Title: Freeway segments of fully decommissioned US routes (in particular, US 66)
Post by: TheStranger on May 13, 2021, 02:35:11 PM
A thread idea that's been around in my head for a long time but finally came back to me just now:

California roadgeeks are familiar with the Arroyo Seco Parkway (Pasadena Freeway) originally being built as US 66, which stands out in comparison to how much of the focus of Route 66 has been on ancient conventional roads of various types (undivided two-lane, four-lane both divided and undivided).  So it got me thinking, what segments of existing freeway have been part of US 66?  In California I can think of several (US 101 in Hollywood/Echo Park, all of the Arroyo Seco Parkway, a portion of the Colorado Freeway/Ventura Freeway that was Alternate US 66 near Eagle Rock, and portions of I-215, I-15, and I-40). 

Then this got me thinking: This could also apply to US 466 too!  (part of US 101 near Atascadero, parts of Route 99 and Route 204 near Bakersfield, and just about all of I-15 going towards Nevada)

The old Maryland/West Virginia US 48 fits this easily (as it was entirely supplanted by I-68).  And US 99 is an easy one as existing I-10, I-5, US 101, much of California State Route 99, Route 204, Business I-80/Route 51 (as US 99E), Route 275 and US 50 (as US 99W), I-80, Route 65, Route 70, and portions of Washington State Route 99 all have operated as US 99 at some point.

In order for a road to qualify for this thread, it has to have been signed as the US route in question - simply being planned as such, but never signed for it or never built, doesn't qualify (so US 6 being the proposed designation for the Route 170 portion of the Hollywood Freeway doesn't qualify in addition to the fact US 6 is still around much further north). 

Curious of other examples that I haven't thought of.

For US 66 in IL, it was already a divided 4 lane between St Louis and Chicago before the interstate era. When I-55 was being constructed, for the most part, one direction of US 66 was upgraded to become one direction of the lanes for I-55, while the other direction became a 2-way frontage road, and the other I-55 lanes was constructed from scratch. So for the purpose of this thread, half of the I-55 lanes was part of pre-interstate era US 66.

There is a portion of I-96 west of Grand Rapids where the freeway was built on top of former US-16.

There is also a bit of I-75 built on top of what was then US-27 near Grayling.

The Alaskan Way Viaduct absolutely fit this thread, not sure if any of the other WA 99 freeway segments were built as US 99.

SR 99 generally follows the post-1953 (but pre-1960s) alignment of US 99 before it was shifted over to completed sections of I-5.

SR 529 also follows an expressway-like section of US 99 that opened in 1954, with the twinning of the Snohomish River bridges and a bypass of Marysville.

Washington started upgrading sections of US 99 to limited-access standards in 1947, including building new bypasses and alignments used today by I-5. Besides the viaduct and its associated freeway to Tukwila (which was upgraded to a freeway prior to US 99 being fully decommissioned), these sections of upgraded US 99 are now part of I-5:

Salmon Creek (I-205) to Woodland (SR 503)
Woodland (Dike Access Road) to Kelso (SR 432)
Castle Rock to Chehalis
Grand Mound to Tumwater
Lacey to Lakewood (Ponders Corner)
Marysville (SR 529) to Stimson Crossing (136th Street)
Conway (SR 534) to Burlington (SR 11)

(This was off the top of my head, so some bits might be a bit off)

Wasn’t 599 also a US 99 freeway alignment or was it expressway grade at the time?

It's before my time, but I vaguely recall that parts of US-21 in Ohio were freeway segments before I-77 was signed.  Perhaps the concurrency in northern Summit County was one of these sections.

US-65 was decommissioned north of Albert Lea, MN... but I think parts of current I-35/35W (and the MN-65 freeway stub, and MN-121) north of that were designated US-65 at one time.

A lot of the I-83 freeway in PA is former US 111 (and it shows)

I believe I-283 and the section of I-83 between I-283 and I-81 was Bypass US 230

There wasn't that much built as US 111 in MD in looking at the 1957 aerial view.  There was the six mile stretch from the Baltimore Beltway to exit 20.  North of there it was built as a super-2 up until north of Hereford.  But exit 24 for Belfast Road only had a partial interchange which included an intersection on US 111.  Though there was some construction on the PA side of the state line.  Unfortunately that aerial view doesn't go far into PA. 

In PA there's a 1958 topo map that shows the northern part done from about Carlisle Road down to PA 297 and under construction for a bit south of there to the end of the map.  AFAICT that would be the only section that seems likely to have been signed as just US 111 freeway.  The parts that open later may have already been signed as I-83.  The 1957 York County map shows the whole route as I-83.  But who knows what's actually completed at the time and what it was signed as. So it's hard to say. 

As for US 230 bypass, the 1958 topo shows it goes from US 22 to PA/US 230.  But it looks like a two lane non-freeway bypass.  I think that was actually what is now Eisenhower Blvd.  So it doesn't fit what's being looked for in this thread.

Everything that was built was signed as an Interstate from the get-go, so US 65 doesn't qualify (nevermind that US 65 still exists in Minnesota...the OP's criteria disqualify it).

