To get it started.... these are the ones that should either A: be a differnet type of interchange than they are or b: should not exist in the first place.
I-57 to I-55 in Sikeston MO. Yes i understand that it continues as a US route, but a 2Di to 2Di should not be done via cloverleaf ramps.
I-55 to I-55 in Memphis, when it goes onto the bridge. Nuff said, makes the ben franklin bridge situation look marvelous.
I-295 to I-295 via NJ42/I76
You didn't start with Breezewood? I mean, it all really works back from there (excepting such non-connections as 83 to 95, 78 to 478...).
New Jersey Turnpike to the I-195 westbound (Due to the tight curve, one can't go over 25 mph)
The I-195 westbound to the I-295 southbound (Similar tight curve and also one must then cross all of those exiting the I-295 southbound to get onto the I-195 eastbound)

At least they're working on this one, and in the meantime at least they finally separated 295 NB from 42/76.
More minor in nature, but I never cared for 95 thru the Blue Route/476 Interchange in PA. Shame they can't provide more than 2 thru lanes for 95.
I'll nominate the I-880/US 101 interchange in San Jose (http://goo.gl/maps/V58FF).
Both are major freeways but the interchange is a cloverleaf... :banghead: ...and, alas, there are NO planned improvements. :banghead: :banghead: :banghead:
I have never liked the interchange between I-77 and I-85 in Charlotte. Aside from two cloverleaf-style loop ramps, the other ramps involve somewhat sharp curves, especially the ramp from southbound I-85 to southbound I-77.
I also dislike the interchange of I-83, I-283, and US-322 east of Harrisburg. I think part of it is the use of one-lane ramps for the thru movement on I-83 and for the connections to I-283. The only multiple-lane thru connection there is between US-322 and I-83. I suppose from my point of view that ought to be fine because 99% of my trips through that interchange are en route to Hershey Bears hockey games, meaning I use US-322 to Hershey, but for some reason it always feels like a chaotic little area. Last time we went up there I took I-283 instead for clinch purposes (connecting west via the Turnpike) and I liked it better than that stretch of I-83.
Two of the ones I would have listed in the past (I-66/I-495 in Virginia and I-95/I-695 in Maryland, both of which were plagued with left-side entrances and exits) have been rebuilt and I no longer think they're all that bad.
The Circle Interchange (I-290 & I-90/94) in Chicago.
I-294 north to I-290 west in Hillside, IL. I hate that fucking loop ramp.

93/95 (in Reading) is a full cloverleaf, and is fine (except for the traffic, but that's due to the number of lanes decreasing).
As for bad freeway transitions, sometimes a sudden end onto a surface road is a problem (MA 128's rotary, Lowell Connector's northern end)

Actually, the lane drop along I-95, north of I-93 occurs at the next cloverleaf interchange (MA 28) and the traffic north(east) of I-93 usually loosens up. Of course & as many here already know, that cloverleaf wasn't a 2di-2di junction when it was first constructed.
Breezewood is too easy to nominate, and it actually works well enough despite the traffic light. it isn't outright dangerous like some of the others we can nominate.
One i never liked, 295/US40/Turnpike on the NJ side of the delaware memorial bridge, i understand that 295 was an addition to the area, but it could have been handled better.

I'm also not a fan of the I-10 East to I-12 West and I-12 East to I-59 North ramps near Slidell, LA. The first is a rough, poorly angled left exiting flyover, while the second is a loop ramp that's just a bit too tight.

If I'm passing all the way through the area, I prefer to use 581 around the west side of the city instead of passing through the various substandard areas along I-83 there. Much better road. But usually if I'm up there it's to go to a Bears game.

