Defunct Interchanges

[roadman65]

Interchanges that once were, and now closed either with ramps removed or still left in tact.


Lumberton, NC- I-95 and Original US 74 diamond interchange that was closed when the current I-74 & new US 74 alignment was built and finally opened.

Bridgewater, NJ-  US 202 & 206 at Garetson Road had a half diamond that was closed in 1987 when the Commons Way interchange opened.  Also, the EB US 22 to SB US 202 & 206 SB ramp was removed  at the same time when the nearby interchange was reconfigured.  All interchanges here were added, deleted, modified, etc. when the Bridgewater Commons Mall opened.

In Queenston, ON the ON 405 and Niagara Parkway interchange was permanently closed in 2006 with its ramps, nearest I can tell via google, have been removed.

On I-4 in Orlando  many decades ago before the current FL 408 was built, there used to be a complete interchange with Gore Street.  Then later a half diamond was WB on and off until recently when FDOT removed the WB I-4 offramp during a major construction project to add new ramps to and from South Street.  In addition the EB ramp to Robinson Street and the WB ramp to South Street were also closed. However, the South Street ramp was closed long after the project finished when the new Amway Center opened.  The ramp was closed due to South Street being closed so workers could build both the arena and parking facility ( on both sides of South Street west of I-4) and for some reason never reopened once the new Amway opened along with South Street.

In Kunhsville, PA an interchange was removed between US 22 and a local road to construct the current US 22 and I-78 interchange.  Motorists going EB on US 22 must use PA 100 and the old US 22 to access Kunhsville and WB traffic must exit solely at old US 22 to access the town proper.

I-80 and I-480 at the foot of the Bay Bridge in SF. Used to include ramps to the former Transbay Terminal.

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.

A few in Wisconsin:

-US 10/41 (I-xx)/WI 441 'Bridgeview Interchange' between Appleton and Neenah:
https://maps.google.com/?ll=44.214264,-88.473544&spn=0.008843,0.013797&t=k&z=16

Lake St to the south originally had NB on/SB off connections to the US 41 C/D lanes.  It was disconnected from the interchange and bridged across as a local street in the late 1980s/early 1990s.

-US 41 (I-xx)/Main St (former WI 175) - Fond du Lac:
https://maps.google.com/?ll=43.743104,-88.449748&spn=0.008914,0.013797&t=k&z=16

Had a very odd late 1940s-era 'inside rotary' style interchange that was removed when the US 151 bypass and its US 41 interchange were built in the early-mid 2000s.

-I-43/County 'PP' (former WI 28) - Sheboygan:
https://maps.google.com/?ll=43.742158,-87.760463&spn=0.008914,0.013797&t=k&z=16

This tight interchange that long pre-dated US 141's 'promotion' to a full interstate used very tight ramps between the road and the railroad.  It was removed when WI 28 was rerouted to the south in the mid-late 1980s.

US 41 (I-xx)/Cecil St/Green Bay Rd - Neenah:
https://maps.google.com/?ll=44.167922,-88.485131&spn=0.00885,0.013797&t=k&z=16

Cecil St is the east-west street, Green Bay Rd the major north-south.  When US 41 was upgraded from the former two lanes (Green Bay Rd) to four lanes in the late 1950s/early 1960s (freeway to the north, surface four-lanes divided to the south), an off ramp connection from NB US 41 was left in place for Green Bay Rd at Cecil St.  This was removed as redundant (the WI 114/Winneconne Ave interchange is only a couple of blocks to the north) when the highway to the south was upgraded to a full freeway in the mid 1970s and Green Bay Rd was then extended to the south from the defunct ramp as a frontage road.

The PA Turnpike has a few. The old Morgantown (10/23/176) Interchange had its bridge over the Turnpike removed, and later the entire thing north of the Turnpike was ripped out for a parking lot that's (still) unused.

The old Reading (222) Interchange ramps are used as non-public access ramps, as well as a local street serving some businesses.

[mightyace]

Yes, and so does the Ohio Turnpike.  Most interesting example is the I-76/80 "Bump"

https://maps.google.com/maps?ll=41.106681,-80.827961&spn=0.017656,0.045447&t=h&z=15

Originally, the exit here was at then Ohio SR 18 (now county 18) and were abandoned when the 76/80 interchange was built.  However, those ramps remained in place and the ones to "County 18" a.k.a. Mahoning Avenue are used again in the "extension" of the interchange.

If you look closely, you can still see remnants of the original turnpike end of the interchange including the still extant bridge over the turnpike that carried traffic to and from the EB lanes.

This is not the first time the Ohio turnpike has done this.  Witness the I-71/US 41 Turnpike interchange.

https://maps.google.com/maps?ll=41.337751,-81.822073&spn=0.008797,0.022724&t=h&z=16

There are new connections at the toll booths but the original ramps were reused and you can still see the ghost ramps of the turnpike connection.  Back in the 1970's, the trumpet as US 41 was still there but it's been removed, though again, you can see where the ramps were.

