  • The proposed roadway improvements will require crossing Allen Fork.

Existing Conditions

Functional Classification: Major Collector

Existing ADT: 5,900 vehicles per day

2040 Forecasted ADT: 9,700 vehicles per day

Truck Volume: 10%


  • Existing KY 18 (Burlington Pike) is a two-lane facility that connects western Boone County to Burlington, I-71/75 and other arterials in the County.
  • KY 18 is a primary truck route for industries and farms in western Boone County.
  • Expanded residential land use is expected along KY 18 which will increase the traffic volumes along the corridor.

Land Use/Socio-Economic/Environmental:

  • Currently KY 18 serves rural, residential and commercial land uses.  It also is a primary route for trucks from industries in western Boone County.
  • The eastern project limit is located in historic downtown Burlington.
  • By year 2040, population in the project area is expected to grow by approximately 3,500 households.


  • There are existing geometric deficiencies along the route which consist of narrow shoulders, sharp curves and narrow lanes which can be dangerous for trucks, vehicles, and bicycles.
  • The existing crash rate along the roadway is less than the statewide average.  However, there was a fatality along this section of roadway within the five-year period from 2012 through 2016.  This head-on crash occurred in a curve, which suggests that geometric deficiencies consisting of sharp curves, narrow shoulders narrow lanes, and superelevation were a likely contributing factor.


  • On the eastern end of the project limits, there is an 850-foot segment with sidewalks along both sides of KY 18. The existing and proposed sidewalks connect to a network of dedicated pedestrian facilities throughout downtown Burlington and along KY 18.
