Title: Interchanges That Never Were
Post by: Brandon on October 25, 2018, 11:24:45 AM
While driving along the Eisenhower Expressway (I-290) the other day, I noted something very odd about the overpass for East Avenue in Oak Park, Illinois.  The eastern face of the overpass was built such that it flares out as if it was intended for an interchange.  I did some research, and there was never an interchange of any sort at East Avenue and the Ike.  However, it does appear to have been built to have a partial interchange to/from the east.

It's a bit off that the Ike should be so wide for the whole stretch between East and Austin as well, considering that it only widens for a short distance for Harlem.  The other bridges with interchanges (Harlem and Austin) flare the same way the East Avenue bridge does.

The only thing I can recall that's close to this is something I know you're familiar with, Brandon:  the I-72/US51 interchange on the north side of Decatur anticipating an I-39 extension.  The ghost ramps have been removed, but you can still see the separation of the carriageways to allow for the flyover ramps.

It might have something to do with the location of the railroad right-of-way.

Ultimately it depends on how you're defining "groundwork was laid."  There are instances where ghost ramps were actually built, instances where land was graded for the interchange, instances where the road was merely built to accommodate the interchange...There are numerous instances of those. Hell, there were (are?) ghost roadways at KSC for the Mobile Launcher Platform to travel to a launchpad that was never built.

It seems like NJ 18 had a fully built interchange including movements for south of NJ 138. I don't know if they were ever fully open, but the road itself was never extended and probably never will be.

The structure is clearly visible on 1962 and 1963 historic aerials and there was a little more structure to the stub present back then...

Two examples I can think of, one, where an interchange was intended but never built, and the other, I have no idea.

US 26/ORH 26 between Gresham and Sandy, where the never built Mt Hood Freeway was to tie into the Mt Hood Hwy:

I can think of two more East Coast examples:

The I-84/CT 9 stack interchange west of Hartford, where a planned but never built extension of the latter highway was once envisioned to connect to the north of there.

Also, the I-95/I-70 interchange in Baltimore, which featured a long ghost ramp for the EB/SB movement that was removed in the late 90s.

I-84 Exit 46 in Hartford, CT (https://www.google.com/maps/place/40%C2%B045'14.8%22N+74%C2%B022'55.6%22W/@41.7616857,-72.7014168,251m/data=!3m1!1e3!4m5!3m4!1s0x0:0x0!8m2!3d40.754099!4d-74.382107?hl=en-US) was intended for the CT-189 expressway, I believe.  No long ramps but definitely some stubs.

Here's something similar in Utah: I-215, Exit 25. (https://goo.gl/maps/MPqcxqQk9JN2)

The canal and street to the east of the interstate were rerouted to allow for a loop ramp from eastbound 2100 North to northbound I-15. This was associated with the proposed Bangerter Highway, which would have run north along what was then the west side of the airport and east along 2100 North. The proposed extension past I-80 never happened, and it's no longer possible because the airport expanded west in the early 1990s, when Bangerter was built to tie directly into the airport access loop. Contrary to what many maps (Rand McNally, for one) continue to show, there has been no way to drive around the west side of the airport on public roads for at least 25 years.

I-680 at future/cancelled CA 238 in Fremont, CA. An unused overpass was demolished about 10 years ago.

I-91 at I-291 in Rocky Hill, CT: same situation, where an unused overpass was removed when I-91 was widened.

CT 15 at exit 43 (Sherwood Island Connector extension) in Westport, CT. No ghost ramps exist -- this i/c was never built

Supposedly a section of CT 8 was designed in anticipation of a CT 72 freeway connection; but I've never found exactly where that was.

Several years before the current I-93 Salem to Manchester widening work began, some of the bridges south of Exit 4 in Londonderry were replaced with new ones that were wider.  This wasn't advance work for the roadway widening project, but was done in anticipation of a new exit that would have been built off of I-93 had the Mall of New Hampshire been constructed in Londonderry (the original proposed site) instead of in Manchester.

