Title: 'Shortest' interstate off ramp
Post by: papakilz on May 24, 2017, 08:27:08 PM
I thought I read once that Exit 339 on northbound I 75 in Mackinaw City, MI is the 'shortest' off ramp in the interstate system.  There is a gradual slow down lane which ends with a 90 degree turn to a STOP SIGN!  Any clue as to whether or not it truly is the shortest off ramp or not?

That is pretty short.  I immediately thought of the Grimes Exit (15) from I-78 in Pennsylvania:

US-22 & I-78 & Frantz Rd, Bethel, PA 19507

I-95 Exit 51 for US 1 in New Haven/East Haven both directions

Northbound (long exit lane, but here's the ramp, which hilariously spans 2 municipalities and even has an exit tab similar to those of the GSP)

https://goo.gl/maps/VuYMSU9fTK52

Southbound (same deal with the exit lane)

I agree with sbeaver44 because the southbound ramps are a bit longer than any of the ramps at Exit 15 on I-78.  Also some of the I-85 in SC ramps between Spatanburg and the NC/SC state line could qualify.  They have a similarity to the Exit 51 ramps described above.

I think a problem with trivia such as this is that you'd need a very precise definition of "exit ramp" - e.g. where does the deceleration lane end and the ramp begin?

I think the Mackinaw City ramps listed above probably do win the prize of most dramatic exit ramp of those listed above (note the 15 mph advisory speed and the stop sign that's arguably within the I-75 right-of-way), but depending on how you define "ramp", perhaps I-87 NB Exit 14 in Yonkers (https://goo.gl/ZQ9uwh) is a contender.

There is essentially a 'RIRO' intersection on WB I-80 along the Delaware River in New Jersey.

Also, there are numerous 'RIRO' access interchanges along rural interstates in Wyoming.

I am pretty sure that most of them have been fixed, but LA (and most of what eventually became CASR-99) was famous for entrance ramps effectively being "holes in the fence with a 'FREEWAY ENTRANCE' sign". A number of exit ramps on CASR-99 north of Madera (some in San Joaquin and Sacramento Counties come to mind) are still like that now. CASR-99 is not an interstate, but I am fairly sure that not all of the I-5, I-405, and I-110 entrances in LA have been fully upgraded.

As for exit ramps, a number of exits from I-35 in Austin (and probably the rest of Texas as well) dump you almost immediately onto a frontage road. A lot of those have an extra lane for a little while but often not very. Now, the frontage road is often identified and being part of I-35, so there is a definitional question of whether you have truly "exited" I-35.

Scroll a little further north from the Mackinaw City ramp, and you can see that the state of Michigan built the visitor center for Fort Michilmackinac State Park under the Mackinack Bridge..

Agree that the exit on the westbound side is bad. 

Though it might be worse on the eastbound side (https://www.google.com/maps/place/39%C2%B038'59.3%22N+78%C2%B045'19.8%22W/@39.649814,-78.756582,18z/data=!3m1!4b1!4m5!3m4!1s0x0:0x0!8m2!3d39.649814!4d-78.755485).

These exits are now part of I-68, but were built as part of the Cumberland Thruway, a section of non-Interstate U.S. 40.

There's a watermarked 1966 image of the Cumberland Thruway's bridge over Wills Creek and adjacent elevated highway under construction from the Baltimore Sun online here (http://baltimoresun.imagefortress.com/search/asset_details/1523350?page=16&query=%40folder_extended_description+%221-2-+%7C%22&results_index=23).

Because Pennsylvania.  Though between I-79 at Washington, Pennsylvania and New Stanton is probably worse, though between Breezewood and the Maryland border is pretty bad too (and as a bonus, has a posted 55 MPH speed limit and predatory PSP speed limit enforcement).

This spot in Columbia, NJ is probably the worst. Only westbound, but it's essentially a RIRO as mentioned above. What's worse, there's a truck stop that exits westbound trucks onto the highway at this interchange. Not safe at all.

Yeah, that's definitely not built to interstate standards. Google directions show that ramp as being 256 feet, but it looks more like 200 ft or even less.

I-25 going over Raton Pass in New Mexico and Colorado has some very short exit ramps, such as this one:
https://goo.gl/FLdgLs (https://goo.gl/FLdgLs)

Here's one along the same stretch of I-25 that I think is even more scary.
https://goo.gl/Uxpzdf (https://goo.gl/Uxpzdf)

If I recall correctly I think I-40 in the Smoky Mountains of North Carolina has some really super short exit ramps too.

I-4 in Deltona on the WB ramp to FL 472 as originally it was a trumpet interchange converted to a half diamond/half folded diamond.  Its very short and with a stoplight at the end.

I-4 WB at Michigan Street has too short of a ramp for the traffic that uses it.  It mainly used by those transferring from the freeway to nearby Orange Avenue even though the previous Kaley Street (now closed until the I-4 ultimate is completed) ramp gets you to Orange Avenue with a backed up ramp due to it once being a cloverleaf and having no end ramp signal.  It used to boggle a lot of people why drivers would choose Michigan over Kaley as the Michigan ramp has a 7:30 left turn as supposed to a loop ramp at previous Kaley, but nonetheless they chose to over capacitate the Michigan ramp instead of using a free flowing ramp with no hard turns.

In remote areas of the country they have direct turns like that.

Huh?  You mean with M-108 NOT there?  It's been decommissioned for over 6 years now.

But either way you meant it, the reason for that exit is to get to the tourist attractions in the area, primarily Fort Michilimackinac.

The saddest point of that stretch is that #2 on the listing of shortest exits may be several hundred yards northwest for the eastbound version of this exit 346C.  Personally, I dislike the eastbound version more due to the massive lane switching for the next exit 347.  (All I-76 traffic has to "exit" from the right lane to stay on the I-76 approach to the Walt Whitman)  What a mess that stretch is.

Now, here is a true Honorable Mention.

Kentucky Parkways and their underpass toll booth ramps.

Ramp itself is long, but the merge area is extremely short. These will not be on i-69 when it is offically signed.

Until you realize what happens if you have high speed traffic and trucks converging on it. US 412 at Ponca City OK has that issue.

Yeah, that kind of crap is just ridiculous. The only reason more crashes don't occur is due to low overall traffic levels. Such "cloverleaf transitions" would be disasters in busy, urban areas.

Check out this "cloverleaf transition" near Tacoma, WA. Similar length to your example: https://goo.gl/xitNpT

I was wondering why the exit ramps on the Western Kentucky parkway were so short. Now that the tolls are all removed, they're unnecessarily abrupt.

Although in order to fix that, they'd need to re-toll them to pay for it....
