Interstate 480 (I-480) is a 41.77-mile-long (67.22 km)auxiliary Interstate Highway ofI-80 in theUS state ofOhio that passes through much of theGreater Cleveland area, including the southern parts of the city ofCleveland. I-480 is one of 13 auxiliary Interstate Highways in the state. The western terminus of I-480 is an interchange with I-80 and theOhio Turnpike inNorth Ridgeville. Starting east through suburbanLorain County, I-480 entersCuyahoga County, then approachesCleveland Hopkins International Airport, which serves as the primary airport forNortheast Ohio. After traversingBrooklyn and crossing theCuyahoga River on theValley View Bridge, the highway continues east toward the communities ofBedford andTwinsburg toward its eastern terminus at I-80 and the Ohio Turnpike inStreetsboro. On its route, I-480 crossesI-71 andI-77 and is concurrent withI-271 for approximately four miles (6.4 km). In 1998, the governor of Ohio,George Voinovich, gave I-480 the additional name of the "Senator John Glenn Highway", in honor of theformer NASA astronaut and US senator from Ohio for 24 years.^[1]

Parts of I-480 were to have beenI-271 and/orI-80N.^[3]

The freeway runsconcurrently withI-271 for two miles (3.2 km). I-271 and I-480 were the only two auxiliary Interstates in the nation that ran concurrently with each other for any distance until 2022, when concurrencies betweenI-587 andI-795 andI-785 andI-840 in North Carolina were established with the designation of I-587^[4] and the completion of the Greensboro Urban Loop.^[5] This is because I-80 was concurrent with I-271 until 1971, when I-80 was routed back on to the turnpike and replaced by I-480.

Due to the convergence of these high traffic roads, congestion is common during peak times. They run concurrently throughBedford Heights,Bedford, andOakwood inCuyahoga County. Because of that, theOhio Department of Transportation (ODOT) started a $120-million (equivalent to $153 million in 2024^[6]) widening project in 2016, separating I-271 traffic from I-480 traffic.^[7][8] The project was completed in 2020.^{[citation needed]}

TheValley View Bridge, which is 212 feet (65 m) high and spans 4,150 feet (1,260 m),^{[citation needed]} carries I-480 across theCuyahoga River valley. It is the busiest crossing in the state of Ohio with approximately 180,000 cars per day.^{[citation needed]}

I-480 was conceived as a means of giving motorists a faster way of crossing Cleveland's southern borders and suburbs.^[9][10] The first segment of the route was partially concurrent withI-271 and constructed simultaneously with that highway in 1965.^[11] Planning for the route was largely finished by 1968, and construction began on its first mile (1.6 km) began at the highway's interchange withI-77 in 1970.^[10]

The segment fromBedford west toMaple Heights opened in November 1976.^[12] The segment from Maple Heights west toBrooklyn Heights opened in January 1978.^[13]

Construction from west to east began as political controversies and engineering work were resolved on the highway's middle section. I-480 betweenI-80 and I-71 was completed in 1983.^[14]

The two miles (3.2 km) of the route north and northeast ofCleveland Hopkins International Airport proved the most difficult to plan due to existing high levels of traffic on Brookpark Road and the expansion requirements of the airport.^[10]

The final $115-million (equivalent to $303 million in 2024^[6]),^[15] 2.5-mile (4.0 km) segment linking the east and west ends of I-480 was finished in August 1987.^[16]
