in 1975 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. 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. ==History==
