Major construction work is imminent for the South Carolina Dept. of Transportation’s (SCDOT) largest project in history, a $2.08-billion rebuild of a busy, clogged series of interstate interchanges in Columbia dubbed “malfunction junction.”
The Carolina Crossroads project will widen 14 miles of interstate and construct seven interchanges, including two interstate-to-interstate and five service road interchanges, according to Brian Klauk, SCDOT's project manager. A joint venture of Archer Western and United Infrastructure Group was awarded a contract for the project's first two phases, estimated at $335 million.
