STH 50 was an urban modernization and major reconstruction project, one of the largest in the Southeast Region’s history. The 4.5-mile corridor expanded the existing four-lane highway west of 57th Avenue to a six-lane facility. The remainder of the corridor, east of 57th Avenue, was reconstructed using the existing four-lane highway.
Six bridges on STH 50 were reconstructed and widened over the Canadian Pacific railroad, Union Pacific railroad, and 77th Avenue along with constructing seven MSE walls, six modular walls, and various temporary walls. The project also constructed highly environmental elements, including sensitive waterways, ponds, and two jack and bore pipes within a low-lying watershed region. Constant utility coordination was required to keep this aggressively scheduled project on track, and the construction team employed many temporary and permanent work revisions as a result. The project included over 600,000 cubic yards of earthwork, over 1,200 storm sewer structures, 74,000 feet of pipe, eight signalized intersections, eight sign structures, 340,000 square yards of concrete pavement, and 512,000 square feet of sidewalk.