US 101/Hollywood Freeway near the Melrose Ave. interchange in east Hollywood: the carriageways, each on viaducts at that location, were widely spread to accommodate the CA 2/Glendale/Beverly Hills freeway (long deleted), which was to cross US 101 on a more or less E-W axis, complete with LH entrances and exits to minimize property taking on the perimeter.  Of course, it never came to pass with the CA 2 freeway's truncation to its present SW end at Glendale Blvd. in Echo Park and the cancellation of the Beverly Hills Freeway (primarily due to both expense and NIMBY factor).  The space under the freeway -- at least the last time I came through there circa 2012 -- was occupied by a storage facility.

Also, the I-95/I-83 interchange in Baltimore, where the lane drops were visible on the viaduct where the ramps would enter and leave I-95; now the viaduct is being widened to 4 thru lanes each way thru the unbuilt interchange area.

I remember once seeing a screencap from a videotape of a drive through one of these interchanges (don't know which one) that showed ghost ramps rising into the air, but I can't find it for the life of me.

I-41 and County A near Appleton WI.  The sound walls were pushed back to show where the right-of-way was bought and to accommodate the ramps that were never built.

The east-west part of US (now 'I-') 41 between Appleton and Kaukauna has two additional 'never built' crossroad interchanges besides at Outagamie County 'A' where ROW was preserved when the highway was first built in 1960:

- Meade St
- Rosehill Rd

WisDOT was looking into building an interchange on US (now 'I-') 41 at County 'A' about 20 or so years ago, this to alleviate through traffic problems in the area, but nothing ever became of them (they were looking at a lot of improvements as far north as the Black Creek area as part of this) and with the highway's subsequent promotion to a full interstate, it is highly unlikely that any of those planned interchanges will be built in the foreseeable future, this due to interchange spacing requirements that are part of the basic design standards of the interstate highway system.

Also, if you check aerial images of the area, you'll notice some interesting angles in the area of Fieldcrest Dr and County 'CE' in Kaukauna.  When these routes were being laid out in the mid-late 1950s, a north-south WI 55 bypass of Kaukauna was proposed to run along Kaukauna's west edge, by the city's borders with Combined Locks and Little Chute.  That plan was dropped by the mid 1960s, but the lines were already set in the local development patterns.

The Crosstown would have been closer to/east of IL 50/Cicero Avenue.  I don't think the Crosstown got far enough along to get any ghost ramps.

On I-380 @ I-280 interchange in San Bruno there was going to be an extension where I-380 connects to CA-380 on the median but that was never made due to the opposition at the time and the Southern Crossing from I-380 @ US-101 but that's  been in debates for decades.

In Sacramento at the I-80/CA-51 interchange CA-244 was going to be extended into another freeway but CA-244 is only a ramp.

There used to be a section of CA-480 that had an abrupt roadblock due to CA-480 originally being used to connect to the Presidio Parkway formerly Doyle Drive though and that was stopped.

I'm more interested in those two ghost interchanges on I-70 east of the downtown area, the first at Indiana/Truman (I have no idea what its buildout plan towards Independence, MO was) and the other at 29th/Jackson (to feed into the Blue Parkway/MO 350?). What are the stories of these two unbuilt extensions?

I-495 (Capital Beltway) at the (never-built) Northern Parkway in  the Silver Spring area of Montgomery County, Maryland.  Years ago, under the original numbering system for Beltway interchanges, there were small signs stating that Exit 22 was a "future" interchange.  There was a fairly large bridge that was constructed to carry the Beltway over Northern Parkway which was removed about 2000 or 2001.

Details in a blog posting from 2014 here (http://www.aroundfourcorners.com/2014/04/the-northern-parkway.html).

Newport freeway in Newport, De. It was supposed to go around the back of wilmington, but for whatever reason it was canceled? Also Route 4 in Newark, De was supposed to be a highway from Elkton-Newark Road & around the back of the city of Newark & suburbs probably making the city even bigger then it is now.

Part of a late '70s/early '80s plan for the "Southern Connector"**, a 4-lane at-grade roadway extension from I-189 tying into Battery St in downtown Burlington.  What you see is what got built before the discovery of far more contamination than expected along the Pine Street Canal first postponed and then scuttled the project.

