Jersey Freeway, Michigan Left, Arkansas Freeway, etc.

An Arkansas freeway is the 5 lane undivided highway like those that exist all over the state.

Sow what does it have in common with an actual freeway?  Multi-lane, yes.  Low-curvature / high-speed alignment, maybe?  Access control, I'm guessing not, or the center turn lane would be fairly pointless...

Could someone direct me to an example of the "Texas Twist". I tried a Google Search, and only got images of guardrails ending in an embankment or the "new" flat ended treatment.


I always joke about the "Michigan Expressway", which is the term I use to indicate a roadway that exclusively uses Michigan Lefts.

Warning, they're nearly 3MB each. Don't have time to make small versions.

There may be one or two intermediate angled posts missing from that example.

The Texas Twist works OK on a low-speed road, but not for roads where you can drive a constant 55 mph or faster.

"Buried in the back slope" is an acceptable replacement for a Texas Twist end treatment if you're doing low-cost safety improvements.

I'd never heard the term Arkansas freeway but much of US 23 in eastern Kentucky would qualify. It's an Appalachian corridor but when the section between Prestonsburg and Paintsville was built in the 1990s, it was touted as a federal "demonstration project." I didn't understand what was being demonstrated, as five-lane highways with a center turn lane were already in common use at the time.

Looks like a four-lane divided highway with a flush median. The Goog doesn't show any center turn lane striping.

PS:

HIGHWAY WIDENING AND IMPROVEMENT DEMONSTRATION PROJECT
For 80 percent of the expenses necessary to carry out a highway project between Paintsville and Prestonsburg, Kentucky, that demonstrates the safety and economic benefits of widening and improving highways in mountainous areas, $3,400,000, to remain available until expended.

I was noticing that the Michigan Left has made it to Point Pleasant Beach, NJ.  The NJ 35/ Broadway intersection which once allowed a left turn from SB NJ 35 to EB Broadway via a left turn signal is eliminated with motorists being required to continue on NJ 35 further and turnabout via a u turn ramp.  I am assuming the Manasquan River Drawbridge back ups had to do with that decision, but nonetheless qualifies as one in a state that loves its jughandles as solution for left turns on divided (and some undivided) highways.

Also I have seen that Arkansas set up in GA between Baxley and the Satilla River with US 1 being a four lane highway with a paved median.  No center turn lane is used either.  Just two double lines spaced apart 6 feet from each other. 

Even US 1 between Florida City and Key Largo is two lanes mostly with an occasional passing area that has a paved buffer in the middle.  Where its okay to pass it would appear to have a broken double line instead of the usual single broken line because of it.  In fact I was confused back in 90 when I drove to Key West for the first time.  It appears to resemble contraflow lane striping however being a two lane road it would not be used (or anyway at that time as contraflow evacuation was not yet invented).

Not anymore. It's now two lane divided.

Nothing.  It's a sarcastic joke.

Did you look at the entire length of the route?

West Virginia Twinning?

I've often called it "Virginia Twinning;" meaning that a parallel carriageway was built and the old carriageway was left as is.

Yes. Got an example of a portion with a two-way center turn lane?

Missouri already has the honor of being the namesake of the one flat side one hilly side twinned expressway.

Texas U-turn - special lane so 2 one-way ramps avoid the intersection just ahead of it
Texas barrier - more attractive than solid concrete

"Texas frontage roads" - a setup where both frontage roads are 2-way instead of 1-way, but there are still slip ramps to and from the highway in the middle. The "wrong" frontage direction has to STOP for exiting slip ramp traffic as well as entering "right-direction" traffic making a left.

Kind of like the frontage roads on I-55 in West Memphis/Marion, AR, area. I hate those.

I always joke about the "Michigan Expressway", which is the term I use to indicate a roadway that exclusively uses Michigan Lefts. 

These were originally known as "super-highways".  Even though the first Michigan Left wasn't constructed until 1967, the idea of turning right to go left was common practice ever since the first "super-highway" was constructed in the 1920's.  The idea was to construct major thoroughfares in the region that had medians wide enough to allow enough space for 2 rails of inter-urban transit.  It's a bit ironic that roads in the Motor City were originally designed with transit in mind.

The frontage roads on I-30 west of Little Rock and on US 67-167 north of North Little Rock used to be two way, but they were converted sometime in the '90s or '00s.  The two way frontage roads are hazardous.

Right. Many states have highways like this.  But is there any agreement on what to call this budget-upgrade process or the resulting divided highway?

We've been calling them "Missouri expressways" for years.

I've always known it as "Virginia Twinning". Perhaps the name preference is regional?

[bugo]

We've been saying "Missouri Expressway" since the 1990s.

There are several new Michigan Lefts on US 90 south of Lafayette. Everybody knows them as "J-turns." Also quite a few in the New Orleans area.

If you cannot go straight across US 90, they are not Michigan lefts.

OK, fine. But if you can turn left at the intersection, is that a Michigan left? That's what you can do at a J-turn: http://www.dotd.la.gov/administration/public_info/projects/la167_la699/images%5CJunction%20of%20US%20167%20%284-lane%20highway%29%20and%20LA%20699.JPG
