This project is to convert the intersection at Trebein Road, Dayton-Xenia Road, and Hilltop Road into a single lane roundabout to improve safety for the travelling public.
November 4, 2022 Governor DeWine announces 50 new Traffic Safety Projects
The intersection of Trebein Rd, Dayton-Xenia Rd., and Hilltop Rd. is a busy thoroughfare linking /US-35 to the City of Fairborn, SR-235, and I-675, that lies within Beavercreek Township approximately one mile north of the proposed Trebein Rd./ Valley Rd./ US 35 Interchange.
This dangerous intersection in a rapidly growing corridor is the greatest "local" safety concern of the travelling public and law enforcement.
- 19 crashes between 2017 and 2019:
- 10 injury crashes = 52.6% (vs. 35.06% statewide average)
- 14 angle crashes = 73.7% (vs. 29.64% statewide average)
- 4 rear end crashes = 21.0%
- 1 right turn crash = 4.8%
- 57 percent of the angle collisions resulting in injury. All angle collisions were the result of eastbound and westbound vehicles failing to yield to vehicles on Trebein Road.
- Most frequent crash pattern was angle crashes resulting from eastbound drivers on Dayton-Xenia Rd. (West) failing to yield to vehicles traveling northbound on Trebein Road.
- Of the 15 angle and right-turn collisions, 11 involved a northbound vehicle on Trebein Road.
- Slight vertical curve along the south leg of the intersection slightly obstructs northbound vehicles approaching Dayton-Xenia Road (West) and Hilltop Road.
Crash History 2017-2019
A single lane roundabout on a multi-lane footprint is the preferred alternative for this intersection. This roundabout will be easily converted to a multilane in the future as increased traffic volume warrants.
See our Roundabouts page for more information about how they work and why they are a preferred solution for problem intersections.
