The I-670 corridor in Columbus, Ohio, serves as the major artery connecting downtown to the John Glenn International Airport. Burgess & Niple (B&N) led an eight-consultant team to design an Active Traffic Management Strategy called Hard Shoulder Running (HSR) to combat congestion on this crucial roadway. HSR is the temporary use of the shoulder to provide an additional lane of capacity during peak travel hours.
This approach is significantly less expensive than other options, such as traditional road widening, because it uses the existing roadway infrastructure and typically requires fewer impacts to overhead bridges, interchange ramps and signs. The versatile solution also provides the Ohio Department of Transportation (ODOT) with a dynamic system that will allow them to respond to various traffic challenges as they arise.
