County Roads 8 & 41 Roundabout

In 2013, the Ontario County Department of Public Works completed a network screening of the County’s unsignalized, two-way stop-controlled intersections using data ranging from January 2008 to December 2010. Results indicated that the County Road 8 and County Road 41/Shortsville Road intersection experienced the largest number of crashes with a rate well beyond the expected crash frequency for similar intersections. It ranked as the County’s worst performing two-way stop controlled intersection. Whether stopped motorists are misjudging the relatively high speed of approaching traffic or the length of available gaps, the end result is often a series injury crash.

Six possible alternatives were reviewed, with a modern roundabout being chosen as the plan to improve safety at this intersection. The roundabout would physically eliminate left turns and crossing maneuvers, therefore mitigating documented accident patterns. A reduction in intersection approach speeds would also reduce the severity of any collisions that continue to occur. Elements of the project are as follows:

     • Roundabout will feature an 18 ft wide circulatory roadway with an inscribed circle diameter of 130 ft
     • It will have a truck apron and a landscaped central island
     • Each approach will feature an elongated splitter island with a set of curves,
               each successively smaller as one approaches the circle, to reduce vehicle speeds as 
               they approach the roundabout
     • Drainage improvements will be included to facilitate flow around the intersection

The County sought and secured Highway Safety Improvement Program (HSIP) funding for this project. Construction began in June of 2015 with a road closure; it is expected that the intersection will be re-opened to traffic after Labor Day.  The project is expected to be completed by October of 2015.
