Mt. Zion Rd. Interchange Improvements


is the scope of the project?

The Mt. Zion Rd. (KY 536) Interchange Improvements project:


  • Replaced the existing interchange at Mt. Zion Rd. (KY 536) 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.

  • Widened Mt. Zion Rd. from three lanes to up to nine lanes from west of the interchange to Dixie Highway (US 25) on the east side. Widening allowed for the addition of new through/turn lanes and a raised median on Mt. Zion Rd. Additionally, new upgraded service roads that provide better access to local businesses weree built.

  • Constructed a shared-use path along the north side of Mt. Zion Rd.

  • Added sidewalks along the south side of Mt. Zion Rd. east of the interchange. Sidewalks were extended in other locations within the project area.


are these improvements

taking place?

The Mt. Zion Rd. Interchange Improvements will dramatically improve safety, reduce travel time delays and provide better connections to a growing number of businesses in the area.


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.


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