Defunct Interchanges

[Alps]

NJ Turnpike: Original Interchange 10
Original Interchange 11 (inside the current ramps)

[NE2]

Don't forget original 13 and original 17.

US 23/US 42, southside of Delaware, Ohio.
Old interchange...


"new" intersection

Boulevard Pie-IX (route 125) and Boulevard Henri-Bourrassa (former temp 25) in Montreal North is being downgraded to an intersection with signals, because a toll bridge has been built that bypasses it.

What's the rationale, though? Do the locals in the neighborhood not like having the interchange? Is it MTQ's idea of traffic calming?

Downgrading A10 I get, since that's in the middle of downtown. But this is not.

From what I heard, it was both for traffic calming and the residents not wanting a "big ugly concrete interchange" in the neighbourhood.

Ah yes, another case of the interests of many stopped by the interests of a few.

To be honest, this is probably justified in light of the new A-25 bridge.  It's the last interchange before QC 125 becomes a surface street, and looking at the street view, it behaves more like a surface street with a random interchange here anyways.

This folded diamond interchange between WI 33 and CTH LL in Port Washington, WI was recently demolished and replaced with an at-grade intersection.  One can see the construction to that end in the aerials.

It was built when CTH LL was the US 141 bypass of Port Washington.

WisDOT is planning on relegating this half interchange between I-94 and Willow Glen Rd in Jefferson County to the history books in the not-to-distant future.

Can't find the documentation regarding that plan at this time, but I know I read it somewhere from WisDOT.

Don't forget original 13 and original 17.

Not as noticeable as original 7.

[Sanctimoniously]

No one's mentioned Exit 250 and 251(?) off I-10 east of New Orleans yet?

[HazMatt]

They closed Exit 131 (Bus. 16) on I-40 in NC when the new NC 16 opened up less than a mile east (exit 132).

I remember passing that 2 years ago when my brother and I were running around NC while attending the Coke 600.  I wondered what the deal was.

Thanks.

I honestly cannot remember if there was once an Allen Ave/Linwood Ave exit in Shreveport along I-20 before I-49 was completed. I think there was and it got replaced, because Linwood now turns into Pierre and is attached to Lakeshore Dr exit as 17A.

In Dallas, Trinity Mills on 35E became overridden by the George Bush.

North of Fort Worth there used to be a turn around 35W north exit when going south from Denton, and now I'm guessing its now the TX 170 or Heritage Pkwy exit.


Don't know if these 3 examples really apply as "defunct" so much as they are replaced in the same spot

[TheStranger]

A couple of California examples:

- Jacinto Road at southbound Route 99 in Elk Grove, which existed when that section of freeway was built in the late 1950s:

Some of the grading remained in 2002 (but has been overgrown since).

- Bayshore Freeway (US 101) at Route 82 (Monterey Road) in South San Jose, bypassed in 1982 (built in the late 1940s).

Hwy 400 got once former ramps who connected to Wilson avenue for and to northbound traffic north of the Hwy 401 interchange http://www.thekingshighway.ca/PHOTOS/Hwy400photos.htm

[Beeper1]

The original Saco interchange on the Maine Turnpike, which was abandoned when the I-195 interchange was built just up the road, now leads to a hotel (though only from northbound, the overpass was demolished when the turnpike was widened in 2004). 

In Boston, the old Central Artery had a number of stubs of former on/off ramps that were torn down over the years.  Some were even torn down only a few years aftter the road was built in the 50s.

On I-95 in NH there used to be an interhcnage with now-defunct NH-51, just sout of the current NH-101 interchange/toll plaza.  The old ramps are now service access roads.

[deathtopumpkins]

Do you mean NH 27? It crosses 95 just south of the 101 interchange.

[PurdueBill]

Do you mean NH 27? It crosses 95 just south of the 101 interchange.

All the route numbers around there have changed a lot over time--NH 101 used to go via what is now NH 33 into Portsmouth, and NH 51 was the number for what is now the easternmost part of 101.  27 was extended over old two-lane 101 as expressway portions of 101 opened.  The road in question may have been 101-C at the time the interchange with the Turnpike opened.

The historic aerials site has a reasonably good shot of the original interchange, which is similar to today's in that the ramps surrounded the mainline toll plaza.

Addition: Indeed the old topo shows that the original route number intersecting the Turnpike at the old interchange was NH 101-C.

[deathtopumpkins]

Ah, I knew 101 originally used nearby highways but didn't know the old numbering.

And now that I reread the post I see it was "now-defunct NH 51".

Oops.

[english si]

A few British ones: The original M4 Junction 8 (most traces of destroyed when widened), The original southern end of the M74, defunct M8 junction, defunct M54 junction 5 (you can see that the road used to be 6-lanes between here and the current junction 5. Slip roads overgrown).

Some of the more blatant temporary termini, where the scheme ended, but no permanent junction was planned at the location. M90 Temporary Terminus, M1 Temporary Terminus, M77 Temporary Terminus, A1(M) Temporary Terminus

In Boston, the old Central Artery had a number of stubs of former on/off ramps that were torn down over the years.  Some were even torn down only a few years after the road was built in the 50s.

The original Central Artery opened in 1959; the ramps that you speak of were torn down during the mid-1970s.   

The old High St./Congress St. off-ramp (Exit 22) from southbound I-93 was relocated in the early 90s to allow for the expansion of the International Place complex.

[vtk]

US 62 in Columbus (now also I-670) used to have a parclo at Cassady Ave and a diamond at Stelzer Rd. Both were removed when the International Gateway interchange was built between them (circa late 80s I think).

Those closed interchanges puzzled me back in the 1990's.  Was there a zombie infestation being walled off?  LOL!  I'd love to know the story.

I believe the connecting roads, and related development, was never built.

The Cassady/17th Ave interchange got rebuilt into the current Cassady/International Gateway interchange as part of the I-670 construction.

That was to have been a housing development some time back (long before Katrina). One of my professors at LSU told me that Lady Bird Johnson was one of the investors in the project.

Without knowing the history of I-510, could the two interchanges have been part of the original traffic flow for Six Flags?  Maybe the development was tied to the amusement park's existence (future hotels, gas stations, etc)...
