Strange Interchanges

[DJStephens]

Here's an interchange I've been through hundreds of times, but I could never draw it for you. I couldn't draw it two seconds after carefully examining the map. It's the connection between I-95 and US-1 in Lynnfield, MA.

Likely built that way, due to "packing in" of the area around US -1 and Route 128.   Appears to be an old style turnpike style of interchange, offset from the crossing itself.  128 was first envisioned in the 1920's and built as a four lane divided in late  forties / early fifties.  It was largely rebuilt in the very early sixties as a mostly eight lane between US -1 on the south and north ends.
   Two pieces, that should have been opened up to a 4 x 4 cross-section, then in the early sixties, inexplicably weren't.   Rte 24 to Rte 9, and also between I-93 up to US 1.  The southwestern quadrant was finally opened up to 4 x 4 in more recent times.   The older "original" four lane 128 section was very apparent E of Lynnfield/Peabody heading towards Gloucester.   
   95 "ended" for close to twenty years, N of 128, where it was directly E of US - 1, before a T directional connection was built with 128.   For quite a long time, it certainly appeared that it would never be connected properly with 128.

This whole Tonnelle Circle complex is something else...

This is like when I build an intersection in Cities Skylines and it becomes congested so I start making modifications and adding ramps and flyovers but it just keeps jamming up so I keep adding more ramps and flyovers and it becomes an indecipherable monstrous spaghetti mess.

Outside St. Paul, the interchanges on Rice Street with I-694 in Shoreview and TH 36 in Little Canada where standard diamonds were rebuilt with all ramps intersecting on the north side.

I just dropped by to say, it feels like a missed opportunity that this thread wasn't titled as I've done here.

Interstranges

Yes, that one…but did you un-edit my subject line so as to take the credit for yourself?

No, I just guessed! I'd say great minds think alike, but you don't want one as forgetful as mine.

If I quote something, it seems to automatically retains the thread title's subject line. I avoid modifying the subject title unless it's the OP (I used to remove the redundant "Re:" but the mods said that messed things up).

But I modified it here just because I forgot one can do that.

Earlier in this thread, someone mentioned I-205 in Portland, OR where it runs alongside I-84, which is cool. Just up the road in Vancouver, WA is this lovely interchange with WA-14:

14 runs along the edge of a plateau, so there's no place to put ramps south of the road. They squeezed a C-D lane in, too. There's also a bike lane up the middle of I-205, which disappears down a ramp and comes out right next to 14 (and which has Street View imagery).

Probably the most complicated interchange I've encountered is in Boston between I-90 and I-93, at the south end of the Big Dig.

It's especially gnarly on a map, where you can see the subterranean stuff too.

It's actually better than the old pre-Big Dig interchange, although more complex.

Found this interesting cloverleaf variant in Brazil between Rio and São Paulo:

Looks like it solves the majority of the weaving problems that normal cloverleafs have.

Apologies if this one has been brought up before in this thread, but to me, the epitome of 'strange' interchanges has to be the Golden Glades Interchange in the Miami, FL area.  To me, it is _the_ one that should be scraped off are restarted from scratch before all others.

South Florida's interchanges are quite literally built different in terms of how convoluted they can get. Here's the....interesting junction of I-595, Florida's Turnpike, and US 441. Oh, and Marina Mile Boulevard and I-595's express lanes for good measure: https://goo.gl/maps/s6kwtSThGmxMpGrXA

Google Maps calls that "Hacienda Village". According to Wikipedia, this village was entirely wiped out by the construction of I-595. It was known for funding its entire budget off traffic tickets, due to obscure speed limit postings. Looks like they finally got their comeuppance.

Wow, this place almost makes Waldo or Lawtey's speed traps look reasonable.

I-69 at Coldwater Road in Fort Wayne, IN. Loop ramps, left merges, and an usual connector road for a side street in the median next to an old cemetery.

In case you didn't know, when this complex junction was built in the mid-1960s, Coldwater Road still carried U.S. Highway 27. The presence of the cemetery and then high-volume of traffic on Coldwater both complicated the design of that interchange by preventing construction of the typical (for the time) cloverleaf. US 27 was later rerouted to take Lima Road north from Clinton Street to I-69, where it then joined the Interstate on a multiplex all the way to Michigan. It was subsequently truncated nationally, and the Lima Road (Indiana S.R. 3) interchange (original Exit 111 on I-69, now 311) became the northern terminus for US 27 (as well as the southern terminus of the northern section of IN 3, which used to go all the way through the Summit City).
