Interstate 271
Auxiliary Interstate Highway in Ohio, United States
Interstate 271 (I-271) is an auxiliary Interstate Highway in the suburbs of Cleveland and Akron in the US state of Ohio. The highway is officially designated the Outerbelt East Freeway but is rarely referred to by that name by locals, instead simply referring to it as "271".
Route description
I-271 begins at an interchange with I-71 in Medina Township to I-90 in Willoughby Hills, with an interchange with I-480 (and traveling 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 (US 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 State Route 175 (SR 175), a southbound-only exit). The southbound express lanes bypass all exits except for one combined exit for Chagrin Boulevard (west US 422), Harvard Road, Richmond Road (SR 175), and US 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 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 I-587 and I-795, and I-840 and I-785 in North Carolina was established with the designation of I-587, I-785, and I-840.

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 23, 2025. The linked authority identifier is Q1131668. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2022.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it.
