Interstate 675

Interstate 675 may refer to:

Interstate 675 (Michigan)

Interstate 675 (I-675) is an auxiliary Interstate Highway in the US state of Michigan. The freeway is a 7.73-mile-long (12.44 km) loop route through downtown Saginaw as I-75 passes on the east side of the city. I-675 is also a state trunkline highway that provided a bypass of the former drawbridge carrying I-75 and US Highway 23 (US 23) across the Saginaw River. Construction of I-675 started in 1969 and the freeway opened in 1971. Since then, sections near downtown were reconstructed in 2009 through 2011 to update one of the freeway's interchanges and rebuild the bridge over the Saginaw River.

Route description

I-675 splits from I-75 on the eastern side of Saginaw, turning west toward downtown. The freeway runs between residential neighborhoods and has an interchange with Veterans Memorial Parkway. West of that interchange, it crosses a line of the Huron and Eastern Railway. From there, it runs on the northern edge of downtown near the Dow Event Center, crossing the Saginaw River on the Henry G. Marsh Bridge. On the west side of the river, the trunkline meets an interchange with M-58. From there it turns northward, crossing a line of the Mid-Michigan Railroad. I-675 continues northward, passing to the east of the Aleda E. Lutz VA Medical Center and through more residential neighborhoods in Saginaw Township North. After the interchange with Tittabawassee Road, which provides access to the Fashion Square Mall, I-675 turns northeasterly to merge back to I-75 north of the Zilwaukee Bridge.

Interstate 675 (Ohio)

Interstate 675 (I-675) is an auxiliary interstate highway in the suburbs of Dayton in the U.S. state of Ohio. Interstate 675 serves as an eastern bypass of Dayton. I-675 measures 26.53 miles (42.70 km) in length. As originally proposed, the route was to reconnect with I-75 north of Dayton near Northridge rather than going east towards 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.

Route description

From the south, the highway begins at Interstate 75 in Miami Township, with four lanes. The highway opens to six lanes just after the interchange with State Route 725 in Washington Township. The next major junction is made with U.S. Route 35 in Beavercreek, which is a full-access interchange. The highway reduces to four lanes just after the interchange with North Fairfield Road. The highway interchanges with Interstate 70 near Fairborn, where it ends. The road continues as two lane Spangler Road, which leads to the unincorporated community of Medway.