The current plan (possibly to begin construction in the next year or two) will partly utilize what got built as a 2-lane parkway-style roadway that will extend up to Lakeside Ave just west of Pine St.

** - This project also completely redid the 189/7 interchange into its current configuration.  The original configuration was a trumpet interchange with 189 bridged over US 7 (instead of the other way around as currently exists).

At the southern end (https://www.google.com/maps/place/MD-147+%26+US-1,+Pleasant+Hills,+MD+21047/@39.5078735,-76.3813912,17z/data=!4m2!3m1!1s0x89c7de1e84dc9dd9:0xf543ab9d69e16fed) of the US 1 Bel Air Bypass in Harford County, MD, there is a wide segment of median and a grade separation of approximately 20-25 feet between each side of US 1. Although I've never seen a map or a diagram which confirms it, I believe this was intended to be the point where a proposed replacement of US 1 called the Perring Freeway was intended to join the bypass.

Further along the bypass, the awkward intersection where MD 24 joins US 1 was intended to be a large semi-directional interchange between the two highways. MD 24 was intended to proceed north beyond US 1; I've never seen a map or diagram of this route either so I don't know where it would have rejoined the current routing of MD 24, or what the interchange would have looked like. There are long-unfunded plans on the MDOT SHA books to use the ample site of the planned interchange to build a trumpet between US 1 and MD 24, and widen US 1 into a four-lane freeway between the southern end of the bypass and the intersection beyond the MD 24/924 interchange.

On the eastern side of the Baltimore Beltway, in Essex, MD, there is a very strangely shaped interchange (https://www.google.com/maps/place/I-695+%26+MD-702,+Rosedale,+MD+21221/@39.3284801,-76.48141,15z/data=!4m2!3m1!1s0x89c807bc3be5292d:0xea72a2554be95902) between I-695 and MD 702 at Exit 36. The Beltway was intended to follow MD 702 east of the interchange, travel down the peninsula formed by the north shore of the Back River, and cross the Back River at its mouth to the Chesapeake to rejoin the Beltway. At the point where it would have joined up, south of Exit 41, the median is very wide. Because the crossing was never built, I-695 has to follow the exit ramps that would have linked the Beltway with the freeway south of the interchange at Exit 36, and there are many unused underpasses, ramp stubs and carriageway stubs showing where the missing roads would have gone.

South of Exit 36, there is a sharp 45mph curve where the Beltway turns east. This would have been a link with the Windlass Freeway, a planned cutoff between I-95/895 and MD 43 White Marsh Blvd in Middle River, MD. The segment between I-95 Exit 59 and here was deleted, but not before the ramp stubs at I-95 Exit 59 and the short segment between this curve and Exit 36 were built.

I found out about most of these missing roads from MDRoads, Roads to the Future, and this forum. Someday I'd like to go in the SHA archives and see the plans for these roads and interchanges.

The only thing I can recall that's close to this is something I know you're familiar with, Brandon:  the I-72/US51 interchange on the north side of Decatur anticipating an I-39 extension.  The ghost ramps have been removed, but you can still see the separation of the carriageways to allow for the flyover ramps.
what about this??

I'm of the opinion that the segment of the Windlass Freeway between I-95 and this curve should be studied and eventually built. It would help relieve traffic on US 40 and MD 150 and reduce congestion on I-95 north and I-695. There's a sewage treatment plant along Windlass Run between the two freeways, so I wonder how much the local environment would be affected by the construction of a four-lane freeway.

Possibly.  The 1965 map suggests yes, but I've also seen planning maps from Frederick County that would be a definite no.

The idea of a Back River bridge there was not dead in 1964.  What was dead was the idea of using that bridge for the Beltway...if that was even a consideration.  As I noted above, I'm not convinced that was the case.

I'm more interested in those two ghost interchanges on I-70 east of the downtown area, the first at Indiana/Truman (I have no idea what its buildout plan towards Independence, MO was) and the other at 29th/Jackson (to feed into the Blue Parkway/MO 350?). What are the stories of these two unbuilt extensions?

