What would you say is the most important or most heavily used interchange in your state for each interstate highway that runs through it? For this thread, I'm excluding interstate-to-interstate connections, such as I-77/85 in North Carolina. So list a state, list an interstate highway, and list your candidate for the busiest interchange.
SOUTH CAROLINA
I-20: Clemson Road (Exit 80) (The Broad River Road exit at MM65 is very close, but the proximity of other exits to that exit gives the edge to Exit 80.)
I-77: Strom Thurmond Blvd/Forest Drive/Fort Jackson (Exit 12)
I-26/95/85: (This is a tough one. I'll let someone else take a stab at this one.)
Tough call for Connecticut! Perhaps I'd go with
I-84: CT 8 in Waterbury (the so-called "mix master")
I-91: US 5/CT 15 in Hartford for the Charter Oak Bridge
I-95: CT 34 in New Haven or CT 8 in Bridgeport
Massachusetts:
84: US 20
90: Exit 18/20 (it's the same exit)
190: MA 2
290: MA 146
91: MA 57
291: US 20 (end of overlap)
391: MA 141, west of the river
93: US 1 (northern end of overlap)
95: US 3 north
195: MA 24
295: US 1
395: US 20
495: US 3 / Lowell Connector (single interchange, 5-way)
I can find ODOT traffic counts for the freeways as they *pass* interchanges (some surprised me) but I can't find data regarding how many vehicles actually are using those interchanges. For example, I-670 at 4th clocks in with 181,830 but how do you figure out how many take the exit? Look at the counts for the next exit down and take a guess?
This begs a question to the OP: are you referring to total traffic going through the interchange, or the level of traffic that enters/exits at the interchange?
Wisconsin:
Zoo Interchange is #1 most used. Presentation from 2009 reported 345,000 AADT. Once it is done being reconstructed it will be able to handle even more cars with even less congestion and improved safety.
The Marquette Interchange from the same time reported 285,000.
Not sure of the numbers for the Mitchell / Hale but I'm sure they're lower since they're only 3-way interchanges. Unsure about Madison area interchanges too.

Ahhh, I meant the latter--traffic that actually enters or exits at that interchange.
The only one I would know for New Jersey:
I-95 / New Jersey Turnpike: Exits 73/74 and the George Washington Bridge
These others are complete guesses:
I-287: Either Exit 21 (I-78) or Exit 41 (I-80). Alternatively, Exit 37 for NJ 24.
I-78: Exit 52 (GSP)
EDIT: Didn't read the question thoroughly enough. Still stand for NJ 24 on I-287.

