be glad to evaluate any other potential loading due to another vehicle that you <br />may desire to use in your endeavor. <br />Feel free to call any time regarding this letter or if you have any further questions. <br />WCB/bb <br />ec File <br />William C.
