Graves Road Interchange
Project Information
Facility: I-275
Location: Graves Road
Project Type: Roadway Widening/Relocation/New Facility
Priority Level: Tier 1
Project Description:
- Construct a new interchange on I-275 at Graves Road to improve mobility and reduce congestion in the Hebron area as recommended in the Kentucky Transportation Cabinet’s Graves Road Interchange Justification Study.
- Include improvements to Graves Road from KY 237 (North Bend Road) to KY 20 (Petersburg Road).
- Install a multi-use path on Graves Road to accommodate bicycles and pedestrians.
Cost Estimate:
| Design | Utilities | Right of Way | Construction | TOTAL |
| $4,000,000 | $2,000,000 | $12,710,000 | $23,700,000 | $42,410,000 |
Benefits:
- A new interchange on I-275 at Graves Road will provide alternate access to I-275 for residents, businesses and trucks in the Hebron area, thereby alleviating travel demand and congestion on KY 237.
- Safety will be improved by correcting geometric deficiencies on Graves Road.
- Added roadway capacity provided by Graves Road will accommodate future increases in traffic volumes expected from the interchange construction and future development in the Hebron area.
- Improvements to Graves Road and additional access to I-275 will enhance access to a TANK Park & Ride lot and provide new, potentially more efficient transit routing options.
- The Graves Road multi-use path will connect to the existing KY 237 path, the proposed KY 20 (Petersburg Road) path from Graves Road to KY 237, and the surrounding Boone County bicycle/pedestrian network. This recommendation is consistent with Boone County’s overall goal of improved bicycle and pedestrian connectivity and safety. Click HERE for a map of multi-use paths in Boone County.
Challenges:
- Potential historic sites on the National Register of Historic Places are located in the project area.
- The Graves Road interchange and improvements will require additional right-of-way.
Existing Conditions
Functional Classification:
- I-275 – Interstate
- Graves Road – Major Collector
2040 Forecasted ADT:
- I-275 – 45,600 vehicles per day
- Graves Road – 10,100 vehicles per day
Existing ADT:
- I-275 – 33,470 vehicles per day
- Graves Road – 2,320 vehicles per day
Truck Volume:
- I-275 – 16%
- Graves Road – Not Available
Congestion:
- KY 237 (North Bend Road) in Hebron is heavily congested. OKI’s Travel Time Index tool states that vehicles traveling on KY 237 experience a travel time delay of almost 50 percent.
- Additional traffic volumes are expected in the Hebron area as industrial, commercial, and residential development continues in the area.
- To avoid congestion at the I-275 interchange, many residents in the Thornwilde and Treetops subdivisions currently use Graves Road as an alternative route.
Land Use/Socio-Economic/Environmental:
- Future 2040 land use maps show the residential and industrial expansion in the Hebron area.
- There are potential historic sites on the National Register of Historic Places and a fire station identified within the project area.
- TANK route 40x serves industrial developments in the Hebron area along World Wide Boulevard, South Park Drive, Global Way, and KY 237. There is also a TANK Park & Ride lot located at the Cardinal Way/KY 237 roundabout.
Safety:
- The frequency of crashes along Graves Road is 80 percent higher than the statewide average for similar roadways. With no additional improvements, there is a high potential in the future for an increase in crashes as more vehicles use Graves Road.
Multi-Modal:
- There are no dedicated bicycle or pedestrian facilities along Graves Road. OKI’s Bike Route Guide classifies this route as a “preferred route.”
- There is an existing multi-use path on KY 237 that connects residential, commercial, and industrial developments.
