Interstate 380

Interstate 380 may refer to:

Ohio State Route 8

State Route 8 (SR 8) is a road in the U.S. state of Ohio. SR 8 stretches from the eastern junction of I-76 and I-77 in Akron to Public Square in Cleveland. It is one of 9 other routes to enter downtown Cleveland at Public Square. The route's first few miles are as a limited-access freeway from I-76 and I-77, heading north. The freeway section of the highway has 16 interchanges, and is cosigned with SR 59 for a short distance from Perkins Street in Akron to Front Street in Cuyahoga Falls. The freeway portion ends at I-271 in Macedonia.

Route description

SR 8 begins at an interchange with I-76 and I-77 just southeast of Akron's central business district. The Akron Expressway, as the freeway is known within the city limits, heads up the east side of Akron. SR 8's first interchange is the main access to the central business district and the University of Akron. Just before leaving the center of Akron, an interchange with Perkins Street begins a concurrency with SR 59. The road continues over the North Expressway Viaduct, which crosses over several railroads and the Little Cuyahoga River, before continuing to the north side of Akron. Between exits 3B and 4, SR 8/59 cross into Cuyahoga Falls. Those two exits connect with the same stretch of road, but they have different names and are on different sides of the city limit.

Interstate 380 (Iowa)

Interstate 380 (I-380) is a 73-mile (117 km) auxiliary Interstate Highway located in eastern Iowa. The route extends from Interstate 80 near Coralville to Waterloo. I-380 connects the cities of Cedar Rapids and Waterloo, the second- and sixth-largest cities in the state, respectively, to the Interstate Highway System. Except for its last 1 ¹⁄₂ miles (2.4 km) north of U.S. Route 20 (US 20), I-380 runs concurrent with Iowa Highway 27, which represents Iowa's portion of the 560-mile (900 km) Avenue of the Saints Highway connecting St. Louis, Missouri, with St. Paul, Minnesota.

Construction of I-380 took 12 years to complete, ending in 1985. After the interstate opened, US 218 was moved onto the new freeway. In the 1990s, the I-380 corridor was selected as part of the Avenue of the Saints corridor, which Iowa designated as Iowa Highway 27 in 2001. I-380 has been affected by two major floods, the Great Flood of 1993 and the Iowa flood of 2008, both of which closed the road at the Iowa River for two weeks.
