Bullitt County: I-65 at KY 480 Interchange Improvements - Project 05-391.3

​​ky 480 dcd.PNG

​
Purpose
Improve traffic flow at the Interstate 65/KY 480 interchange in Bullitt County. This project will improve access to existing and committed businesses in Cedar Grove Business Park and the surrounding area. 
​Project Scope
Interstate 65/KY 480 interchange
​Type of Project
​Re-Construction as Double Crossover Diamond (DCD) 
The concept of a DCD interchange is to allow the two directions of traffic on the crossroad to temporarily divide and cross to the opposite side to gain access to and from the freeway more easily. A DCD features two-phase traffic signals that typically allow more traffic to flow through the interchange, and fewer conflict points contribute to a reduced number of crashes.

The selected alternative design (DCD) will offer: 
  • A more balanced improvement to the KY 480 signalized intersections on each side of I-65. The two-phased traffic signals provide better coordination with the other traffic signals in the KY 480 corridor

  • Both entrance ramps to I-65 are free-flow ramps. Crossed-over traffic does not have to wait at a traffic signal to enter I-65.

  • Analysis shows that traffic will not back up onto I-65

  • There was a concern with the other alternative: during the construction of its retaining wall under I-65, some of the interstate lanes would have to be closed to remove vehicle loads.

  • It has the greatest potential to serve any future development in the KY 480 area west of I-65.

​Project Timeline

  • As of Summer 2023 (SUBJECT TO CHANGE)

    • The Right of Way phase has been completed.
    • Relocation of LG&E (gas) and Salt River Electric (overhead electric) has been completed.
    • Water (LWC) and sewer (City of Shepherdsville) are set to be located with the road contract.
    • All communications relocations have been completed. 
    • The project is anticipated to be in a Fall 2023 letting. 
Non-selected alternative
Hybrid of the Texas U-Turn interchange. The typical Texas U-Turn interchange design is frequently used on freeways flanked by one-way frontage roads. At freeway interchanges, exiting ramp traffic that desires to access the frontage road on the opposite side of the freeway is routed under the bridge without crossing the opposing traffic on the crossroad - essentially a U-turn movement positioned tight against the bridge abutment. This type of design eliminates several traffic conflict points common with more traditional interchange designs. The normal Texas U-Turn design for the KY 480 interchange is modified to address the heavy southbound to eastbound ramp movement.
​​Public Input
​A public meeting was held on Thursday, June 2, 2016, to present all alternatives and additional information to area residents and motorists. The I-65 Questionnaire submission deadline was June 17, 2016.
