Most newer concrete beams that hold up Utah highway bridges are around 145 feet long. But the Utah Department of Transportation is about to place six that are 40 percent longer — 203 feet — to help widen Interstate 15 in Lehi.
They are longer than the iconic Cinderella’s castle in Walt Disney World (189 feet) is high, or the leaning tower of Pisa (185 feet).
They also will be the third-longest, single-component beams in the United States, slightly shorter than two in Orlando, Fla., and Seattle, said Lee Wegner, with Forterra Structural Precast, the West Valley City company that is making them.