A more recent "combo" is I-77/US 21 a few miles to the east eliminating that "Breezewood" situation.  However, much more of the original interchange was reused.

https://maps.google.com/maps?ll=41.272662,-81.628375&spn=0.008805,0.022724&t=h&z=16

In the overhead and streetview, parts of the old toll booths are still visible, though I haven't been that way recently and can't say whether or not that still exists.

[DandyDan]

I assume the old exit for Ellsworth AFB in South Dakota counts here, even though they built a new interchange just a mile down the road.

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.

What comes to mind in Connecticut:

I-84:
- old exit 11 and 12 in Newtown, between the CT 34 interchange and the Housatonic River; removed c. 1973 with reconstruction
- old exit 91 (Forbes St), East Hartford, between CT 15 and I-384; removed c. 1985

I-91:
- two ramps to/from Charter Oak Bridge and points north; removed c. 1991
- Bina Ave. onramp to I-91 north, Windsor, removed c. 1985 (no exit number, since not an exit)
- "exit 39 & 41" used to be two separate diamond interchanges
- exit 43, Main St (SR 510), E. Windsor, removed c. 1988 with I-91 widening

CT 2:
- exit 6 to/from points east removed c. 1990 with widening
- exit 14 in Marlborough: 3-level interchange with stub ramps removed when CT 66 freeway was cancelled, 1976*
- exit 26 in Norwich: this was a grade-level crossing with Yantic Lane. Removed c. 1998

CT 15:
- exit 30, Butternut Hollow Road, grade crossing, removed 1955

* not true, just messing with ya

Coal Canyon Road and CA 91 in the Santa Ana Canyon.

[Brandon]

A number of the "rapid-fire" exit ramps on the Kennedy Expressway in Chicago's Loop have have their left-hand entrances removed.

[InterstateNG]

I-94 in Ypsilanti, MI used to have an interchange with Grove St, which would have been exit 184.  Eliminated sometime before 1973.

[Eth]

There was once an exit from I-75 northbound to its frontage road just before I-285 on the south side of Atlanta.  It was numbered as exit 79 and removed sometime before the milepost-based exit numbers appeared in 2000 (if it existed today, it would likely be 237 with some letter suffix).

Here's a screenshot of Google Earth imagery from 1993 showing the ramp.  The next oldest image it has is from '99, and it was gone by then.  It looks like it may have been removed to make way for a longer on-ramp from Forest Parkway (exit 78, now 237).

[US71]

I-40 had a partial interchange with AR 25 at Conway (EB exit only, no on-ramps). It was removed in 2006, when a new full interchange was built about a mile west.

[vdeane]

The old I-90/I-690 interchange (which had a traffic light on I-690) before it got moved a mile to the west.

[Revive 755]

* MO 370 at Taussig Road - Replaced with a new interchange to the west.  Old grading for one of the ramps is still visible:  http://maps.google.com/maps?hl=en&ll=38.779589,-90.413189&spn=0.007067,0.016512&t=h&z=17

* US 40 at Laclede Station Road in Richmond Heights, Missouri - Removed due to spacing issues when this section of highway was rebuilt.

* US 40 at Oakland in St. Louis - a former half diamond with WB on/EB off; removed when this section was rebuilt.  There was a design alternative which would have kept the EB exit as a braided ramp, but the cost and ROW impacts were too great IIRC.

* The little spur freeway from US 40 to Chouteau in St. Louis used to have a 3/4 diamond with Vandeventer; removed when the Chouteau viaduct was replaced and the spur was truncated to Vandeventer.

* US 40 at Vandeventer:  Historic Aerials is showing a half diamond (EB on/WB off) here; seems to have been removed when the WB lanes were put on the viaduct over the EB lanes.

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

Exit 103 along I-94 in Emmett Township, Michigan, was removed a few years ago and replaced with a new exit 104 to the east.

[pianocello]

Exit 103 along I-94 in Emmett Township, Michigan, was removed a few years ago and replaced with a new exit 104 to the east.

Exit 104 had always been there, but the connector north of I-94 between 11 Mile Rd and M-96 is new.

[ibagli]

There used to be a strange little interchange on the QEW in Oakville, ON betweeen Burloak and Bronte for the service roads. Three of the ramps were taken out around 2000, but the westbound exit remained until 2008. The ramps and bridge are completely gone now.

Exit 104 had always been there, but the connector north of I-94 between 11 Mile Rd and M-96 is new.

An interchange in the general spot was there before, but it was slightly further west, and numbered exit 103. Look on the satellite view, and you'll see the remnants of the one loop ramp removed. Searching online finds old newspaper articles referencing exit 103 in relation to detours and road closures.

Exit 103 was removed to eliminate the weaving movements with the loop ramps from Exit 104. There is a project this year which will extend the left-turn lane along Michigan Ave from 11 Mile to Wheatfield Dr. As part of that, I surmise the remnants of 103 will go away to make way for the expanded pavement. There's also a realignment of the WB onramp from Exit 104 as part of this project, and as the satellite imagery which Mike linked to shows, the EB onramp was realigned last year.

Although not defunct yet, once the Sargent Road interchange reconstruction is complete, Exit 144 will cease to be.

[ftballfan]

Didn't the Grand River Ave exit from I-96 (Exit 90) used to be Exits 90AB?

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