US 421/KY 676 – Leestown Road

Franklin County, Kentucky

This project involved Phase I and Phase II Design for a 3.4 mile section of US 421 in the eastern fringe of Frankfort and Franklin County. It was developed from a Phase I Design project encompassing a more extensive project that included preparation and approval of an environmental document and the selection of an improvement strategy more or less within the existing road corridor and with attention to existing scattered developments. The project was significantly revised after right of way and utility relocations were complete to change the roadway from rural to urban and incorporate a shared use path for much of the length.

A new county elementary school was constructed on the north side; and before construction was complete, three schools were located in this area. This redevelopment quickly supported the critical decision to change from a rural roadway to an urban roadway, but more important, to provide a safer road environment for the expected and now added new developments.
Access management was a significant issue throughout the project. Transitioning from the full control of access to partial control of access to permit access was especially challenging due to Good Shepherd Church on the north side and Storage Facilities/Glenn Toyota dealership on the south side. A raised median was included through this section, and a median transition developed from concrete barrier wall to median curbs with grass to a flush median. A frontage road was included along the south side and right in-right out access for the church on the north side. Work planned on the interchange was reviewed through a “Practical Solutions” approach and approximately $1.0 million of reconstruction deferred for future attention. This decision was based on a review of current traffic volumes and operational issues within the existing interchange.

As construction neared completion, the Legislature included funding for an additional change within the interchange to expand the left turn from US 60 SB to US 421 EB to a dual left-turn lane and widen the ramp to two lanes for this expanded movement. We worked directly with the Resident Engineer while maintaining contact with the District 5 Design Office to expedite work and revise construction plans.
