The Ohio Department of Transportation constructed the state’s first SmartLane, a nine-mile stretch of I-670 between downtown Columbus and John Glenn Columbus International Airport. The eastbound shoulder has been turned into a lane drivers can use during peak traffic.
The SmartLane features digital signage along the route to announce whether it’s open or closed and to constantly update drivers about road conditions and the variable speed limit. The SmartLane is also outfitted with high-definition cameras so traffic monitors can constantly watch conditions on the road. The cost to develop the SmartLane, which will be used only during peak congestion, is significantly less than the cost of building an additional lane.
