I85 Widening Project logo


The total cost including design, construction and inspection is approximately $480M.
The funds for the project include monies from federal and state gas taxes, the SC Transportation Infrastructure Bank, and specific funding from the South Carolina General Assembly.
The South Carolina Department of Transportation is the owner of this project and will have full-time staff members overseeing all aspects of construction.
Blythe Construction Company of Charlotte, NC and Zachry Construction of San Antonio, Texas have formed a joint venture (Blythe-Zachry) to build this project.
The construction is expected to last well into 2021.
The project includes:
  • rehabilitation of the existing 6 lane concrete portion from approximately mile marker 77 to mile marker 80
  • the construction of a new railroad bridge at mile marker 80.5
  • the widening to 3 lanes in each direction from mile maker 80 to mile marker 98
as well as interchange construction at numerous exits.
The construction of the interstate will accommodate the existing cemetery in the median of I 85 and will not encroach into it. In other words, the cemetery will remain as is.
