Sugar Creek Road Grade Separation

Mecklenburg County, North Carolina

KCI served as the structural engineer for the grade separation project (NCDOT TIP U-5008) on Sugar Creek Road at Norfolk Southern Railroad. This project converted an existing at-grade crossing to a grade separation to accommodate the construction of The Charlotte Area Transit System’s (CATS) Light Rail Extension Project.

Our team provided preliminary design including developing structure alternatives. KCI also provided final bridge design including structure construction plans and project special provisions. The bridge is an eight-span, horizontally curved, pre-stressed concrete structure with MSE walls at the end bents. It has an overall length of 846 feet and a width of 71’-1” to accommodate four traffic lanes and two sidewalks. The bridge spans over two existing Norfolk Southern rail lines, two future Norfolk Southern rail lines, two CATS light rail lines and two surface streets.

This project was unique because we had to design virtually every single member of the structure individually because of the aesthetic features, railroad crossing and other site constraints.

Due to State Historic Preservation Office (SHPO) requirements, aesthetic treatments were required on this structure, including black anodized two-bar metal rail, black vinyl coated chain link pedestrian fence over the Norfolk Southern rail lines, bridge and wall mounted street lighting, form-lined square columns adjacent to the surface streets, and a three dimensional prism pattern on the MSE walls.
