Interstate 75 Interchange at Hamilton Place Mall

History and Background

The I-75 Interchange at Hamilton Place Mall (TDOT's portion of the project) includes:

• Grading, concrete paving, and drainage of two new interstate ramps with 16-foot lanes, 6-foot inside shoulders, and 8-foot outside shoulders;
• Three new bridges, including:
  • A new 225-foot, 2-span bridge over I-75,
  • A new 991-foot, 6-span bridge over the I-75 northbound exit ramp to Shallowford Road, and
    
  • A new 1,414-foot, 11-span bridge over the I-75 southbound entrance ramp from Shallowford Road;
• Nine new retaining walls;
• One new noise wall along the southbound side of I-75 at the north end of the project;
• Deck repair work on the existing ramp and Shallowford Rd. bridges over I-75;
• Concrete repair work along I-75;
• New signing, including six new overhead signs; and
  
• Interstate and ramp lighting.

The project along Hamilton Place Boulevard (the City of Chattanooga's portion of the project) will include:

• Grading, paving, and drainage of a multilane roadway with curb & gutter, 11-foot lanes, no shoulders, and 5-foot sidewalks along the east side of the roadway;
• Three signalized intersections;
• One new retaining wall; and
  
• Street-level lighting.

Due to the interconnected nature of the two projects, they were let to construction to the same contractor and will be administered by TDOT as a single project.