I-287: Either Exit 21 (I-78) or Exit 41 (I-80). Alternatively, Exit 37 for NJ 24.
I-78: Exit 52 (GSP)
The OP said to exclude interstate-to-interstate interchanges.
With that said, I'd agree that I-287's busiest is likely Exit 37 for NJ 24. I'll also agree that I-78's is likely the GSP. I'm also going to guess that the GSP and their local acess ramps is I-80 and I-280's busiest interchanges, although I'm not certain of either.
For I-64 in VA, most likely Exit 263 for US-258 in Hampton.
I-264: Exit 17 for Independence Blvd (since ADT on 264 drops from 93000 to 75000 past here)
I-464: Exit 2 for US-13 (464 is mostly a through route, so this is a complete guess)
I-564: VA-406.
I-664: Either Exit 13 for US-13/58/460 or Exit 9 for US-17/VA-164.
Alabama:
I-10: Junction I-65 north to Montgomery and Birmingham -or- US 90/98, Daphne/Fairhope (Exit 35 A-B)
I-20/59: "Malfunction Junction" interchange with I-65, downtown Birmingham -or- US 82 (McFarland Boulevard), Tuscaloosa (Exit 73)
I-20 (separate from I-59): US 411, Leeds/Moody (Exit 144-A/B)
I-22: will eventually be I-65 north of downtown Birmingham
I-59 (separate from I-20): Chalkville Mountain Road (Exit 141), Trussville
I-65: "Malfunction Junction" -or- US 31 (Montgomery Highway/Columbiana Road/Lorna Road), Hoover/Vestavia Hills (Exit 252)
I-85: Junction I-65, south to Mobile, north to Birmingham -or- AL-271 (Taylor Road), Montgomery (Exit 9)
I-459: US 280, Mountain Brook/Vestavia Hills/Hoover (Exit 19)
What say ye, fellow Alabamians, concerning I-359, I-565 and I-759?
For Indiana, I will only mention the highways I've driven in full length, because there will be exits I could easily overlook on the partial runs.
For I-65, I'd give the nod to U.S. 30 (exit 253). At one time, it was listed in the Top 10 busiest interchanges in the U.S. It serves almost every major retailer, and the ramp gets clogged heavily during the holiday season, to the point it's easier to take the ramp beforehand (109th Ave. northbound, 61st Ave. southbound) and use surface streets to finish the rest.
For I-80/94, Ripley Street (Indiana 51, exit 15). This interchange funnels U.S. 6 away from the expressway, and is a truck stop haven. It also connects to the nearby Toll Road interchange, which has its share of traffic due to the fact I-80 traffic has to use it to stay on course.
For I-80/90, Indiana 933 and U.S. 31 Business (exit 77), made apparent during college football season with direct access to Notre Dame. The toll gate is even designed to handle massive football traffic, and volumes are high to the point where traffic is directed six miles further east to the Mishawaka exit (or to the St. Joseph Valley Parkway if heading west).
For I-10 in Arizona, I think The Stack (the western I-10/I-17 interchange) carries the most total traffic, however, in terms of peak density the Mini Stack (I-10/Loop 202/SR 51) holds the crown.
New York has a lot of freeways that aren't Interstates, so this isn't so hard.
I-87: Thruway Exit 16 (likely), with Northway Exits 6-7 being up there
I-90: Probably Thruway Exit 55 (US 219). If not, Exit 51 (NY 33) or 54 (NY 400)
I-787: Likely NY 7
I-684: either Saw Mill Pkwy or Hutchison River Parkway
I-278: Grand Central Parkway
I-84: Probably NY 17
I-990: North French Road
I-290: US 62
I-190: Exit 9/Peace Bridge
I-678: Grand Central/Jackie Robinson Pkwys
I-587: NY 32/28 :spin:
Florida: I'll start with ones I am most familiar with in Jacksonville and Orlando. I-4 would be Florida's Turnpike or SR 535 big exit for Disney resort hotels. I-10 would be US 17 in Jax or possibly US 27 in Tallahassee. I-295 would be SR 21(Blanding Blvd). I-795 will be the exit at US1 (Philips hwy) this is a no brainer it will be the only exit that is not an interstate. I-95 I would imagine would be golden glades in Miami-dade county. I-75 I would surmise in Tampa area

I-490: Exit 23, NY 441
I-590: Exit 2 (A-B), NY 31
As for I-87, I'm gonna guess it's actually either the Macombs Dam Bridge or University Heights Bridge interchanges. Cross-County Parkway is another definite possibility.
And for I-95 it must certainly be NY 9A/Henry Hudson Parkway.
For I-495, I wouldn't be surprised if it's the Northern State Parkway crossovers at Exit 42. :-)
^^ Most of those are Interstate-to-Interstate. They don't qualify.