IIRC, the Jackson Curve ghost ramps were for a feeder arterial, which then morphed into a short feeder freeway, which then morphed into a longer north-south freeway east of US 71 before being cancelled.  The Truman curve appears to have been originally for a short feeder freeway to US 24, and later for a continuation of the north-south freeway which would have gone north to I-35.  There some information on https://www.linecreekloudmouth.com/blog/kc-freeway-history/ (https://www.linecreekloudmouth.com/blog/kc-freeway-history/), and I think there was also a past discussion on it elsewhere in the forum.

Since these discussions haven't resolved it fully I haven't changed it yet.  Seems like the MD-702 route coupled with a river crossing made a continuous beltway route with no low-speed curves (there are three) as we have today with the segment of the Windlass Freeway and segment of the Patapaco Freeway.   The east end of the Patapaco Freeway has a major curve as it transitions into the Outer Harbor Crossing toll facility.

The whole eastern part of the Baltimore Beltway (MD-2 to I-95 north) has its oddities in alignment as well as in how it was developed.  Looks like it was cobbled together, both segmentally and in the widenings/dualizations.

Exit 45 (Flatbush Ave) was also supposed to be a CT 9 expressway connection to the Berlin Turnpike where US 5/CT 15 leaves the turnpike northbound.  The CT 189 expressway's original number was CT 9.

Exit 29 (CT 10 Milldale) was also supposed to be the north end of a CT 10 expressway to the New Haven area that would've either connected to I-91 at Exit 6 or to I-95 near Exit 43.  The plans were later truncated to be a connection from I-84 WEST to I-691, but that was also cancelled.

Speaking of the CT 10 expressway, there was supposed to be a northern component to it north of Plainville.  There would have been a stack interchange on CT 72 about where it squeezes from 4 lanes to 2 west of I-84 about a half mile west of the CT 177 exit.

Has anyone mentioned the Goat Path interchange east of Lancaster?

I believe that in Chicago, I-694 (the LSD upgrade that never was) was planned to end at the Ohio Street stubs to the north, and the Calumet/Stony Island Avenue ramps to the south. I also remember seeing I-494 appear in atlases for the same corridor, but remember it better for the Crosstown Expressway, and I don't know whether they were planned to meet anyway (probably not).

^ Rock Creek Parkway was never intended to be Interstate standard.  The freeway you're referring to (what would have extended "north" from the Whitehurst) was the proposed "North Loop", which at that point had morphed into the proposed K-Street Tunnel.

-  Cleveland, OH -- I-71 Exit 244/Denison Avenue.   

This wide-median section was where the Parma Freeway was to extend North to I-90 and SR-2/US-6 the West Shoreway & South to SR-3 near the Parma/North Royalton Border.  Only the short stub was built to connect I-71 with Denison Ave as a "T" intersection before NIMBYs killed it.

If you look at the Google Maps link, https://goo.gl/maps/37gweaWpvL42 you can see due north of the dead-end "T" intersection a section of I-90 with a not-as-wide median that was built to accommodate ramps to & from westbound I-90 at the very least.

-  Akron, OH -- I-77 Exit 138/Ghent Road.

A similar extra-wide median shows on this link https://goo.gl/maps/M4KTUUrRLqw as I-77 was to have turned southeast at this point, splitting from SR-21, and would have connected near the Miller/Ridgewood interchange in Fairlawn.

NIMBYs in Fairlawn nixed that idea and I-77 was routed around the majority of that more-affluent suburb of  Akron.

Albany, NY has/had a crapton, many of which have been repurposed.


Rochester, NY has a couple:


Syracuse has the I-481/I-690 interchange on the east side of town. Stubs/unused ramps to/from the east.

In Buffalo, I-190 was planned to have an interchange at Ferry Street. This was canceled early on, but there still is no Exit 10.

Going down to the Hudson Valley, the US 9W/NY 299 intersection in Ulster County has grading for a never-built trumpet interchange.

Also in New York, the north end of the Taconic State Parkway (at I-90/NYSThruway Berkshire Extension) has grading in place for a northward extension of the Parkway, with the existing interchange to be part of a double-trumpet.

