Arcadis | Ooltewah-Ringgold & Standifer Gap Roundabout

Over an 8-year period, the intersection of Ooltewah-Ringgold Road at Standifer Gap Road experienced 45 crashes involving multiple vehicles and serious injuries. The addition of a new middle/high school increased community safety concerns. The challenging offset geometric layout of the intersection made typical fixes such as four-way stops or traffic signals less than optimal alternatives. Hamilton County selected Arcadis to develop the design and provide public outreach and education for Hamilton County’s first roundabout. The roundabout implementation has received continued positive feedback from county government and the community. To date, no fatal or incapacitating crashes have been reported.
