Interstate 24 Interchanges at Broad and Market Streets

Project Map

Design

The existing design along I-24 East at Exit 178 consists of a series of loops and ramps that connect the interstate with US 27, as well as a Broad, Williams, and Market Streets.

The planned design will replace the existing loops and ramps that currently serve I-24 East and US 27 with a new, single ramp, serving exiting traffic from both I-24 East and US 27 South.
The new ramp will be constructed on the south side of I-24, west of the I-24/US 27 interchange, between the old Wheland Foundry site and the Tennessee River. It will bridge over Chestnut Street and the Riverwalk at the old foundry site.

The new ramp will transition to a frontage road that will run parallel to I-24. The frontage road will provide access to Broad Street, Williams Street, and Market Street at signalized intersections.
Traffic entering I-24 East from the south side of the city will use the frontage road to access the interstate on a newly constructed on-ramp near Howard School.

Additional points of interest are noted below.

• Williams Street will be altered to accommodate two-way traffic.
  
• Long Street will be closed to all vehicle traffic. A cul-de-sac will be constructed to provide access to homes and businesses near the 25th Street intersection.
  
• 26th Street will not be affected by the new facility.
  
• Howard School traffic will maintain access to Market Street and I-24.
  
• Existing loops and ramps serving I-24 West and US 27 North, located north of I-24 in the same area, will have only minor adjustments. Traffic flow will not be impacted.

Construction also includes grading, drainage, and paving throughout the project limits, as well as the addition of bridges, retaining walls, signals, and lighting.