There was also a US-48 in California at one point

Indiana had only two US roues that have been fully decommissioned: US 112 and US 152, both of which went away before freeways were even a thing.

US 460 may have had freeway sections in Evansville before going away in Indiana, but it still exists in other states.

Not sure any of the freeway lanes use pavement/roadway that was ever US 48 though.

Along those routes:

- Castro Valley Boulevard and Business I-205 each represent former US 50/US 48, while 580 and 205 use a parallel alignment

- Even if the 262 upgrade to freeway happens, that would have never been signed as US 48 at any time in its history.

Yes, but that was all at-grade divided highway with the exception of the following:

The current I-55 freeway from Gardner to Welco Corners (I-355 today).  This was completed in 1956 as a pre-interstate freeway for US-66 as a bypass of both Joliet and Plainfield.

North of Sacramento, the present route of CA 99 (the portion not "coincident" with I-5 north of Sacramento) between downtown Sacramento and Yuba City was at one point SSR 24 (LRN 232), an unsigned section northwest of Nicolaus (LRN 245), and old Alternate US 40 (LRN 87), into Yuba City from the south.  North of Yuba City, it was US 99E (LRN 3), but with a coincidence with SSR 36 (LRN 29) for the last three or so miles into Red Bluff, where it rejoined US 99W and continued on north as basic US 99 (and the continuation of LRN 3).  Currently, CA 99 terminates at CA 36 east of Red Bluff along the old US 99E alignment.

Wasn’t the section from 355 (obviously wasn’t there when initially built) to 294 also built to a Freeway before the I-55 designation? Hence why Joliet Road/Old US 66 is multiplexed on this section?

IIRC, during that era:

US 99E: along today's Business 80/Route 51
Route 99: along Broadway and 3rd/5th Streets, since bypassed as the sometimes-signed-as-99 WX Freeway and sometimes-signed-as-99 I-5 "boat" segment.  Also used Jibboom Street, Garden Highway and the southernmost portion of El Centro Boulevard.  All of this surface routing was 1957-1964 Route 24.
US 99W: N Street, Capitol Mall/(Route 275), US 50 (on what had been US 40/US 99W/I-80).  I THINK there was a time where the 99W/99E split was the Broadway interchange along today's Route 99, based on one of the old signs in the AARoads shield gallery.  Prior to the construction of the 29/30 segment of today's Business 80, the 99W/99E split had been around N and 15th.

State Route 99 wasn't removed from the surface streets until the completion of the WX Freeway if I am not mistaken, so around 1969-1970.

To top it off CA 70 was co-signed with CA 99.  All this can be seen on the 1966 DOH map:

http://www.davidrumsey.com/ll/thumbnailView.html?startUrl=%2F%2Fwww.davidrumsey.com%2Fluna%2Fservlet%2Fas%2Fsearch%3Fos%3D0%26lc%3DRUMSEY~8~1%26q%3DCALTRANs%201966%26sort%3DPub_List_No_InitialSort%2CPub_Date%2CPub_List_No%2CSeries_No%26bs%3D10#?c=0&m=0&s=0&cv=0&r=0&xywh=6348%2C663%2C941%2C1541

It’s worth noting though that the AASHO approved punting US 99 out of California during June 1965.  Probably took several years for the signs to be replaced.

The Tri-State Tollway in IL was Toll US 41 in its entirety, and the Southern portion of it was also Toll US 30

The East-West/Reagan Tollway (to its original western terminus in Sugar Grove) was also Toll US 30

Bonus points, that currently unnumbered 4-lane divided freeway/tollway “ramp” between the south-facing Tri-State and west-facing Reagan was originally numbered Toll US 30

The Toll bannered routes were decommissioned long ago

Wasn’t 599 also a US 99 freeway alignment or was it expressway grade at the time?

SR 599 was never part of the actual US 99, but was signed as US 99T/SR 99T (for Temporary) for a bit.

Indiana had only two US roues that have been fully decommissioned: US 112 and US 152, both of which went away before freeways were even a thing.

US 460 may have had freeway sections in Evansville before going away in Indiana, but it still exists in other states.

Before being Decommissioned,  Wasn't US-112 on part of what is now I-94 near Ann Arbor (the Willow Run Expressway system)?

The point being made was that US-112 was removed from Indiana; it had previously ended in Elkhart and later Rolling Prairie.  It was extended over the current route of US-12 in the 1930's, before freeways.

I was only commenting from the standpoint of Indiana. I don't really know where US 112 went in Michigan, but in Indiana it wasn't on any freeways.

US-112 in Michigan is todays US-12. the Original US-12 in Michigan ran along I-94 between the Indiana line and its Eastern end in Detroit. When US-112 was decommissioned in 62, US-12 replaced US-112. There is some roads near US-12 that have the street name Old US-112.

US-12 also use to take a different route into Detroit. It went basically along today's M-14 to Plymouth Road and came into Detroit on Plymouth then turning at Old US-16 aka Grand River to go downtown. For awhile it ended at Plymouth and Grand River.

At this time US-112 used Michigan and when US-12's route was switched it came in on Michigan like it does today. It ends at Michigan and Cass but use to extend to Cadillac Square.
