Freeway segments of fully decommissioned US routes (in particular, US 66)

[Max Rockatansky]

wasn't ca 99 all us 99 at one point?  south of sacramento it's all interstate grade (some portions badly needing a third lane in both directions).

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.

It gets stranger given US 99, US 99E, US 99W and CA 99 all briefly existed at the same time in Sacramento.

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.

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)?

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

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. 

[US 89]

I believe US 30S was routed on some of the earlier completed portions of I-84 (then I-80N) in Utah before it was decommissioned in 1972.

[jp the roadgeek]

I-691/CT 66 east of I-691 Exit 4 is a portion of the decommissioned US 6A.

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.

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.
