Editing One-way pair (section)

===United States===
[[Interstate 78]] travels along a one-way pair of surface streets, [[New Jersey Route 139#I-78 concurrency|12th Street and 14th Street]], in [[Jersey City, New Jersey]], between the end of the [[New Jersey Turnpike]] Newark Bay Extension and the [[Holland Tunnel]], which leads into [[New York City]], [[New York (state)|New York]].

There are hundreds of one-way pairs among the streets and avenues of New York City. One example is [[Fifth Avenue]] with [[Madison Avenue]]. Others include [[First Avenue (Manhattan)|First Avenue]] with [[Second Avenue (Manhattan)|Second Avenue]]; [[Third Avenue]] with [[Lexington Avenue]]; and [[Seventh Avenue (Manhattan)|Seventh Avenue]] with either [[Sixth Avenue (Manhattan)|Sixth Avenue]] or [[Eighth Avenue (Manhattan)|Eighth Avenue]].

Two major streets in the city of [[Pittsburgh]] serve as a one-way pair; [[Forbes Avenue]] and [[Fifth Avenue (Pittsburgh)|Fifth Avenue]]. Both streets begin in [[Downtown Pittsburgh|Downtown]] near [[Point State Park]] before becoming a one-way pair just east of [[Market Square (Pittsburgh)|Market Square]], with Forbes serving outbound traffic and Fifth serving inbound traffic, going through [[Uptown Pittsburgh|Uptown]] and [[Oakland (Pittsburgh)|Oakland]] before both streets end up with two-way traffic and diverge, with Fifth Avenue eventually terminating in [[Highland Park (Pittsburgh)|Highland Park]], while Forbes terminates in [[Wilkinsburg, Pennsylvania|Wilkinsburg]] just outside the city limits. The mostly two-way [[Boulevard of the Allies]] parallels Forbes and Fifth for most of the time the two streets are a one-way pair.

The east side of [[Portland, Oregon]], features a number of one-way pairs, both north–south and east–west, with the east–west pairs being associated with bridges; these all follow the usual flow convention – see [[Transportation in Portland, Oregon#Traffic flow|Transportation in Portland, Oregon]], for more details. By contrast, the [[Portland Transit Mall]], which is a public transportation (bus and rail) corridor, has the opposite flow, with the westernmost component (6th Avenue) running north, with the eastern component (5th Avenue) running south.

There are a number of one-way pairs in [[Downtown Los Angeles]], [[California]].  These include [[3rd Street, Los Angeles|3rd and 4th Streets]], [[Los Angeles streets, 1-10|5th and 6th Streets, 8th and 9th Streets]], [[Los Angeles streets, 11-40|11th and 12th Streets]], and [[Main Street (Los Angeles)|Main]] and [[Spring Street Financial District|Spring Streets]].<!--no direct article on spring street at December 2015-->

Levick Street and Robbins Street in [[Philadelphia]] are considered a one-way pair. The streets carry traffic to and from the [[Tacony-Palmyra Bridge]] through the [[Mayfair, Philadelphia|Mayfair]] and [[Wissinoming, Philadelphia|Wissinoming]] neighborhoods. Between Frankford Avenue and [[Roosevelt Boulevard (Philadelphia)|Roosevelt Boulevard]], the streets carry [[U.S. Route 13 in Pennsylvania|US 13]] in their respective direction.

In [[Orlando, Florida|Orlando]], [[Florida]], Princeton Street carries 4 miles of SR-438 near [[Interstate 4]]. Over a portion of that, Smith Street carries the westbound traffic. At Lake Lawsona, Mills Avenue splits into Jackson Street northbound and Thornton Avenue southbound.

In Virginia Beach, Virginia, the eastern end of Interstate 264 transitions to 21st and 22nd Street, each going in its respective direction.<ref>{{cite web |url=http://www.roadstothefuture.com/I264_VA_Desc.html |title=Interstate 264 in Virginia |publisher=Roadstothefuture.com |date= |access-date=2022-03-20}}</ref>
