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.
