Project OverviewDescripción del proyecto
Emery Sapp & Sons was chosen as the Design-Builder to construct a 4-lane arterial roadway project to help drive economic development in the corridor between east and west Liberty, MO. The South Liberty Parkway Project extended south of Liberty Parkway from Withers Roads to Highway 291 passing through previously undeveloped real estate primarily to be used for small farming operations. As the Design-Builder, ESS was challenged to develop an early GMP to fast-track the project schedule to accommodate all stakeholders including adjacent landowners, Union Pacific Railroad (UPRR), Central Pacific Railway (CPRR), and BNSF Railway.
The project included the construction of two bridges, one of which utilized a girder launching technique. The first bridge that spans over the Union Pacific/Central Pacific railway was a 188-foot two-span precast bridge with NU girders and a 65-foot wide deck, while the second was a 703′ six-span bridge with NU girders and a 65-wide deck over the BNSF railway and Little Shoal Creek. Overall the project included 750,000 cubic yards of excavation and grading, 80,285 square yards of Type 5 base rock, 6,000 linear feet of storm sewer, 36 storm sewer structures, 18,000 linear feet of 16″ water line, and 5,000 linear feet of 12″ water line. Furthermore, the project includes a pedestrian path, 65,000 square yards of 10″ asphalt pavement, 3,500 square yards of 12″ MoDOT Superpave asphalt, two 12×12 concrete reinforced concrete boxes (RCB), 63,000 square feet of sidewalks, and two new traffic signals at Withers and MO-291.