Sure it can, if traffic volumes don't warrant more. Let's see...
I-84 at NY 17/I-86 (whenever they uncover the signs)
I-79 at I-90
I-79 at I-80
As people have already said, there are quite a few more that I won't even bother to list. If we include interchanges with one flyover and 3 conflicting loop ramps, that number goes up immensely. Most interchanges just don't have enough volume on adjacent movements to warrant something that doesn't involve weaving, especially if you're in a relatively rural area.
Indiana Toll Road at the Borman Expressway, Lake Station, Indiana. The intersection of 3 mainline interstates, plus one US route and one state route. It's a modified double trumpet that was designed to accommodate a toll booth that's been gone for decades. I recall that it's been discussed in either the Redesigning Interchanges thread or perhaps the Great Lakes board, though I can't find the discussion. This transition stinks.
It could also be mentioned that WB ITR to WB Borman ramp, which carries the I-80 mainline, has been closed for months, forcing I-80 traffic to continue on the ITR to the I-65 exit, which is ugly also. A single lane of traffic snakes through a series of ramps. A replacement ramp at the Borman has been promised. I'll believe it when I see it, considering the bankruptcy of the concessionaire.

I-10 and I-295 in Jacksonville...the NB I-295 to WB I-10 loop ramp is a royal pain, especially when you're in the middle of a conga line of tractor-trailers.
Capital Beltway at Baltimore-Washington Parkway with the MD193/Greenbelt Road interchange with the Parkway literally right on top of you. The weaving...it burns!
I-4 at SR 408 (East-West)...'nuff said.
I-76 and I-676 in Philly...seriously, they've rebuilt this interchange twice since I was a kid and it still isn't right (although they did eliminate the 30th Street Station SB "deathramp" onto the Schuylkill)...

I hate that loop ramp too. My aunt's house is in viewing distance of that ramp (which is technically in Berkeley, not Hillside), and I've often sat on her deck shaking either my head or my fist at it.
I also agree that something needs to be done about the 290E to 294S/88W ramps. It needs another lane in addition to your suggestions, though, in my opinion. Complicating matters is the Saint Charles Road exit which is right in the middle of the mess.
Also, there's the 290E to 294N transition, which uses the surface streets of North Avenue and Lake Street, should probably be fixed in some way, too. There's too much traffic trying to go in too many directions there. And with the cars and especially trucks crossing two lanes of traffic, it can take a while to get through.
I-75 to I-75 in Detroit.
The Mid-County Interchange in Philly is confusing and due to PA keeping the original exit that was before it, has weaving issues.
I-695 to 695 on the northern end of the baltimore beltway, after the bridge heading towards 95, when it has to make a 90 degree turn to just stay on itself for the windlass.
I-95 to I-76 in philly is just a disaster caused by the decade or two of differnece in construction dates.
This thread's growing at an alarming rate, so if I'm repeating, there's more than I can follow.
I-93 at I-95/Mass. 128, Reading, Mass.: if traffic backed up just because of volume on the receiving road, it would be one thing, but traffic backs way up going into a free-flowing road because of a narrow, tight ramp. Another cloverleaf's abilities exceeded.
Old story, one where the state actually gave up in its last effort to fix the problem due to the level of local opposition to the Takings. But it's a shitty situation in the meantime.
And I've only done it a few times, but I have bad associations with I-70 to I-79 in Washington, Pennsylvania. The pavement was always cruddy on a tight ramp when I was through there.

I-40/77 in Statesville (being worked on now)
I-40/26 in Asheville (left exit to East I-26 from I-40W with almost no accel lane?)
I-5 / SR 520 in Seattle is pretty bad. The left-handed exit/entrance for southbound I-5 creates a bad weave that forces drivers to cross 5 lanes of traffic to exit at Mercer Street, which regularly backs up I-5 traffic to Northgate and beyond.
And it's getting an "improvement" in the form of a new ramp to the reversible express lanes (http://www.wsdot.wa.gov/Projects/SR520Bridge/I5ToMedina/I5toMedina_Design.htm), but nothing to solve the left-handed exit.
I-95 and I-26. The biggest movement is 95n to 26w and its a cloverleaf.. Lots of truck traffic too

There are people here who know that answer better than I do. The last I heard, it remains in the long-term vision. However, sometime over five years ago, I recall actual public meetings that had so much opposition that the process was stopped completely because there were better things to do with the money available than sit on it for a project that didn't have any chance of moving forward soon. This is probably well documented in the archives of ne.transportation and misc.transport.road.

