Highways that can only be driven in one travel direction

[Max Rockatansky]

While I was recently on Maui I did a quick drive on unsigned Hawaii Route 3600 which is an interim 0.4 mile state route on Paia Mini-Bypass.  Hawaii Route 3600 is a single lane highway which can only be driven eastbound only.  What other state or DOT maintained highways are out there that only be traveled solely in one direction?

I-878 in New York, perhaps? I think that unposted route number only applies eastbound.

There's a 0.7 mile reversible section of FL 618 near Brandon which isn't accessible at all times of day. Such is life that I can never seem to be going in that clinchable direction at the right time...having clinched it decades earlier is kind of irritating.

Probably a few more like this in the age of express and toll lanes.

Head 200 miles northwest to Kapaa on Kauai and the first 3/4 mile of HI 5600, the Kapaa bypass, is one-way southbound only. I rarely use the bypass northbound because when you get to the one-way segment, it then dumps you into downtown Kapaa plus you've had the expense of a couple of difficult left turns.

The Woodward Avenue loop (BL I-75 and BL US-24) in Pontiac MI can be driven only in a counterclockwise direction.  There is a short wrong-way concurrency at the top of the loop (south BL 75 and north BL 24) that doesn't exist in the opposite directions.

(This will change in a couple years when MDOT rebuilds it as a two-way boulevard.)

Washington SR-41. It straddles the Idaho state line at Newport, WA/ Oldtown, ID. WA-41 is southbound only for a few blocks until the highway turns into Idaho fully. For simplicity, it is signed as ID-41 only.

US-219 Truck in Ridgway, PA. 2 of the 3 segments are one-way NB only. The middle segment is concurrent with PA-120.

I-878 in New York, perhaps? I think that unposted route number only applies eastbound.

I am 99% sure that is correct.

[froggie]

ALT US 60 in Norfolk, VA only exists in the westbound direction.

[dlsterner]

In Cresaptown MD (near Cumberland) there is a section of MD 53 of a few blocks (between US 220 and MD 636) that can only be driven southbound.

Took a bit of ingenuity to complete that clinch along with the other roads I was trying to get.

Also in Virginia: 

all of VA 349, VA 393 and VA 399

parts of VA 131 and VA 376

The freeway part of NY 878 by JFK airport (Nassau Expressway) in NYC.

The southern part of MD 528 in Ocean City, MD.

PA 72 in Lancaster has a part where only NB exists.

Then the PA 23 and 462 concurrency is only WB only while EB has the two routes independent of one another.

Unposted ALT WV 3 in Whitesville can only be driven northbound (actual direction)/westbound (posted direction of WV 3).

There are probably a few other ALT and SPUR routes labeled on West Virginia maps that would qualify. I think there may be some shorter routes/streets like this in downtown Welch.

[pderocco]

Not highways, but Black Bear Road going over the pass and down into Telluride, CO is one-way. So is Titus Canyon Rd in Death Valley. Both require going quite far out of the way to go the other direction.

There's a one-way scenic loop near Gatlinburg that I've driven a couple of times.

Cades Cove? If so, I don't think it's numbered, but it is loggable in TM.

Might be thinking of the Roaring Fork Trail.  It's a 10-ish mile one-way loop beginning and ending in Gatlinburg.  10 mph speed limit IIRC.  Drove it once about a decade ago.

Yep, that's it. Name was on the tip of my tongue fingers.

MDOT is planning to make that section of MD 53 two-way by building a new northbound lane: https://mdot-sha-us220-intrs-at-md53-al445111-maryland.hub.arcgis.com/

Also in Virginia: 

all of VA 349, VA 393 and VA 399

parts of VA 131 and VA 376

There's also the route through Petersburg National Battlefield, which IIRC is a 90xxx route.

It is, VA 90230.

Cades Cove was mostly one-way last I drove on it in mid-2020.

(Not really a highway in the traditional sense, but it's in Travel Mapping.)

Would you consider the one-way loop for Drillfield Drive at Virginia Tech (a major section of VA-314) to be "only driven in one travel direction"?  Traditionally, the Drillfield was entirely a one-way loop around the Drillfield, a 22-acre oval park that is at the heart of campus.  Nowadays, Stanger Street and Kent Street have been interconnected behind War Memorial Chapel (ergo, in front of The Pylons) with a dumbbell arrangement that converts the intersection with The Mall (now Alumni Mall) as a two-way street (hence, Drillfield Drive is no longer a one-way loop all the way around). Back when I was there, most of the traffic on Drillfield Drive went around the entire loop in search of convenient parking. 

I almost learned my lesson as a pedestrian the hard way.  I got complacent at the Drillfield and would only look towards oncoming traffic before crossing.  I once crossed in the path of someone backing up in front of War Memorial Gym after spying a parking space behind him.  He missed me by about 2 inches.  Now I know why I should "look both ways", no matter the traffic pattern.

For the record, Drillfield Drive [can] be used as a one-way pair extension of The Mall between Main Street and West Campus Drive.

It's still VA 314, so it counted for the purposes of this thread before those streets were reconfigured.

One is the central loop motorway in Charleroi, Belgium.  Also, there is a similar central loop somewhere in Japan.
