This is a temporary bridge built to get across a small creek, which can't have equipment running in it. It was designed and built in 2 weeks, at a cost of $750,000 (I think). It's built from steel H-beams and what looked to be 12-by-12's. It's 40 feet wide and can accomodate the weight of a scraper, the biggest piece of equipment working on this fill. The metal in the front of the pictures are sheet piles, pieces of metal hammered into the ground which create a barrier that makes sure no groundwater seeps into an excavation.
