SUBJECT: Exit 49 Corridor Traffic Signal Retiming 
 
Summary 
The FY25 budget includes $62,000 for an engineering firm to develop a signal timing plan for five  
intersections along the Decatur Pike Corridor at Exit 49.  The recent addition of new signal equipment at 
the I-75 ramps, as well as continued growth in the area, has created the need for a new timing program 
for this corridor.  The intersections to be included are: 
• Lee Irwin Road 
• Holiday Drive 
• I-75 North Bound Ramps 
• I-75 South Bound Ramps 
• Denso Drive/Milton Road 
 
All but the Lee Irwin Road intersections currently have a traffic signal in place.  Lee Irwin is being included 
in the study because several developments have been proposed for the property around this intersection 
and if they are ever constructed a traffic signal will be needed.  By including it in the study, we will already 
have the timing data to input rather than having to conduct another study solely for this intersection. 
 
Given their extensive experience with signal timing projects throughout the State of Tennessee and the 
correlation between this intersection and the results of the Traffic Safety Action Plan, PW has elected to 
negotiate a services agreement with Kimley Horn and Associates rather than issue an RFQ.  Tennessee 
purchasing law does not require an RFQ for professional services on new projects when you negotiate an 
agreement with a firm with which you already have contracted for other projects.   The attached 
agreement calls for Kimley Horn to complete the desired scope of work for a lump sum fee of $34,600 .  
Kimley Horn is to complete the design work by June 30, 2025. 
 
The Department plans to request funding in the FY26 budget for the implementation  of the plan that 
would be developed if this agreement is approved.  The implementation will involve the purchase of new 
equipment and programming of both the existing and new equipment.