Aren't you forgetting the Braintree Split (I-93 (US 1)/MA 3)?
In Florida I would have to say I-4's busiest is Exit 74A for Sand Lake Road. It serves many tourist areas, including the Dr. Phillips area of Orlando with its recent developmental sprawl and of course Universal Studios nearby.
In New Jersey on I-95 it would be Exit 11 in Woodbridge. Back when I lived there it was the NJ Turnpike's busiest interchange with the road system's largest (maybe second largest if Exit 16E/ 18E is larger) toll plaza. The fact is that for an exit plaza it was always with more lanes than even the mainline plazas at Exit 1 and 18W or many other state mainline plazas.
In New Jersey on I-78 it always was Exit 33 for Martinsville Road. At one point NJDOT had to widen the overpass because corporate development in the area increased traffic counts through the interchange.
My guesses in Louisiana:
I-10: Causeway Blvd (exit 228) in New Orleans
I-12: either US 61 (exit 2A or 2B) or LA 3002 at Denham Springs
I-20: US 71/ LA 1 (exit 19A) in Shreveport
I-49: LA 3132 (exit 201) in Shreveport
I-55: US 190 (exit 31) in Hammond
I-59: Don't know much about this strecth, maybe US 11 (exit 3)
BR and NO area 3di's I may be totally off:
I-110: LA 73 Government St? (exit 1A)
I-210: LA 385 Ryan St? (6A)
I-220: US 71/LA 1 (7a/7B) or LA 3105 Airline Dr (12)
I-310: LA 3127 (exit 10)
I-510: Almonaster Ave? (2C)
I-610: Elysian Fields Ave? (3)
I-910: exit 11 Tchoupitoulas or 11A Camp St

Cross-County Parkway has a good argument. Problem is that we don't have a count of how many people enter/exit there. Traffic Data Viewer has Exit 16 near 50K (really easy because they put a counter between the tolls and NY 32). CCP is probably near that if not over.
Agree with the Rochester ones and I-95. Based on volumes, I'd say the LIE's busiest is the crossover at 38 (~40K).
Some of my Virginia guesses:
I-95: Well, it's definitely in Northern Virginia. Probably one of the parkways (VA 286 or VA 294)
I-195: The south end, with VA 76 and VA 195 (still freeway to freeway)
I-295: US 1
I-395: Old Mixing Bowl
I-495: VA 7
I-85: Either US 460 or US 58, probably 460
I-66: insert Ethanman joke here
I-381: just kidding, it doesn't have any
I-77: One of the ones on its overlap with I-81. Either US 11 in Wytheville or US 52 east of it
I don't have enough knowledge/experience with I-81 to make an educated guess.
NJ: Interstate 76/295/Nj42 interchange. I think it counts as the main road there is NJ42 after the interchange.
For South Jersey:
I-76: US 130 (by default; the other exits are Interstate Highway related)
I-676: I'm going to say the 5A,5B interchange for MLK Blvd, access to US 30, Cooper Medical & the Camden Waterfront
I-295: Probably NJ 73; followed closely with NJ 70, NJ 42 and US 1.
I-195: Exit 16/16A in the summer (Six Flags); otherwise Interchange 34 (GSP); Interchange 5 (US 130)
I-95 (Trenton area): US 1 or NJ 29
Well, California probably has everyone beat. I-10 and I-5 at the same interchange - East Los Angeles Interchange.
For southeastern PA, the I-76/US 202/422 interchange complex in Valley Forge/King of Prussia.

Interstate to interstate interchanges don't count. The busiest service interchange, if I had to guess, would be somewhere on the 405 since that is the road with the most traffic.
I'll go with the ones I know (or at least have decent guesses at):
I-74 Iowa: 53rd Street. Tons of retailers near that interchange, and many people use it for their daily commutes as well.
I-74 Illinois: I would guess the interchange in East Peoria for the Bob Michel Bridge. Signed for downtown, also serves one of Peoria's big shopping areas.
I-80 Illinois: This is a tough one. My guess would be US-45 in Mokena.
I-280 Illinois: IL-92/Centennial Expressway.
I-280 Iowa: US-61/River Dr
I-380 Iowa: Probably IA-100/Collins Rd NE

I-10...the interchange with I-95 definitely qualifies with the I-10/I-295 interchange a real close second.

