TDOT surveyors were recently spotted at the intersection of Highway 70E and Miller By-pass explaining they were surveying the possibility of a ’roundabout’ intersection there. The surveyors said right now TDOT is just contemplating a change of the four-way intersection and nothing is in the works for anytime soon. And just in case you’re wondering what a ’roundabout is…”a circular area where three or more roads meet that you have to drive around in one direction in order to get onto another road. The American word is traffic circle or rotary.
Widespread use of the modern roundabout began when the UK’s Transport Research Laboratory engineers re-engineered and standardized circular intersections during the 1960s
