Improved Interchange at I-71 and Routes 36/37 and Proposed Sunbury Parkway
The existing diamond interchange at I-71 and US 36/SR 37 was constructed over 40 years ago and is the only interstate access in the central and northern part of Delaware County. Over 30,000 vehicles use the interchange each day to enter or exit I-71. Queuing on the exit ramps at the interchange routinely extends onto the freeway mainline, causing operational and safety concerns. Stopped traffic on I-71 northbound during the afternoon peak hour is a near-daily occurrence as traffic waits to exit onto US 36/SR 37. Unfortunately, the resulting increase in traffic is crippling the potential for future growth. The safety project constructed in 2012 was intended to improve safety and reduce congestion at the interchange in the short term.
