Project Overview

The $168 million final phase of the I-75 Modernization Project will improve safety, decrease congestion, and provide much-needed updates to the more than 50-year-old highway between the intersections of I-75 and Route 4 and I-75 and U.S. 35. The project is expected to be completed in fall 2017. I-75 between Main and Fifth streets will be completely reconstructed. The project includes:

  • removal of left-hand entrances and exits, replaced by one primary ramp to access downtown;
  • creation of three continuous lanes in both directions from Third to Main streets and upgrading of pavement conditions;
  • total reconstruction of 12 bridges;
  • creation of one central interchange in the area of First and Third streets; and
  • the realignment of surface streets to coordinate with revised interstate entrances and exits.


In these renderings of the completed I-75 through downtown, notice the new green space created along the river and larger, easier-to-access exit and entrance ramps at Third Street.
