Andrews Bypass, Phase II
CALYX is providing transportation design, surveying, SUE, and environmental services on this 3.5-mile, four-lane divided highway on new location. CALYX will prepare an Environmental Assessment based on NEPA guidelines. CALYX will also prepare right-of-way acquisition plans and construction documents. The project corridor will cross floodplains and Johnson’s Swamp, and will require the design of one or two bridges. CALYX developed design year build and no-build peak hour traffic volumes and analyzed existing and future traffic conditions to demonstrate the proposed project would meet the intended purpose and need as well as to determine specific intersection configurations along the route. The new roadway will connect to the completed Phase I project and serve as the southwest bypass around Andrews, SC.
