PID 117562

This project is to convert the current skewed intersection at Fairground Road and Hilltop Road into a single-lane roundabout to improve safety and sightlines for the travelling public.  

ANNOUNCEMENTS

November 4, 2022 Governor DeWine announces 50 new Traffic Safety Projects

PROJECT LOCATION

The intersection of Fairground Road and Hilltop Road is a 65 degree angle with a 25 degree skew.  

BACKGROUND

There is a 7% grade at the crest of the vertical curve through the intersection.  This combination creates a dangerous area for motorists. This intersection is considered the 6th highest statewide rural intersection for crashes and ranks first in ODOT district # 8. 

  • Crash data between 2017 and 2019:
    • 13 injury crashes = 65.0% (vs. 35.06% statewide average)
    • 17 angle crashes = 85.0% (vs. 29.64% statewide average)
    • 4 left turn crash = 9.52% (vs. 8.95% statewide average)
    • 1 pedestrian crash = 4.76% (vs. 0.27% statewide average)
    • 17 angle type crashes attributed to vehicles on Hilltop Road failing to yield to vehicles on Fairground Road (sight distance limitations).
    • Of the 17 angle crashes, 12 crashes (70-percent) involved westbound vehicles failing to yield to southbound vehicles.

PREVIOUS COUNTERMEASURES

Previous attempts have been made to improve safety conditions at the Fairground Road/ Hilltop Road intersection, including the following mitigation measures:

  • Overhead flashing, warning beacons at the intersection
  • Advanced "stop-sign ahead" warnings on both Hilltop Road approaches
  • Dual stop signs with supplemental "cross traffic does not stop" signs on both Hilltop Road approaches
  • Advanced "intersection ahead" warning signs with flashing beacons on both Fairground Road approaches

SAFETY STUDY

A new traffic signal was not found to be warranted at this intersection.  Instead, a single lane roundabout is the preferred alternative and safest solution.  

See our Roundabouts page for more information about how they work and why they are a preferred solution for problem intersections.

FUNDING

  • The Greene County Engineer secured 90% County Engineers Association of Ohio (CEAO) Highway Safety Improvement Program (HSIP) federal funding in 2021 to perform a safety study of this intersection.
  • In November, 2021, the Greene County Engineer secured $1.4M County Engineers Association of Ohio (CEAO) Highway Safety Improvement Program (HSIP) funding for construction
  • In November, 2022, the Greene County Engineer secured $1.5M in Ohio Department of Transportation (ODOT) Highway Safety Improvement Program (HSIP) funds for engineering, right-of-way, environmental, and construction
  • Estimated total cost (FY 2027) includes engineering, right-of-way, environmental, and construction is $3.5 million

NEXT STEPS

A consultant has been selected for the project and we are currently negotiating the consultant design contract.
