Preliminary engineering included schematic design for the new location bypass freeway, preliminary drainage analysis, large signing and illumination schematics, and public involvement which included participation in public meetings and a public hearing. Our team also coordinated schematic design with development of the project’s environmental assessment, which included evaluating wetlands and floodplains along the project corridor and modifying design to reduce impacts. Final design included preparing PS&E for the 6.4-mile corridor which included 19 bridges located at US 287, Union Springs Road, two Union Pacific Railroad crossings (with Exhibit A approval), Dry Creek, Bear Creek, Bear Creek Tributary, and numerous drainage outfalls. Our team developed horizontal and vertical roadway geometry for the mainlanes, ramps and intersecting roadways; prepared the multi-phased traffic control plan; and developed the design cross sections.
