(SR 122A) is downhill at a grade (4-5%). It includes multiple crosswalks at all legs and even one mid-roundabout.

Worthington Rd/ Lewis Center Rd; Delaware County, OH – This is a 4-leg peanut roundabout under design at a Highway Safety Improvement Program (HSIP) location.

County Line Rd/ Center Village Rd/Edwards Rd/ Duncan Plains Rd NW; Delaware County, OH – This is a 5-leg peanut roundabout to be designed having a US Bike Route (USBR 50A) and high-speed approaches (55 MPH).

• How do the Far Hills Ave and Oakwood Ave grades impact the roundabout? A primary benefit of roundabouts is that they reduce vehicle speeds. The geometry of roundabouts requires vehicles to slow down as they approach and traverse the intersection. Vehicles traveling northbound (downhill) and southbound (uphill) on Far Hills Ave will be braking as they approach the roundabout, as opposed to maintaining normal speed or perhaps even accelerating as they approach the intersection. The existing 85^th percentile speed north of Five Points is 45 MPH despite the posted speed of 35 MPH. The grades will not adversely impact the functionality of the roundabout.
• How does the cost of a roundabout compare to a traditional traffic signal? The cost to convert the existing signalized intersection to a roundabout will be significantly higher than the cost to simply replace the existing traffic signal installation. However, lifecycle costs to maintain the roundabout would be lower than lifecycle costs to maintain a traffic signal. Also, it may be that a majority of the cost to build the roundabout would be paid by state and/or federal transportation dollars, effectively making the local share (Oakwood taxpayer expense) comparable to, or perhaps even less than, the cost of rebuilding and upgrading the traffic signal.