I would guess a higher volume uses the CT 15/Charter Oak Bridge exit. That exit handles a very significant amount of the auto traffic between Boston and New York. (I wouldn't argue with your choice of the same for I-91, though the Wilbur Cross Parkway exit would be up there.)
MISSISSIPPI
I-10: US 49 (34 A&B), Gulfport
I-20: US 49 (47 A&B), Pearl
I-22: No idea
I-55: Lakeland Drive (98), Jackson or County Line Road (103), Jackson-Ridgeland border
I-59: US 49 (67 A&B) or US 98 (65), Hattiesburg
For Michigan:
I-75: M-102 (8 mile) or Bridge to Canada (Exit 47)
I-94: Metro Airport (Detroit)
I-96: I-96/I-275/I-696/M-5 or I-96/M-39
I-275: I-275/I-96/M-14
I-696: I-696/M-10/US-24
Quote from: Thing342For I-64 in VA, most likely Exit 263 for US-258 in Hampton.
Stronger arguments could be made for either VA 143/Exit 255 or US 13/Northampton Blvd.
QuoteI-564: VA-406.
The Gate 3 interchange. From years of personal experience.

He was.
Quote from: bassoon1986I-59: Don't know much about this strecth, maybe US 11 (exit 3)
Yep. Pretty much the only interchange on 59 that isn't a frontage road or doesn't dead-end.
Quote from: TakumiI-95: Well, it's definitely in Northern Virginia. Probably one of the parkways (VA 286 or VA 294)

If you're referring to near the Pentagon, then yes. More specifically, the ramps to/from VA 27.
QuoteI-495: VA 7
I'd think DTR would be more volumnous.
QuoteI-66: insert Ethanman joke here
Indeed. Though in reality, I think arguments could be made for each of VA 28, Fairfax County Pkwy, and US 50/Fair Oaks.
QuoteI don't have enough knowledge/experience with I-81 to make an educated guess.
I'd think it'd be a toss-up between US 11/460/Christiansburg, US 220 north of Roanoke, or US 33/Harrisonburg.
Quote from: brownpelicanI-22: No idea
Probably at US 45 in Tupelo.
QuoteI-59: US 49 (67 A&B) or US 98 (65), Hattiesburg
The former. Even MS 43 North/Exit 6 has more traffic than the latter. Though other strong possibilities exist in one of the Meridian interchanges (whether US 11/MS 19, MS 145, or MS 19/39).
--------
Since HighwayMap394 didn't catch the no-Interstate-to-Interstate note, here's my stab at Minnesota's:
I-35: likely at CSAH 5/50 in Lakeville.
I-35E: either CSAH 31/Pilot Knob Rd or Ramsey CSAH 96
I-35W: easily MN 62 (arguably the busiest interchange in the entire state).
I-90: this one's tough, as I-90 is lightly traveled compared to the other Minnesota interstates. I'd guess the eastern US 14/61 interchange next to the Mississippi River, as a lot of the traffic at US 52 or at US 63 is through traffic on the respective US route.
I-94: likely the US 169 interchange, though MN 280 would be a contender.
I-394: likely MN 100.
I-494: Several high-volume interchanges along I-494. If I were to pick one, it'd be the MN 5 East interchange near the airport.
I-535: technically, I wouldn't count this route, as there's only one interchange that isn't at another Interstate
I-694: US 10/MN 51 by far (specifically the US 10 part).
For Vermont, I don't count I-93 or I-189 as (like I-535 MN) they only have one non-Interstate interchange each. I-89 is easy, as the US 2/Exit 14 interchange is the busiest in the state. I-91 is fairly lightly traveled (especially compared to I-89). Based on experience, it would likely be one of the following: VT 9/Bennington, US 5/White River Jct, or US 5/VT 10A/Norwich.

Actually I am looking not so much as overall traffic counts, but as traffic that backs up onto the highway. Exit 74A Eastbound does that as both Kirkman and the Florida Turnpike have high speed connectors even though they may have higher numbers.
Exit 74A does that on random moments as tourists mostly use this exit and it all depends on what business is in town or what demographics are as many people from a certain region vacation all at the same moments, etc. Sometimes the ramp traffic held by the Sand Lake Signal backs vehicles up on half mile onto I-4 itself
Quote from: roadman65 on April 14, 2015, 11:55:35 AMActually I am looking not so much as overall traffic counts, but as traffic that backs up onto the highway.
Funny, I somehow got the impression you meant most heavily used interchange.
Perhaps the thread ought to be titled "most congested interchange for each interstate in your state" or something of the like that, you know, tells people what you're looking for.

