Interstate 675 Ohio
Connecting I-75 in Miami Township with I-70 in Mad River Township, Interstate 675 forms an eastern bypass of Dayton to the south and east, providing part of a regional route south to Cincinnati and east to Springfield. The freeway loop also travels through the cities of Centerville, Kettering, Beavercreek and Fairborn and serves Wright-Patterson Air Force Base.
The original proposed alignment for Interstate 675 called for it to loop back to I-75 in the vicinity of Northridge. It was later realigned to link with I-70 west of Springfield.
Interstate 675 was approved by the American Association of State Highway and Transportation Officials (AASHTO) on June 23, 1969. The freeway was completed by 1989.
