Inquiry (采购产品): bridge beams I need to build a bridge across a creek before I can build a house. The span will be about 45 feet. I am looking at putting up two beams and placing wood ontop of the beams to drive across. Do you have recommendations for the size and strength of the beams. Would also like a quote for two beams. **** Hidden Message ***** Darby Gibson 38478 Company: personal E-mail: dgibson@igiles.net **** Hidden Message ***** dgibson@igiles.net
