ODOT breaks ground on new interchange in Delaware County
Improved Interchange at I-71/U.S. 36/SR 37 and Proposed Sunbury Parkway

DELAWARE – The Ohio Department of Transportation (ODOT) District 6 officially broke ground on a $32 million project to construct a new combined interchange on Interstate 71 in Delaware County. Located about one mile south of the existing U.S. 36/SR 37 interchange, the new interchange will work in conjunction with the current ramps to improve traffic flow throughout the area.
This new interchange is the first phase for construction of Sunbury Parkway, a new 4.3-mile east-west roadway that will extend from Africa Road at U.S. 36/SR 37 to West Cherry Street in the City of Sunbury. Wilson Road will also be extended south to connect with the future Sunbury Parkway.
Once complete, the interchange and its supporting roadway network will improve connectivity for local and freight traffic, relieve congestion, and enhance safety at the existing I-71 and U.S. 36/SR 37 interchange.
“This project is a perfect example of what can be accomplished when public and private sector partners work together toward a shared goal,” said Toni Turowski, ODOT District 6 Deputy Director. “By improving access and mobility in one of Ohio’s fastest-growing counties, we’re not just easing congestion -- we’re laying the groundwork for continued economic growth and safer, more connected communities.”
The project will be built in six phases based on anticipated traffic demands. Construction is expected to span from 2025 to 2035, with a total estimated cost of $189 million for all phases.
The first phase, which officially began today, will construct a partial interchange to address the most immediate traffic needs. Work is expected to continue through 2027, with most major traffic impacts scheduled during off-peak hours to reduce disruptions for drivers.
This significant investment supports Delaware County’s ongoing population growth and economic development. The new infrastructure will enhance east-west mobility, support the efficient movement of goods, and improve access to future job centers, housing, and retail development.