I-75 south to I-75 south in Knoxville. All I-75 southbound traffic is funneled onto a one-lane ramp. I've seen huge backups there. You're better off taking I-275 (which was I-75 until I-75 was routed onto I-640) south to I-40 west.

Thank you for nominating Kansas City's wretched downtown freeway loop. However, I think the worst of all the movements is NB I-35 to NB I-35. Following NB I-35 involves a
mandatory two lane changes to the left within a distance of one mile, simultaneous with EB I-70 making one or two lane changes to the right within the same stretch.
What Kansas City does to NB I-35 is worse than what Breezewood does to EB I-70. At least, when following EB I-70 through Breezewood, one can stay in the same lane after going through the toll plaza (by taking the left lane after the toll plaza, which becomes the right lane after the left turn), and the competing lane changes required of WB US 30 are done at a relatively slow speed, rather than ~60 MPH.
I think at least half of Kansas City's downtown freeway loop should be removed and converted to surface streets/boulevards. I'm not sure yet what to do with the other half (but this would be a "Fictional Highways" topic).

Columbus has the same issue on several highways. Through traffic on I-71 has to move 2 lanes to the left within a mile to stay on.
Just south of the western end of the concurrency, I-71 traffic in both directions has to switch between the inner lanes (to/from south) and outermost lane (to/from north) within 1/2 mile (NB) or ~3 miles (SB). A couple miles west of here, I-70 traffic in both directions has to make 1 or 2 lane changes between I-270 on the west side and I-670. I-670 WB requires a lane change for WB traffic coming from I-71 SB or I-670 east of I-71 due to the layout of the I-71 interchange.
Because of this, it is currently (and likely will be for a long time) impossible for someone traveling between the south/west I-270 and north/east of downtown via I-70 and/or I-71 to remain in the same lane. Worst offender is I-71 NB, which requires a minimum of 4 lane changes (2 right, 2 left) in under 5 miles.

US 15 and PA 581. What should be a freeway-to-freeway interchange has two traffic lights, and a left turn across (US 15 south) traffic to get on PA 581 west. At least one flyover ramp is needed, IMO. Also, another exit on US 15 is too close to the interchange.

PA has a bunch of these in general. Everything with I-76 is a mess. I-80 at the Northeast Extension is a double trumpet with a traffic light right in the middle of it. I-81 at the Northeast Extension is no better, with a triple trumpet and hairpin curve at the northern one and an indirect connection at the southern one. And
every flipping interchange on the Turnpike has an insanely tight trumpet.

I've been through that interchange twice en route to Niagara Falls and for whatever reason we ended up passing through during rush hour. This interchange is so under-capacity and awkwardly designed that it's hard to pick out any kind of thru route.
Preliminary design work has already been done on a major reconfiguration of that interchange, and it will establish I-83 as the primary right of way as it curves through. Reconstruction is expected to begin later this decade.
The westbound I-80 connexion between the Indiana East-West Toll Road and its concurrence with the I-94. It has been closed. It is being rebuilt but to the original design. This is like buying a brand new Model T.
In addition to a ramp with a steep incline to a tight curve, there involves cross traffic with cars coming from Chicago going to Michigan.

PA has a bunch of these in general. Everything with I-76 is a mess. I-80 at the Northeast Extension is a double trumpet with a traffic light right in the middle of it. I-81 at the Northeast Extension is no better, with a triple trumpet and hairpin curve at the northern one and an indirect connection at the southern one. And every flipping interchange on the Turnpike has an insanely tight trumpet.
Turnpike interchanges are really goofy. Aside from the 2 plainly obvious connection malfunctions, the Mainline does not connect directly to I-81, I-99, or the US 219 freeway. Nor with I-176 till sometime in the last 10 years or so. It's pretty close at I-99 though... The Turnpike-US 222 interchange is odd, too (diamond at 222, trumpet at turnpike).
Double trumpets annoy the hell out of me, but especially in a situation like the I-76/I-80 interchange in eastern Ohio where the designations swap alignments..