(I'd love to see what the Parkway's ultimate buildout plans are/were.)

There's the interchange involving I-66 in Washington with that gorgeous, ancient button copy signage, which was supposed to link to I-695: https://www.google.com/maps/@38.897872,-77.0530464,3a,75y,173.45h,83.31t/data=!3m6!1e1!3m4!1smn18B3kxRlADWr_WijrPrw!2e0!7i13312!8i6656

Enjoy the picture while it lasts, as those signs were replaced this summer. I haven't been over there since they finished the work, but here's one of my pictures from August 24 when the work was underway:

Until the 80s or early 90s, that WAS more of a double trumpet. Northbound traffic used a trumpet ramp to the toll booths and bridged over graded lanes of the never-built parkway. SB traffic uses its original alignment, but NB was realigned to bypass the trumpet.

As far as buildout plans, I've seen three main ones:

Similarly, the I-390/I-590 interchange may have been a full stack if built as intended, but I have not seen plans.
There's a design of some kind shown in a 1970s era Rochester map I have.  Not sure how to share it here, though.

I completely forgot about this interchange that never was:   SR-11 near Columbiana (Youngstown), OH.

https://www.google.com/maps/@40.9004391,-80.7231274,1147a,35y,359.94h,44.7t/data=!3m1!1e3

You can tell in the overhead view that this was to be a full cloverleaf based on the distinctive foliage seen in the ROW.  This was to have been the interchange for SR 11 and either/both SR-14 and/or US-62  when the original plans in the 60s and 70s called for a limited-access highway connecting Youngstown to Canton. 

Short sections of that ill-fated expressway were completed around Alliance, Salem and Youngstown, but never got beyond that for whatever reason (likely funding), and was never connected/completed.

I believe at one time there was initial grading of the cloverleaf that has since been un-graded and returned back to nature, as the GSV indicates, but no concrete was ever poured nor bridge(s) built.

An interchange between SR 520 and the cancelled R.H. Thompson Expressway in Seattle was partially built. There were many ramp stubs and an unused overpass. Most of it has since been demolished, but 2011 Streetview has some interesting pictures:

I suppose you can't say "never" when it was only built a handful of years ago, but this Texas-T (is that still a techincal term?) for the I-5 HOV lanes in Lynnwood, WA was only half-built: https://goo.gl/K9rEBe

That's not even a "Texas-T", just a final HOV/bus connection to a local Park-and-Ride that passes over half of the freeway mainlanes. More like a "Seattle L".

This in New Jersey comes to mind:
https://goo.gl/maps/Hz1ecLFHknD2
An opposite scenario (stubs & overpasses for the intersecting road but not the highway itself) exists near Leola (Lancaster County), PA along PA 772 (https://www.google.com/maps/@40.0748841,-76.1794365,3a,75y,307.12h,70.82t/data=!3m6!1e1!3m4!1shM8HiDKdNb6t_TFJe50CyA!2e0!7i13312!8i6656) where the PA 23 (aka Goat Path) Expressway would've interchanged with it.

It's supposed to be a "T" eventually. That's why I said it was "only half-built". Right now yes, it's an L but you can clearly see in my link the northern extension stub.

Here's a partial one in Youngstown, Ohio:

https://goo.gl/maps/6wvNcuCD5Ys

A loop ramp off Williamson Avenue intended to carry US-62 traffic northeasterly on what's known as the Himrod Ave. Expressway.  The ramp area was engineered and graded, but never actually constructed.  US-62 runs north on Market Street, turns east on Williamson--and because this loop ramp wasn't built--then continues along Williamson; turns left (north) onto South Avenue, then enters the expressway via a short on-ramp eastward off South Ave.

That is correct.  Somewhere I have an old Milwaukee County map that shows the proposed route.  The end of the Stub was turned into a park and ride lot 20 or so years ago...

Did they close off the ramps or no? It looks like you can't access them anymore.

That interchange was never opened to public travel, only to Milwaukee County transit buses.  It has been cut back since.
