In spring 2016, in response to the Franklin County Board of Supervisors submitting a SMART SCALE application, the Commonwealth Transportation Board included funding in the Six-Year Improvement Program for a project to improve safety at the intersection of Route 122 and Hardy Road in Franklin County.

As the funds became available, VDOT developed a project to construct a new left turn lane on northbound Route 122. This project was intended to reduce rear-end collisions, the predominant crash type at the intersection in previous years.

In fall 2019, in light of recent crashes, VDOT re-evaluated the intersection and determined that the predominant crash type had changed with rear-end collisions decreasing and the angle crashes increasing and left-turn crashes from Hardy Road onto Route 122 almost doubling.

As a result, VDOT is pursuing changing the scope of the project and refining the design to provide improvements that enhance safety given the more recent crash pattern. VDOT considered a traffic signal and a roundabout for the improvements.

Compared to signalized intersections, roundabouts offer enhanced safety benefits, improved efficiency, reduction in speeds and lower long-term maintenance costs. Therefore, VDOT is moving forward with plans for a roundabout.

Why a Roundabout?

  • Improved Safety: Reduces the number of points where vehicles can cross paths and minimizes the potential for right-angle and head-on crashes because all movements are right turns.
  • Increased Efficiency: Yield-controlled design means fewer stops, less delay and shorter queues for overall improved efficiency as compared to a traffic signal.
  • Safer Speeds: Promotes lower vehicle speeds, giving drivers more time to react.
  • Long-Term Cost Savings: No traffic signal equipment means lower long-term costs for operations and maintenance.