If they were smart they would utilize the stubs at the hairpin for the never built continuation of the Extension, and have a direct roadway into I-81 at a semi directional interchange there. Leave the triple trumpet as is for connections to and from US 6 & 11 and SB I-81 which probably has hardly any connection to being the previous exit connects indirectly with I-81 further south.

Don't get me started on that one. EB I-76 has to use
both of the loops, while EB I-80 gets a pretty smooth connection.
I-71 North to I-480 West in Cleveland: Due to the freeways being shoehorned between Brookpark Road and two sets of railroad tracks (one is part of a railyard), there is a very tight loop from I-71 to I-480 and then through-480 traffic has to weave with WB-I-480 traffic bound for SR-237 South towards the Airport.
Honorable mention is the Central Interchange in Akron (I-76/I-77/SR-8), although there are plans to (slowly) rebuild the entire 60 year old interchange.

The westbound I-80 connexion between the Indiana East-West Toll Road and its concurrence with the I-94. It has been closed. It is being rebuilt but to the original design. This is like buying a brand new Model T.
In addition to a ramp with a steep incline to a tight curve, there involves cross traffic with cars coming from Chicago going to Michigan.

Indiana Toll Road at the Borman Expressway, Lake Station, Indiana. The intersection of 3 mainline interstates, plus one US route and one state route. It's a modified double trumpet that was designed to accommodate a toll booth that's been gone for decades. I recall that it's been discussed in either the Redesigning Interchanges thread or perhaps the Great Lakes board, though I can't find the discussion. This transition stinks.
It could also be mentioned that WB ITR to WB Borman ramp, which carries the I-80 mainline, has been closed for months, forcing I-80 traffic to continue on the ITR to the I-65 exit, which is ugly also. A single lane of traffic snakes through a series of ramps. A replacement ramp at the Borman has been promised. I'll believe it when I see it, considering the bankruptcy of the concessionaire.

I appreciate your mention of the weaving problem with Chicago-Detroit traffic--yet another headache that won't be solved. We're going to have the shiniest Model T ever.
Since Cline Avenue is technically a freeway...
The transition to and from the Toll Road (near the Gary Airport) has to be up (or down?) there. An extremely tight loop ramp on the Northbound exit to the Toll Road (ramp speed is advised at 15 mph), complete with a traffic light and the base of the ramp. The other end of the interchange is met with a four-way stop, and drivers could be stopped by service trains before entering Cline Avenue southbound.
I know it was a sign of the times amid a then-growing industry, but this is still a poorly-served freeway-to-tollway transition.

Most folks going from Chicago to Michigan use I-94 straight through. It avoids the overpriced Skyway toll and the two Indiana tolls (Westpoint and the ramp toll plaza). It's well reflected in the traffic counts between the two routes.

Cline Avenue has to be one of the weirdest freeways I can think of. It just feels cursed considering all the bridge issues.
I'd also like to nominate the US 22-322 East to US 11-15 North movement in Duncannon, PA as very odd. (You could technically argue that this isn't a freeway-freeway connection I suppose)
Seconded on anything I-83 in Harrisburg, and the 15-581 interchange. It is better than it was, but that left turn light gets backed up bigtime at rush hour into the through lanes.
I-39 onto I-90 in Illinois used to be terrible, but looks like they've fixed that one. It had been a very tight trumpet and had remainders of the tollbooth that had previously been there.
US 24 Fort-to-Port at the I-469 interchange.
US 30 at I-75 (via Ohio 696).
I 10/ I 110 in Baton Rouge. I 10 EB has to slow down to continue east or go on 110. 110 SB to 10 WB is horrible.
I-195 north to I-95 north in the Bryan Park Interchange near Richmond, VA is a traffic bottleneck during rush hour as it begins as a 2-lane ramp, becomes a 1-lane ramp as it crosses over eastbound I-64, then has traffic from eastbound I-64 merge in from the left, becoming 2 lanes again. Then, shortly before the ramp meets I-95 north, the left lane ends, and there is very little time to merge onto I-95 before the merge lane ends. Making matters worse is that there is no deceleration lane for the VA 161 exit about 1000 feet ahead.

