Due to a crash at a railroad crossing, an overpass is to be constructed on an existing level highway. the existing highway has a design speed of 50 mi/h. The overpass structure is to be level, centered 26 feet above the railroad, and 180 feet long. How much existing highway (in feet) must be reconstructed to provide appropriate vertical alignment?
