Clusterfucked interchanges

[vdeane]

Maybe he meant the Canton interchange?

The worst I can think of in Michigan is the I-96/I-196/M-21/M-37/M-44 interchange system.
Dishonorable mention to I-96/US-31/BUS US-31 and I-96/US-23 (which likely was the worst prior to MDOT bridging I-96 over the whole thing to eliminate left entrances onto mainline I-96)

[silverback1065]

It's not there anymore, but the Peabody interchange between I-95 and 128 used to make me carsick.

I presume you mean when you had to use US 1 between Lynnfield and Danvers to get from I-95 to 128, before there was a direct interchange between the two roads.

No, ment between I-95 and 95.

I think you need to elaborate regarding "not there anymore" (your words).  Both the direct-connection between I-95 & MA 128 (opened circa 1988) and the once-temporary/now permanent, partial-movement I-95/US 1 connection in Peabody built circa 1974 that Roadman referred to are still there.

If you were referring to the I-95 (MA 128)/US 1 interchange built circa 1962 at the Peabody/Lynnfield line; that one's still there as well.

Maybe I'm just stupid, but I clearly remember a big loop to stay on 95 north that is now gone.

There is a 120° change in direction, but a large angle by itself doesn't mean anything in terms of traffic.

Eh, I'm not sure I agree with that, the curve itself can cause traffic to slow down, which can cause a backup.  lane drops also tend to happen at these jogs too which makes it worse

[roadman]

Maybe he meant the Canton interchange?

That would make more sense.  On the north end of the I-95/128 overlap, the only 'big loop' within the Lynnfield interchange complex to get onto I-95 is going from Goodwin Circle/MA 129 to I-95(128) south.  That ramp was put in after I-95 was re-routed onto 128 in early 1975, whereas the "suicide ramp" from I-95 north to I-95 (128) north in Canton has been in place since the highway was built in the 1960s.

Given that he lives in Needham; one would hope he would at least know which towns are north & south of Boston.  Saying Dedham or Randolph instead of Canton is forgivable IMHO; but Peabody, come on.

And again, he stated that the interchange is not there anymore.  Regardless of which interchange he's referring to; no interchange along the entire stretch of I-95/MA 128 between Canton & Peabody has been eliminated.

well my brain is apparently messed up or something. Maybe the Peabody interchange is still there

[vdeane]

I'm guessing you may have misremembered Canton as Peabody and then assumed it was removed when you couldn't find it.  Or misjudged the geometry (I know I did that once or twice when I was younger).

[PHLBOS]

With all due respect, are you even reading any of the inserted posts... particularly the one containing Google Map links showing all 3 Peabody area interchanges (reposted below):

Both the direct-connection between I-95 & MA 128 (opened circa 1988) and the once-temporary/now permanent, partial-movement I-95/US 1 connection in Peabody built circa 1974 that Roadman referred to are still there.

If you were referring to the I-95 (MA 128)/US 1 interchange built circa 1962 at the Peabody/Lynnfield line; that one's still there as well.

Click on any one of those links ('hot' links appear as different-colored text) and you will plainly see that they're all still there and haven't changed in decades.  The same holds true for the Canton interchange (regarding no change in ramp geometry in decades).

The 610 West Loop/ I-69/US59 Southwest Freeway interchange.
https://www.google.com/maps/@29.7298623,-95.4569902,16.29z

It's an early 4-level stack completed in 1962. It was Houston's first stack interchange that's remained relatively unchanged over the last 55 years save a few modifications. Since it originally opened, it's become one of the state's largest bottlenecks, complicated by the fact that it's in close proximity to the Galleria and Uptown, the nearby terminus of the Westpark Tollway, sharp ramps with not enough capacity, and weaving issues caused by exit and entrance ramps to and from nearby Chimney Rock Blvd. on 69/59.

There's a fix coming soon. Over the next few years, the interchange will be rebuilt to eliminate many of the problems. Construction is slated to start later this year and wrap up in 2021.

Not even half as bad as 45/59/288. I've seen VMS predictions of 90 minutes to get through that beast.

I-35/I-435/K-10: https://www.google.com/maps/@38.9434001,-94.7593641,15.21z?hl=en

Before the Johnson County Gateway Project, I-435 had separate interchanges with K-10 (Exit 1B) and I-35 (Exit 83), with an interchange for Lackman Rd. (Exit 1A) in between. Now the K-10 and I-35 interchanges are linked together with a bunch of new ramps and C/D roads, and Lackman almost seems to have been lost. Heading SB/EB on 435, the exit for I-35 comes just after the exit for K-10. Due to a lack of signage for Lackman, most people would not notice that Exit 1A no longer exists in that direction, and that you have to follow signs for I-35 to get to Lackman Rd.

There is still one more phase to the project that will just add to the mess. Here's what it will look like when it's complete: http://jocogateway.com/wp-content/uploads/2014/04/2014-04-10-Ultimate-Exhibit_sized.pdf

The I-435/US-69 interchange just to the east is almost close enough that it could be lumped in with all of this too.

The Preston Hwy/I-65/I-264/Freedom Way/Terminal Dr/Crittenden Dr interchange.

https://www.google.com/maps/@38.1852311,-85.7370921,14z/data=!3m1!1e3



It originally was two cloverleafs directly next to each other with Preston Hwy and Crittenden Dr being isolated. The interchange was upgraded in the late 80s or early 90s. A challenge with upgrading the interchange was having Louisville International Airport directly south, so they had to make all roads at or below runway level.

The I-70 / I-270 / Quebec Street (CO Hwy 35) / Northfield Boulevard / Smith Road cluster in northeast Denver is a mess.

https://goo.gl/maps/Gi97cEnC5jP2

I-70 has a full interchange with Quebec Street and I-270 has a partial interchange with Quebec Street.....while Quebec Street has a full interchange with Northfield Boulevard and an exit ramp set-up with Smith Road. Quebec Street is a winding road, lanes get dropped, lanes are either excessively wide or too narrow at different points, merge points are always choked, etc.  It's a perplexing area to drive through. Take a look on StreetView if you have a minute.

In general I-70 and I-270 and their interchanges are a general mess east of I-25. Each interchange affects the other thanks to outdated infrastructure and unprecedented volumes of traffic. That should hopefully be remedied in the years to come with the Central 70 project: https://www.codot.gov/projects/i70east

I have lived here for just under 3 years and have noticed quite a bit of gridlock and bottleneck. Talking to Colorado natives, it seems like things have gotten really congested over the last 10 to 15 years.

That's not a cluster****ed interchange; that's a cleaned-up interchange.

It has to be all the new people moving there, it's a great city, I'd love to live there.

Death Valley in Greensboro, NC is the merge point of I-40, I-85 Business, US 29/70 and US 220. There are left and right exits/entrances within half-mile of each other. I-40 and Business 85 merge so close to the Randleman Rd exit that 2 separate ramp sets are required. For about a mile, the road is signed as:
I-40, I-85 Business, US 29/70/220 (and US 421 used to be routed along here too).

https://www.google.com/maps/@36.0309201,-79.8052442,15z

I agree.. This one.. is a pain. I often use The Southern Loop to avoid this part.

Eventually that part of the road will be fixed, starting with the widening of the Buffalo creek bridge between Randleman and Elm-Eugene St interchanges in 2019. They are currently working on the widening of the bridges that carry I-40 West as well as the ramp to MLK Jr. Dr. over US 29. Then, after the Beltway is completed, they plan on fix that dangerous section.. although I don't know when it will happen.
