Last original Interstate built?

[Bickendan]

Funny thing is, I moved from the LA area to Medford Oregon in '89, and there was at least one, two trips back down before '93 and I don't remember any incomplete portions of I-5.

There were some RIROs but no major intersections.

Last Interstate built... that's easy, US 39.   

Unless you're being sarcastic, but that isn't an interstate.

It is a U.S. Route, however, to continue the unfunny sarcasm.

No, it isn't.

You're right. It's funny as hell.

What is a RIRO?

^People still cheat and turn left there since there's no real barriers. I almost hit someone that was doing it a month or so ago.

Uh, yeah, there's a barrier there, if you count a series of red poles.  There are also U-turns just east and west, not for public use.  Were people trying to make Michigan lefts?

I saw people making both Michigan lefts and driving wrong-way on the opposite carriageway for a short distance when I lived in the area. Street View shows the tire tracks clearly.

I-95 is not complete to date.  I remember that there was a significant porition not complete in Florida in the late eighties.

Yeah, I-95 through Jersey

Why is that?  I answered the question asked.  I do recall that segment on I-90 through Wallace as well.  My parents were ticked about being dumped off the interstate and I was thirlled to get off the interstate.

1991 Rand McNally still shows the following incomplete:
*I-90 Wallace: September 1991
*I-70 Glenwood Springs (1957 addition): October 1992
*I-476 Philadelphia: December 1992
*I-287 Boonton-Suffern: November 1993
*I-295 Trenton: December 1994

So (unless Rand McNally was crappier than usual) I-90 was in fact the last original two-digit. I-70 was the last 1950s two-digit, and I-295 was the last period.

Rand McNally is missing I-90 in Seattle - it was still incomplete to I-5 until 1992, per the temp I-90 BGS in Seattle.

Why is that?  I answered the question asked.

What was the last Interstate from the original Yellow Book plan to be built? (Note: major realignments such as I-95 around Trenton don't count; everything that will be built has been built.)

I don't see why one wrong post should be deleted.  If the thread contains an error, the only reasonable thing to do is delete the thread and ideally the rest of the subforum, too.  Otherwise how will we truly cleanse of the Wrong?

When was I-5 north of Lake Shasta to Oregon completed? Late 80s?
I remember seeing maps showing a non-interstate segment.

My recollection is late 80s.  I was making a 2-3 trips a year from Seattle to S.F. then.  But prior to that, it was near-standard:  4 lanes, 12', shoulders, 55 to 60 mph speed limits, just one place where left turns were allowed.  I'm sure there are places that are farther below standard than that in the original interstates that are left. (I-80 S.F., cough cough.)

In Seattle until 1992 you had to get completely off the I-90 freeway onto city streets.

Yeah, I can't find an exact date for this, but I'm pretty certain I-90 in Seattle was 1992, while Wallace was September 1991.  Kind of funny that Wallace tries to claim the last section of interstate completed when it wasn't even the last section of I-90 in a two-state radius.

I can see a couple of ways that "last traffic light" would still be true for Wallace on I-90 on a technicality (i.e. the Seattle routing had a TEMP banner, so traffic lights in Sodo weren't technically on I-90), but given that traffic lights still exist on interstates today, it's obviously not the last anywhere.

Nowhere close. I-70 and I-78 have lights. Heck, depending on your interpretation, I-90 has a light at its WT and NYSTA uses standard signals at its toll booths. Thus, one must pass six lights in New York alone if you want to be literal.

I think what the mean with Wallace was I-90 was designed to exit onto city streets and then restart the freeway on the other end of town. The problem was the tight valley trying to fit in a freeway without destroying a mountain or destroying the town. The other gaps were 'temporary' in design. Not much different than I-70 at Breezwood having "TO" trailblazers to handle traffic. Though the idea of a direct connection has been completely shot down (similar to I-95 north of Trenton, it may have been planned, but it will never happen now).

[Kacie Jane]

Right, but it was exactly the same with I-90 in Seattle.  You went through the last interchange at Rainier Avenue, and then were funneled onto city streets (the old US 10 alignment, just like Wallace) to continue to I-5.  The problem was the hillside and trying to fit in a freeway without destroying the residential neighborhoods.

The gap in Wallace was just as "temporary". They knew I-90 wasn't going to be on the city streets forever; it was just a question of whether they'd build the freeway at-grade through town or on a viaduct on the north side.

[CtrlAltDel]

What was the proposed routing of I-90 through Wallace, ID, anyway?

[Bickendan]

Does I-90 still have a super-4 like segment in Montana?

The original plan would have required taking about 40% of the town's downtown area.

Looks like there was some serious Evel Knievel rampage at I-5 prior to the road being finished!

Nope. The segment in question, near the Idaho line, has a jersey barrier now:
https://www.google.com/maps/@47.45101,-115.693849,3a,49.9y,176.99h,76.87t/data=!3m4!1e1!3m2!1senvJsUYMMt6bDBp4RvoCAg!2e0

My understanding is that this barrier dates back to the early 2000s, basically not long after the IHOZ site (which had documented this irregularity) last updated.
