I-26 Widening MM 85 – 101 Project

The project includes widening I-26 from 4 to 6 lanes for approximately 12 miles and from 4 to 8 lanes for approximately 4 miles. Interchange improvements are anticipated at Exit 97 (US 176), Exit 91 (S-48 Columbia Ave.), and Exit 85 (SC 202). Overpass bridge replacements are anticipated at S-58 (Koon Road), S-80 (Shady Grove Road), S-234 (Mt. Vernon Church Road), S-405 (Old Hilton Road), S-49 (Peak Street), S-39 (Peak Road), and S-167 (Parr Road). The project website is at https://scdotmidlandsconnection.com/.
