Longest one way road?

[Roadgeekteen]

A random thought that just popped into my head. What is it?

If you don't require it to be one-way all the time, it's probably something in contraflow for hurricane evacuation.

More looking for permanent one way roads, but these could work too.

Also, no nonsense with split carriageways.

Numbered avenues in Manhattan?

Numbered avenues in Manhattan?

1st and 2nd Avenue are one way from Houston St up to 125th St.   5th Avenue is one way from Washington Square (7th St) to 143rd St, with a gap from 120th to 124th St.

[AlexandriaVA]

Yeah, I was checking out first Ave as your typed your own post. About seven miles.

A random thought is just something that pops into your head at an odd moment, but that's not important right now.

Cades Cove Loop Road in the Great Smoky Mountains National Park is 11 miles long, one-way counterclockwise, and one lane wide.  No way could I drive it without first taking a horse tranquilizer, especially during tourist RV season.

I was thinking central park is enormous for where its at, turns out its the 5th biggest park in new York city.  perspective is everything  i.e. those manhattan streets have to be fairly short

This isn't longer than the 1st Ave example in New York, but it is a bit of an interesting case: the one-way couplet that used to be part of US 99 through Centralia, WA continues south of downtown for a total distance of just under 4 miles. https://www.google.com/maps/dir/46.6768134,-122.9641372/46.728876,-122.952267/@46.7074102,-122.9439322,15474m/data=!3m1!1e3!4m2!4m1!3e0?hl=en&authuser=0

Cades Cove is the first thought that popped into my mind. There's another one-way loop near Gatlinburg that's not quite as long as Cades Cove.

2nd St in Duluth is one-way for 3 miles from Mesaba Ave to 24th Avs East.

In the Twin Cities it might be the Portland Ave/Park Ave pair in Minneapolis, about four miles from Washington Ave to 46th St.

Jefferson St in Phoenix is a little over 5 miles long as a one way street. One way begins at 27th Ave and goes east to just east of 24th St, where it does a curve and becomes EB Washington St. WB Washington is one way going WB from east of 24th St to just west of 15th Ave. The road curves from there and becomes Adams St going WB. The one way for Adams St ends at 27th Ave.

Acadia National Park's Loop Road is 13.3 miles long on the one-way portion

Titus Canyon Road in Death Valley National Park is about 27 miles long, the easternmost 24 miles being one-way westbound. While it sounds like my kind of rough, unpaved backcountry road, I've never driven it in multiple visits to the park.

AFAIK, Southside Drive in Yosemite National Park is entirely one-way eastbound, and about 6.1 miles long. It forms a loop with Northside Drive, which is about as long and mostly one-way westbound. However, Northside seems to have a two-way segment between the Yosemite Lodge and the visitor parking areas in Yosemite Village, near its east end.

Not so much fun with a manual transmission; combine a wedding at the little church with a broken-down Buick at one of the tightest portions...

Scenic Loop or Red Rock Canyon west of Las Vegas is one-way 12 miles.

My first thought was the I-5 Express Lanes in Seattle or the Kennedy Express Lanes in Chicago, as I would consider them separate from the freeways they supplement, and they are contraflow roadways.

Or the I-95/395 express lanes in northern Virginia, which SW of the Pentagon are reversible one-way. About 36 miles, and an extension is in progress.
