- Reconstruction of KY 237 (Gunpowder Road) will eliminate the geometric deficiencies along the roadway and improve safety.
- Improvements to this portion of KY 237 will complete a series of continuous improvements to the route from KY 536 to Hebron.
- This project will improve mobility by providing a safe and reliable alternative to US 42 and KY 536 (Mount Zion Road).
- The project will reduce the frequency of flooding along the roadway.
- A multi-use trail would provide a continuous connection to commercial development, schools and parks with a scenic view of Gunpowder Creek. This project is consistent with Boone County’s overall goal of improved safety and connectivity for bicycles and pedestrians. Click HERE for a map of multi-use paths in Boone County.
- The project will require additional right of way.

- KY 237 serves as a primary north-south route through central Boone County.
- As housing development in the Union area continues to expand, traffic is expected to increase along this roadway.
- The land use adjacent to KY 237 is primarily rural density housing and churches. The 2040 land use map shows that future suburban density housing is expected in this area.
- Gunpowder Creek runs along the west side of the roadway.
- Potential historic sites on the National Register of Historic Properties were identified within the project area.
- The crash rate along this portion of roadway is over three times the statewide average for similar roadways.
- There are existing geometric deficiencies along the route such as sharp curves, narrow lanes, and narrow shoulders. The existing cross section is not consistent with the use of the roadway.
- The roadway is listed in OKI’s Bicycle Route Guide as “not recommended.”
- Future expansion of suburban density will increase resident demand for dedicated bicycle and pedestrian facilities along the roadway.
- Both the north and south project limits connect to multi-use paths.
