Longest ramps/interchanges?

[Buffaboy]

What are the longest ramps/interchanges you know of? If you zoom out of a city or area in Goggle Maps, some of these freeway connections look like stubs. The ones I post probably aren't that long:

I-189 in Burlington, VT.

I-189 in Burlington, VT. 

Hahahah, too funny  . Seriously though!

[roadman65]

I-75 and I-275 to FL 56 (Exit 275) in Hillsborough and Pasco Counties of Florida.  The ramp itself is 2 miles long.

[MikeTheActuary]

How long is the ramp from I-294 NB to I-88 WB?

[hotdogPi]

What about SR 641 in Indiana?

[Big John]

I-865 NW of Indianapolis? 

[wanderer2575]

I-96/I-275/I-696/M-5 interchange in Farmington Hills and Novi MI.  I can't recall the statistic but this thing takes up a lot of land.  The ramp from I-275 north (really I-96 west) to I-96 west is two miles long.  A couple other ramps are a mile or more long.

Right now, maybe. But once the entire highway is open it will have two exits before reaching its end.

Detroit has the population of Charlotte but has the road network of Chicago. It goes to show the impacts of the population decline might extend far out into the suburbs as the ramps seem a bit rough.

The ramp from I-435 South to I-470 East is pretty damn long. It's got to be over a mile altogether doing that movement. It's similarly long on that ramp if you're going from I-435 South to I-49 South.

[TXtoNJ]

The ramp from 290 East to I-10 East in Houston is ~ 3.3 miles long.

[BakoCondors]

Not a three-miler but pretty long nonetheless. 10 East to 17 North west of downtown Phoenix.

[SteveG1988]

I275 at 74 in Ohio has a super sized trumpet.

[jakeroot]

The HOV bypass ramp from the 5 freeway to the 55 freeway in Santa Ana (CA) is about 1.8 miles long. It's a treat for those going to/from John Wayne Airport/Disneyland.

[peterj920]

I-39 and US 10 West north of Stevens Point, WI.  The trumpet interchange was built larger than a usual trumpet so the inside loop could be signed at 45 mph.  It's the fastest I've seen a 270 degree ramp I've seen.

The toll ramps on I-35E to/from I-635 are pretty damned long as are those on the eastern side of the Hi-Five.

[jbnati27]

The ramp from KY18 to I-71/I-75 Southbound in Florence, KY is pretty long. I've been burned by that one before, LOL, because I wanted to take I-71/I-75 to US42/US127 and the ramp takes you all the way down past that exit.

[jbnati27]

Another couple examples I've thought of off the top of my head:

     - PA51 South (Sawmill Rd.) to I-376 West in the Pittsburgh area

     - The I-64 East / I-77 South split near Beckley WV

Well, part of it isn't population decline so much as better planning than Chicago or Charlotte.  Detroit's planners intentionally built a larger (meant to be even larger - missing parts of the Davison-Mound Freeway) road network from the start.  This includes the boulevards such as 8 Mile and Telegraph.  It actually functions better on a daily basis than Chicago's pretty shitty road network.

I feel certain I've done this exact thread sometime before, but for the life of me I can't dig it up right now.

(Actually, what I think I asked about was longest interchange only; i.e., the longest span along a main route from the first exit ramp to the last related entrance ramp. But it got a lot of replies about the longest single ramp, as well.)

[Jardine]

SW Omaha, I-80 westbound off ramp onto 144th is weirdly long.  IIRC, it was either something to do with how the interchange was rebuilt while keeping it open, or a car park for the slowly timed traffic light at 144th.  Mebbee both.

Did anyone bring up that bridge that's part of the Mixing Bowl (I-95/I-495/I-395)?  At least when I toured the site when it was being constructed, it was touted as one of the longest bridges in the country that did not cross water.

Exit 15x on the NJTP near Secaucus transfer is a very long ramp.

It may not have been brought up because technically the bridge you're referring to is not a ramp.  It's the I-95 mainline.
