Interstate 275 (Ohio–Indiana–Kentucky)
auxiliary Interstate highway encircling Cincinnati in the U.S. states of Ohio, Indiana, and Kentucky
Interstate 275 (I-275) is an 83.71-mile-long (134.72 km) highway in Ohio, Indiana, and Kentucky that forms a complete beltway around the Cincinnati metropolitan area and includes a part in a state (Indiana) not entered by the parent route. It had been the only auxiliary Interstate that enters three states, but that changed in July 2018 when I-295 in Delaware and New Jersey was extended into Pennsylvania. It is the longest beltway with an Interstate highway designation in the United States, enclosing an area of over 250,000 acres (100,000 ha). It is also the third longest beltway overall in the United States; only the Sam Houston Tollway and the Grand Parkway, both encircling Greater Houston, are longer. For a short distance in northwest Hamilton County, it runs concurrently with I-74 and US Route 52 (US 52). It also runs concurrently with US 52 very briefly in southern Hamilton County.
I-275 is also known as the Cincinnati Bypass and officially known as the Donald H. Rolf Circle Freeway in Ohio, after a state senator, but locals rarely use these names, instead simply referring to it as "275" or "the loop". In 2011, Kentucky named its segment the Ronald Reagan Highway, not to be confused with Ronald Reagan Cross County Highway across the river in Cincinnati. The section in Clermont County is also designated as the Staff Sergeant Matt Maupin Veterans Memorial Highway.

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Apr 12, 2026. The linked authority identifier is Q788759. 3 of 3 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank. The first chronological checks are 2018 and 2011.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
