Interstate 675 (I-675) is an auxiliary Interstate Highway in the suburbs of Dayton in the US state of Ohio. I-675 serves as an eastern bypass of Dayton that is 26.53 miles (42.70 km) long. As originally proposed, the route was to reconnect with I-75 north of Dayton near Northridge rather than going east toward Springfield and I-70 (this was later rejected because part of the right-of-way would have gone through Wright-Patterson Air Force Base). Construction was completed in 1987, though some have lobbied to extend the highway west of Dayton.
