Urban interstates that end abruptly

[Hot Rod Hootenanny]

Not interstates, but Youngstown,Ohio has two in very close proximity, with an expressway-like four-lane divided US-422 (speed limit 50) without an exit ramp running smack dab into Oak St., where you must turn left to proceed on 422. It was designed that way, as there were never any plans for the expressway to go beyond that.

Just north of there another four-lane divided expressway carries US-62 but dead ends abruptly at Albert Street, where again you must turn left to remain on the US route.  This was intended to proceed further in an eventual northeasterly direction to hook up with I-80 in Hubbard Township, thus the name of the ill-fated and never-constructed "Hubbard Expressway."

Truthfully, I do not understand why Madison Ave (aka US 422) ends at Oak St instead of seamlessly transitioning into US 62 (and the Eastern quadrant of the Y-town loop)

Langford Parkway in south Atlanta was to be I-420 but just ends up dumping onto Lakewood Avenue just east of its junction with I-75-85.

I-420.

Perhaps GDOT didn't go through with that after realizing they would have a lot of stolen signs on their hands.

I wouldn't be suprised if a ton of I-69 shields had to be replaced because of theft already

As far as I know, here in Houston there hasn't been. Maybe in rural areas.

From what I know, Michigan marks freeway entrance ramps with a BGS, so it's hard to find an I-69 shield unless it's a reassurance one on the freeway
Indiana is inconsistant. One intersection, they'll use a BGS. The next, it'll be ground mounted shields. The one after, it'll be overhanging cut-out shields. With this, it's a possibility there's a stolen I-69 shield at some point somewhere.

Do any of the OH-420 signs get stolen frequently?

I read somewhere that mile 420 signs in eastern Colorado kept getting stolen so they changed it around to where it now says 420.1 and moved it accordingly

[hotdogPi]

Last I checked (which was a few years ago), there is no 66.6 mile marker on US 1 in Massachusetts (Topsfield/Danvers). Mile markers are every 0.2 in that region.

Probably more along the lines of a 419.99 mile marker sign, just like how they do 68.99 mile markers so there is no reference of said numbers at all.

I think the only standalone OH-420 shields are at the OH-163 intersection, and also southbound just past Libbey Road, and anytime I've driven through the signs were there.  Most recently was a few months ago.

What about I-78 and I-495 in Manhattan? Those just dissolve into city streets shortly upon entering. And if we're counting non-interstates, the Woodhaven Road freeway in Philadelphia ends as a driveway into a business parking lot.

Truthfully, I do not understand why Madison Ave (aka US 422) ends at Oak St instead of seamlessly transitioning into US 62 (and the Eastern quadrant of the Y-town loop)

First, remember that these expressways (and many others) were conceived, planned and engineered in the 60's and early 70's, when left exits, closely-spaced entrance/exit ramps, and other design characteristics such as this intersection/ending were considered acceptable and/or desirable.

In this specific instance, one of the major movements is for traffic to continue on US-422 east, which theoretically could be accomplished with what you suggested by including an exit ramp off US-62 at Oak Street.  But within the existing footprint, it becomes a major engineering challenge as there is very limited space which is further complicated by the terrain and the necessity of the bridge on 422 spanning both the creek and railroad tracks immediately prior to the intersection of the two mainlines.

That would also create a weave issue with US-422 traffic that wanted to proceed to US-62 southwest, along with US-62 southwest traffic that wanted to exit to US-422 east--had the US-62 segment been completed beyond Albert Street, which it never did and never will be.

I would surmise that planners and engineers considered moving the US-62 mainline and ROW to the east to alleviate those concerns in order to accommodate said exit ramp, but there were (and are) two major community resources on Oak Street--a school and a church--that stood in the way and that would have had to come down.

It's interesting to note the over-engineered/over-built interchange here, whereby US-62 northeast traffic exiting to US-422 west follows an exit ramp that goes under Oak Street (like the mainline), but then to avoid a weave situation is bridged over the loop ramp from US-422 east to US-62 northeast.  Again, had that expressway been completed beyond Albert Street as planned, then it makes some sense.  But it never came to pass.

A poster in another thread asked, given its size why Youngstown and its surrounding area has so many freeways and expressways.  Perhaps the answer, and the existence of this overbuilt interchange is because Youngstown native J. Phillip Richley was the Ohio Department of Transportation Director during the late 60's and early 70's.  He later served as Youngstown mayor for two years in the late 70's.

I spent some time in Savannah last week while making my way up the I-95 corridor, and I thought the east end of I-16 happens rather suddenly and with little warning.  The first mention of I-16 ending is here, and then "exit 167B" turns out to be nothing more than the eastbound lanes suddenly dumping onto Montgomery Street.

Yes those would also apply as they were supposed to be continued to serve the city before special interest groups came into the picture.

From what I know, Michigan marks freeway entrance ramps with a BGS, so it's hard to find an I-69 shield unless it's a reassurance one on the freeway
Indiana is inconsistant. One intersection, they'll use a BGS. The next, it'll be ground mounted shields. The one after, it'll be overhanging cut-out shields. With this, it's a possibility there's a stolen I-69 shield at some point somewhere.

Indiana's I-69 signs actually are pretty consistently marked at interchanges and along the highway itself with both BGSs and ground mounted shields. In any case, the vast majority of I-69 signs are intact. Once in a blue moon would one sign actually be missing and even then it's more likely the case that the sign was simply damaged by a vehicle than by theft.

I've never noticed any issues with missing signs for KY 69, KY 420, or the new I-69 in Kentucky.

Non-interstate example (but is an 'extension' of an interstate): BC 99 in Vancouver after it crosses the Fraser River, dropping onto Oak St.

Last I heard, even the 419.99 signs on 70 had been stolen.

Those got stolen pretty quickly every time they went up, so CDOT stopped replacing them. Ditto with the 419.99 signs on other roads which are that long.

i-165 in mobile just dies and turns into water street downtown.

I-78 Freeway ends before that even. The freeway ends at a signalized intersection with Jersey Avenue in Jersey City, NJ.

Which itself is a trivia question answer. I-78 is the only Interstate other than I-70 to continue through signalized intersections, because the one-way pair it follows in Jersey City has several of them.

I thought I-676 had a signal in the middle.

Apparently the surface segment in Philly may not officially be I-676?

[bwana39]

I-45 crosses the Galveston Causeway and transitions into SH-87 a first three lane urban arterial with sloughs of traffic signals .

At this point, I-49 drops off into two one-way streets at Lafayette and ends at a tee with US-71 north of Texarkana. Both of these are temporary ends, but the south one at Lafayette was seemingly the permanent one for over a decade.

I-49 also drops off just north of I-20 into what is little more than a neighborhood street.

676 is officially discontinuous. The segment connecting to I-76 west of downtown ends at I-95, then you have the Ben Franklin Bridge/NJ segment.

You've offended poor I-180 in Wyoming!

As for I-676, I thought that was recognized by one DOT but not another.  You could even make the "discontinuous" argument for I-70, given the way it's signed as US 30 TO I-70.  Of course, if you let signing be a deciding factor, that hurts the case for I-78, because last time I checked, it ceases to be signed where the freeway ends.

Let's face it. I-180 in Wyoming is not an Interstate, it's just signed as one.