Agree. "Most heavily used", by definition, implies "highest volume". Something can be congested if usage is relatively low if the design level is low.
Is the intent to exclude all freeway to freeway interchanges, or only those with other Interstates? If it's specifically Interstates only, then other freeway to freeway connections would account for a lot of them on the list. I-405 in California was mentioned earlier, and that has an obvious pick of US 101 if non-Interstate freeways are permitted. If not, then it's probably Century Blvd at LAX, or maybe Wilshire Blvd at UCLA.
North Carolina
I-85/Concord Mills Blvd (Exit 49), I actually remember reading somewhere that this was the busiest interchange in the state.
I-485/US 521 (Exit 61A/B) is probably up there somewhere too.
Defenitly the Zoo Interchange!

Driving regularly to and from Rochester, I would say that close to 50% of the westbound traffic on I-90 exits to US 52 (westbound), and likewise 50% of the (south) eastbound traffic on US 52 turns onto eastbound I-90. This percentage drops with peak vacation travel times to the Black Hills.
Malfunction junction in Tampa where I-4 and I-275 meet is a high volume interchange. It was just reconfigured recently (well back in the late 90's, early 2000's) to handle all the vehicles more efficiently.

Alabama:
I-10: Junction I-65 north to Montgomery and Birmingham -or- US 90/98, Daphne/Fairhope (Exit 35 A-B)
I-20/59: "Malfunction Junction" interchange with I-65, downtown Birmingham -or- US 82 (McFarland Boulevard), Tuscaloosa (Exit 73)
I-20 (separate from I-59): US 411, Leeds/Moody (Exit 144-A/B)
I-22: will eventually be I-65 north of downtown Birmingham
I-59 (separate from I-20): Chalkville Mountain Road (Exit 141), Trussville
I-65: "Malfunction Junction" -or- US 31 (Montgomery Highway/Columbiana Road/Lorna Road), Hoover/Vestavia Hills (Exit 252)
I-85: Junction I-65, south to Mobile, north to Birmingham -or- AL-271 (Taylor Road), Montgomery (Exit 9)
I-459: US 280, Mountain Brook/Vestavia Hills/Hoover (Exit 19)
What say ye, fellow Alabamians, concerning I-359, I-565 and I-759?
I-565 is either the interchange with I-65, AL 255, or Memorial Parkway (US 231/431). It's most likely the last one though.

Looking again at traffic counts, it very well might be US 52 that's the peak for I-90 MN.
Here's some guesses for Washington. I don't know where to find the actual stats. I excluded freeway-to-freeway junctions. Below, freeway-to-freeway refers to junctions that are entirely grade-separated and have no signals (so are either partial stacks, trumpets, etc) but do not necessarily connect to another freeway. I did not want to include junctions that were literally between two freeways, as those are easy picks.
I-5: Mercer Street (Exit 167), Downtown Seattle. Junction originally built for Bay Freeway (so it's freeway-to-freeway) but has become the main interchange for South Lake Union and points west.
I-405: Junction for either NE 4th or NE 8th near Downtown Bellevue (Exit 13B).
I-205: Mill Plain Blvd (Exit 28). I'm not including any of I-205 in Oregon.
I-90: Either the Bellevue Way or WA-18 junctions (Exit 9 and 25, respectively). Can't decide which. The former is freeway-to-freeway, but the latter is a diamond, so the 18 junction feels busier to me.
I-82: Most likely US-395 (Exit 113). Like others before, it's freeway-to-freeway, but US-395 is a very important connector between Canada and points south.
I-182: Most likely WA-240 (Exit 4). Also freeway-to-freeway. The 240 is a fairly important NW/SE connector road.
Washington has a lot of freeways without Interstate designation; this list would be very long if I included them all, but the original post just asks for Interstates, so that's what I've supplied.

