Freeways that were formerly signed Interstates but now are not in the system?

Wikipedia claims the existing segment of NC 147 in Durham, North Carolina was originally built as I-40, but has no sources for it.  Anyone know if this is the case?

According to http://www.gribblenation.com/ncpics/history/i40.html the routing on NC 147 was approved in 1968, but in the 1970s the alignment was changed.

US 131 In Grand Rapids used to be signed as I 296 back in the the 70's however I'm not sure if it still part of the Interstate system.

[pianocello]

I'm pretty sure I-296 is still part of the system, only unsigned. I never thought it was signed at all, but I must be mistaken.

Nassau Expressway signs at Cross Bay Blvd In  On Ramp was signed as I-78 when opened in the early 1970's then resigned as I-878 then resigned as NY 878. (NYSDOT reference markers show 878I)

This is still in the system as I-878.

Hey, does anyone know if the former US 395 freeway in San Diego - not Route 163, but Kearny Villa Road through MCAS Miramar between Miramar Road and Route 163 - was ever signed as I-15?

http://maps.google.com/maps?q=Kearny+Villa+Rd+%26+Miramar+Rd,+San+Diego,+CA&hl=en&ll=32.871874,-117.118549&spn=0.04938,0.104628&sll=32.874037,-117.120609&sspn=0.02469,0.052314&vpsrc=6&hnear=Kearny+Villa+Rd+%26+Miramar+Rd,+San+Diego,+California+92126&t=h&z=14

This would absolutely count if so.

It almost certainly was signed as I-15, when I lived in the area and before I-15 was re-routed to the east.  I recall it had regular I-15 signage, while Murphy Canyon Road down to I-8 was just "temporary I-15" (that road was upgraded tp freeway on more or less its old alignment, before getting regular I-15 markers).

I have my doubts that I-95 was signed on the Harbor Thruway, since from the get-go, the planning was for I-95 to go through downtown along a different routing.  This is one of those cases where I'd want a photo as proof otherwise.

It wasn't an interstate when it was built, but what is up with the short freeway section of PA 309 in Allentown between I-78 and US 22? Where it's located and how it's built (narrow freeway with a narrow Jersey barrier median) looks like it was once an alignment of the Northeast Extension.
http://maps.google.com/maps?q=allentown,+pa&hl=en&ll=40.594403,-75.553064&spn=0.038388,0.077162&sll=40.638967,-75.146484&sspn=1.169204,2.469177&vpsrc=6&hnear=Allentown,+Lehigh,+Pennsylvania&t=h&z=14

I don't think it was because the section that is now co-signed with I-78 was that way as well before it was rebuilt to handle I-78.

It's always struck me as simply another narrow Pennsylvania freeway.

Wikipedia claims the existing segment of NC 147 in Durham, North Carolina was originally built as I-40, but has no sources for it.  Anyone know if this is the case?

Thanks for the link!  So it may have never been signed as I-40 but was proposed as such and approved as part of the system.

 Interestingly, the "East End Connector" from NC 147 to US 70 that is slated for construction soon, and the half-freeway/half-expressway US 70 from I-40 to I-95 in Smithfield all seem to have been submitted as well...they probably fit in with TN 840, the 470 beltway in Denver, VA 895 as roads built/to be built as non-Interstates but originally created with the intention of being designated as Interstates.

The freeway that is now NC 147 was shown as a dotted line on the 1962 Durham County map, running from US 70 Bus Hillendale Blvd just west of Erwin southeast through Durham to about Briggs Rd, then cut east (now East end Conn) to end at US 70 near the east end of US 70 Bus.

The 1968 Durham County map shows a second dotted line along today's 147 south of the east end connector down to a dotted line in the general location of I-40, whose dotted line west stops at the NC 54-751 jct area.

No route designations are given to any of the above dotted lines.

The 1972 Durham County Map http://dc.lib.unc.edu/cdm4/document.php?CISOROOT=/ncmaps&CISOPTR=8413&REC=9shows the 147 dotted line's northern end moved to the current NC 147 location where it ties into I-85.  I-40 is labeled on a completed road running from what had been historically the south end of NC 147.  The I-40 dotted line continues west (more southerly route than 1968) to the Orange County Line.  From the 147-40 jct north to past US 15-501 business the map shows a road "under construction" but does not label it as any route number.

The 1980 Durham County Map shows the same except the I-40 dotted line west of 147 curls more northwest as it does now.


No official NC map shows the 147 freeway as I-40

I drove it many times before I-95 opened, and it did not have a number, but it did have periodic "TO I-95" sign assemblies, the "TO" on a white sign placed over an Interstate shield sign.

It was signed, and marked on state maps through 1979. In fact, I have a copy of an article from December 1962 from The Grand Rapids Press showing the opening of I-296/US 131/M-37, complete with the three markers in a photo.

According to the Wikipedia article, the Thruway was signed as I-895 in 1979, six years before the entire length of I-95 through Maryland was completed!

I travelled that road, or else passed it en route to I-695 to avoid the Harbor Tunnel, many times in those years and I do not remember an I-895 designation appearing that early, because when the Fort McHenry Tunnel opened I remember quite a few people I know being surprised to learn that the Harbor Tunnel was not I-895. Had the I-895 signs been there for a longer time, it wouldn't have surprised anyone.

I note the Wikipedia article says it was "designated I-895 in 1979," citing to a Maryland road map from that year. I suppose there's potentially a difference between "designated" and "signed." I've noted various sources that say the number was applied in 1981 or 1983 or thereabouts and that it showed up on signs later. That's about what I recall as well.

For a brief period in the 1960s, the freeway section of what is now US 1 between the Tobin Bridge in Boston and Revere (aka the Northeast Expressway)was signed as I-95.

there was a surviving sign well into the 2000s.

Yes.  It was on the northbound Tobin Bridge, and read "TO 95 NORTH".

I don't recall any I-895 signing before the Fort McHenry Tunnel opened.  It was at least a couple years later.

Was the Wade Avenue Extension in Raleigh ever officially I-40?  Wikipedia notes it was signed as such until the segment connecting US 1/I-440 westward was constructed, and I recall seeing this on maps years ago.

[PAHighways]

PENNSYLVANIA
- I-378 was demoted to Route 378 (but was built as an Interstate) once I-78 was rerouted to bypass Allentown/Bethlehem to the south; concurrently, the US 22 Lehigh Valley Thruway had been I-78 until then.

The I-378 designation stuck around for a couple of years after the decision was made to build 78 as a southern bypass of the Allentown/Bethlehem/Easton area.

The short segment of PA 309 from US 22 to I-78 was never an alignment of the Turnpike's Northeast Extension. It was simply a four-lane freeway between US 22 and what is now I-78's Exit 60. From the location of that exit, PA 309 curved to the south as a two- and four-lane rural arterial.

The segment from what is now Exit 53 to Exit 60 was widened and incorporated into I-78 when that interstate was built.

What was the reason for removing the I-296 signs? It seems like most of the hidden interstate designations never have had interstate signs.
