I-85 Reconstruction & Widening Design-Build

Spartanburg & Cherokee Counties, SC

Parrish & Partners is serving as the lead design engineering firm for this design-build project, which consists of reconstruction and widening approximately 21 miles of I-85 in Spartanburg and Cherokee Counties. The project will reconstruct the existing asphalt pavement to Portland Cement Concrete, increase capacity, and upgrade interchanges and overpass bridges to meet state and federal design requirements. SCDOT intends to reconstruct the existing six lanes and auxiliary lanes from the pavement joint near MM 76.4 to MM 80, then widen I-85 from four to six lanes beginning at MM 80 in Spartanburg County and ending at the Broad River Bridge.
