Richwood Rd. Interchange Improvements 


is the scope of the project?

The Richwood Rd. Interchange Improvements project:


  • Replaced the existing interchange at Richwood Rd. (KY 338) and I-71/75 with a double crossover diamond (DCD) interchange. This innovative solution has been proven to result in significant reductions to both crashes and delays by eliminating left turns made against oncoming traffic.

  • Replaced the current intersection at Richwood Rd. and Dixie Highway (US 25) with a newer and safer traffic pattern, known as a single point urban interchange (SPUI). This allows for freer movement of traffic along Richwood Rd., which passes under Dixie Highway. Dixie Highway traffic will move continuously via a bridge over Richwood Rd.

  • Constructed a roundabout at the intersection of Richwood Rd. and Triple Crown Blvd.

  • Eliminated two railroad crossings by constructing an overpass railroad bridge. Richwood Rd. now goes under the bridge.

  • Widened Richwood Rd. from Triple Crown Blvd. to Old Lexington Pike and widened Dixie Highway from Logistics Blvd. to the north of Winning Colors Dr. Road widening allows for the addition of dedicated turn lanes at the interstate and Richwood Rd./Dixie Highway interchanges.

  • Added a multi-use path and sidewalks, as well as a raised median along Richwood Rd.

  • Improved access to area businesses. 


are these improvements taking place?

The Richwood Rd. Interchange Improvements will dramatically improve safety, reduce travel time delays and provide better connections to a growing number of businesses in the area. Additionally, they will greatly increase access to three truck stops along this important segment of the National Highway Freight Network.


Significant regional growth and increasing traffic volumes have also led to higher crash rates than the statewide average for similar roadways. Double crossover diamond (DCD) interchanges dramatically improve safety because they eliminate numerous traffic conflict points. DCDs also move drivers through high traffic areas much more efficiently.


The single point urban interchange (SPUI) – pronounced “Spooey” – is increasing in popularity for many of the same reasons, and because this type of interchange pattern separates traffic moving to and from the interstate from through traffic.


Roundabouts help keep traffic moving at safer speeds and have been proven to be safer than traditional intersections with traffic signals.


New shared-use paths improve access for bicyclists and pedestrians while connecting to a planned multi-use trail throughout the region.


The elimination of the two railroad crossings and construction of the overpass railroad bridge vastly improve safety and congestion and provide unlimited access to and from the industrial park and the Walton Fire Station.


will work begin and end?

This project was completed in Fall 2023. Corrective work within the project limits is expected to take place through Summer 2023.


will there be impacts to traffic because of the project work?

Corrective work is in progress within the project limits. This work may require minor traffic impacts.

much will the project cost?

The construction cost is expected to be approximately $60 million.
