The Big Shanty Connector provides an additional multi-lane connector under I-75 in the Chastain Road/Barrett Parkway area of Cobb County. This project greatly increases the connectivity between Kennesaw State University (KSU) and Town Center Mall, two major Regional Activity Centers. Additionally, the connector provides congestion relief to the existing interchanges on I-75 at both Barrett Parkway and Chastain Road.
