Interstate 275 (I-275) is an 83.71-mile-long (134.72 km)[1] highway inOhio,Indiana, andKentucky that forms a completebeltway around theCincinnati metropolitan area and includes a part in a state (Indiana) not entered bythe parent route. It had been the onlyauxiliary Interstate that enters three states, but that changed in July 2018 whenI-295 in Delaware and New Jersey was extended into Pennsylvania. It is the longest beltway with an Interstate highway designation in the United States,[2] enclosing an area of over 250,000 acres (100,000 ha).[3] It is also the third longest beltway overall in the United States; only theSam Houston Tollway and theGrand Parkway, both encirclingGreater Houston, are longer. For a short distance in northwestHamilton County, itoverlaps withI-74 andUS Route 52 (US 52). It is also concurrent with US 52 very briefly in southern Hamilton County as well.
I-275 is also known as theCincinnati Bypass and officially known as theDonald H. Rolf Circle Freeway in Ohio, after a state senator,[4] but locals rarely use these names, instead simply referring to it as "275" or "the loop". In 2011, Kentucky named its segment theRonald Reagan Highway, not to be confused withRonald Reagan Cross County Highway across the river in Cincinnati.[5] The section inClermont County is also designated as theStaff Sergeant Matt Maupin Veterans Memorial Highway.

I-275 turns east, having an interchange withSR 4,SR 747,I-75, andUS 42. I-275 turns southeast, having an interchange withI-71 andUS 22/SR 3. I-275 passes over theLittle Miami River, enteringClermont County, where it is officially named in honor ofKeith Matthew Maupin, a local soldier killed during theIraq War. I-275 turns due south towardMilford and connects withSR 28,SR 450,SR 32, andSR 125.

On May 20, 2008, a tractor-trailer hauling a locomotive separated while traveling on the ramp from westboundI-74 to southbound I-275. After the trailer detached, it crashed into supports for the bridge on I-74 eastbound going over the ramps between I-275 and I-74 westbound. As a result, theOhio Department of Transportation (ODOT) shut down eastbound I-74 for several weeks.[6] Both ramps between I-74 west and I-275 were closed as well because of fears the bridge would collapse, but two crossovers were built so that traffic could use one lane of westbound I-74 to travel east around the damaged bridge.[7]