For Michigan:
I-75: M-102 (8 mile) or Bridge to Canada (Exit 47)
I-94: Metro Airport (Detroit)
I-96: I-96/I-275/I-696/M-5 or I-96/M-39
I-275: I-275/I-96/M-14
I-696: I-696/M-10/US-24
Without looking at any stats, I would say I-94's exit 177 (State St. in Ann Arbor) would top the Metro Airport exits. I would bet I-69's would be somewhere in Lansing.
I'll take a shot at Idaho (these are based on personal observations, not data I found somewhere; I mostly am only in the Boise area so for other parts of the state I've visited less frequently, it may not be as accurate)
I-84: Eagle Rd. (ID-55)
I-184: Franklin Rd.
(note that the freeway-to-freeway interchange of I-84 and I-184 is by far the busiest intersection in the state, but it doesn't count in this thread)
I-86: US-91
I-15: Probably US-20
I-90: US-95
Non interstate you say?
MO
I-44 - US65
I-49 - MO150
I-55 - US60
I-64 - MO364
I-70 - MO370
I do not know for PA north of I-78, so I will only do the southern half of the state. I have also not been on I-276, and I-76 west of I-376. Here goes.
I-76: Tricky, but I'd say exit 236 (US 15). Traffic levels drop east of Harrisburg, and do not pick up until you are at Valley Forge.
I-78: Exit 51/53, as US 22 is I-78's emergency route east of Allentown. Also, I-78 gets clogged on the PA 309 concurrency, so a ton of traffic will clog US 22.
I-81: Hard for me, but I'd say Exit 65A-B or Exit 67A-B. US 11/15 is a great scenic way to get up to New York, while US 22/322 is a great way to get to Hershey or New York City (via 22 EB).
I-83: Exit 44A/Exit 45. Paxton St. will carry US 322 to Hershey, and PA 230 is the way around Harrisburg, and you could easily make it to the capitol via Paxton.
I-283: Exit 1, PA 283, since that is the fastest way to Lancaster.
I-376: This is completely different territory for me, but I would say Exit 72A-B-C. I am likely to be wrong, but that's the way to PA 28, I-579, and other major streets in Pittsburgh (traffic levels increase west of the Squirrel Hill Tunnel, AFAIK).
I-579: I don't know.
Quote from: noelbotevera on July 31, 2015, 02:34:36 PM
I-579: I don't know.
I don't know much about Pittsburgh but I would guess that most I-579 traffic is destined for the Liberty Bridge or Blvd of. the Allies (In turn trying to get to I-376). In that case the ending interchange would probably be the most used.

I would say the OP was very clear he's only interested in including interstate highway interchanges, and excluding Interstate-Interstate interchanges. No need to make the question harder than it is.

I'm going to help complete this:
I-79: Either I-70 Exit 19 (US 19) or Exit 78
I-279: Exit 1C (US 19/PA 65)
I-579: "Downtown Exits" (especially if you include the HOV lane)
I-80: Either Exit 210 (US 15) or Exit 302 (PA 33)
I-180: US 15/US 220/Future I-99 at the NT
I-380: Exit 3 (PA 940) or Exit 8 (PA 423/PA 611/Army Depot)
I-84: Exit 53 (US 6)
I-86: Exit 3 (PA 89). Only exit in the state. If the section in South Waverly is officially I-86 as Google Maps appears to indicate, Exit 60 (US 220) probably beats it.
I-90: Exit 24 (US 19). Nothing else comes remotely close.
Wisconsin
I-39/I-90: Interchange with the Beltline (US 12/18) Exit 142

I-41 might be close with WI 172 (Ashwaubenon interchange), too.
I-43 might also be WI 100 (Brown Deer Rd).
I-535 - 2nd St/3rd St (only interchange on highway in Wisconsin).
Where does WI 241 (27th St) rank on I-894?

Don't feel bad; pretty much nobody ever does these days. ;-)
(And not just here in this forum, but anywhere on the Internet, and in real life as well. I actually feel as if something has fundamentally changed in our society, where effect no longer follows directly from cause, nor response from stimulus. But maybe it's always been this way, and I just notice it more as I get older and more crotchety.)
