Everyone. This portion of I-75 currently carries up to 174,000 vehicles per day, which includes residents, commuters, carpoolers, local businesses, intrastate and interstate commercial vehicles, and tourists.

Improving this aging segment of freeway infrastructure will increase safety and provide an improved driving surface and experience.
