Editing Interstate 271 (section)

I-271 begins at an [[Interchange (road)|interchange]] with [[Interstate 71 in Ohio|I-71]] in [[Medina Township, Medina County, Ohio|Medina Township]] to [[Interstate 90 in Ohio|I-90]] in [[Willoughby Hills, Ohio|Willoughby Hills]], with an interchange with [[Interstate 480 (Ohio)|I-480]] (and traveling [[concurrency (road)|concurrently]] with it for a short stretch). The width varies from point to point but is mostly four to six lanes wide south of I-480 and eight to twelve lanes wide north of I-480; there, it is divided into [[local–express lanes]].

The local–express lanes begin at the southern interchange of [[U.S. Route 422 in Ohio|U.S. Route&nbsp;422]] (US&nbsp;422) and continue northward slightly beyond the end of I-271. The northbound express lanes allow access to all exits (excluding Chagrin Boulevard, Harvard Road, and [[Ohio State Route 175|State Route&nbsp;175]] (SR&nbsp;175), a southbound-only exit). The southbound express lanes bypass all exits except for one combined exit for Chagrin Boulevard (west US&nbsp;422), Harvard Road, Richmond Road (SR&nbsp;175), and US&nbsp;422 (east) interchange. The lanes then become the mainline of I-480N which in turn becomes I-480 westbound.

I-271 does not have a direct interchange with [[Interstate 80 in Ohio|I-80]]/[[Ohio Turnpike]]—one of only a few examples of Interstate Highways that cross but do not intersect. The I-271/I-480 section was the only instance of a concurrency of two three-digit Interstate Highways in the nation until 2022, when a concurrency between [[Interstate 587 (North Carolina)|I-587]] and [[Interstate 795 (North Carolina)|I-795]], and [[Interstate 840 (North Carolina)|I-840]] and [[Interstate 785|I-785]] in North Carolina was established with the designation of I-587, I-785, and I-840.<ref>{{Cite map |author=((OpenStreetMap contributors)) |date=3 January 2023 |title=United States of America |url=https://www.openstreetmap.org/relation/148838 |website=[[OpenStreetMap]] |access-date=4 January 2023}}</ref>  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.