I-695 to 695 on the northern end of the baltimore beltway, after the bridge heading towards 95, when it has to make a 90 degree turn to just stay on itself for the windlass.
Yep, because (in brief) the straight route was dropped in favor of the connection with the Windlass Freeway, which was not built beyond that section.
Another nomination is the I-695 and I-70 interchange, which becomes a bottleneck from I-70 east to I-695 north due to I-70's cancellation east.
An awkward section of highway is the rapid string of interchanges along I-70 with US 40, I-270, and US 15/US 340. The through traffic is ultimately left with one lane.

Now that you mention single lanes for through routes, I-95 south at the interchange with I-495/I-295/DE 141 had one lane continue the whole way through, then that lane exited off at DE 1/7. The leftmost lane exiting Wilmington would bear left for I-295, the center would continue along the mainline until DE 1, and the rightmost lane would exit at DE 141. Just recently has another lane been added as a result of I-495's closure, so there's a single lane of I-95 south traversing the whole state.
On a similar note to what bassoon1986 said on page 1 (I 30-Loop 12 Dallas), the connection between the I-30 and SH 360 freeways is a pain! Odd movements, too much traffic and a light at Six Flags Dr. To get from SB 360 to WB 30, you need to exit for Six Flags Drive, sit at a light, go left, sit at the light with the other frontage road, continue a bit then turn, cross I-30 and make a tight loop ramp onto I-30 West itself. The area's always super-busy due to Six Flags, Rangers Ballpark etc, and the lights aren't timed too well. To add insult to injury, there is a brand-spankin-new section of freeway on I-30 just a mile to the west. Gotta love them old turnpike interchanges! :pan:
-End Rant-
81/26 interchange in NE Tennessee is ugly. Cloverleafs, interstates with fairly heavy traffic-loads (more cross-country traffic on I-81, more local traffic on I-26). One of those deals where each interstate direction (which is only 2-lanes across the board) has a real short lane where traffic needs to merge both left and right between the various ramps.
More local to me, the I-275/I-71 interchange in Northeast Cincinnati is MOSTLY good. Where it's not is going from I-275 West to I-71 South, or I-71 South to I-275 East (this movement in signed horribly, in addition to its other faults). Cloverleaf interchanges in those instance, I honestly don't get why they didn't do flyovers for those movements (as they did for others in that interchange).

How about US 23 to the Ohio Turnpike? Forcing traffic leaving out of the non-Detroit parts of Michigan to use surface streets in Maumee seems a bit weird, especially US 23 crosses the Turnpike at some point.

Also right there in that area, 480 east to 237 south and 237 north to 480 west. I hate dealing with that anytime I go to or from the airport.
In both directions you get dumped on Brookpark Rd and have to deal with traffic lights and left turns, with 237 to 480 being the worse direction of the two (4 total lights, 2 left turns and 1 right turn)

When the Salisbury/Dussell Drive ramp at US 23 was completed in the late 80s, it was a vast improvement over the US 24 / OH 2 routings to US 20 and the Turnpike. But Dussell quickly got built up with business parks, hotels and other retail and is just as slow going now as the roads it replaced as the suggested route between US 23 and the Turnpike.
Since it's been about 10 years since I was last thru there, and much of the Southwyck Mall area is now gone, anyone know if you can make better time to US 23 North via OH 2 nowadays???
I'm surprised no one has mentioned the I-90/I-91 interchange in West Springfield, MA. The interchanges are not truly direct, as they are separated by a connector road that feeds from 91 down to US 5. Basically, two trumpet interchanges that meet perpendicularly. Another terrible one is I-95/I-395 in CT. The moves from I-395 South to I-95 North and I-95 South to I-395 North involve using CT 85, or a SUV through the woods.

I think the I-95/ I-395 thing is waiting for CT to complete CT 2 as it would tie into that interchange if or when it gets done.
The big issue is not really that as much as the weaving issue for SB I-95 to exit at US 1 afterward as you have to compete with I-395 motorists merging in. Hopefully if and when CT 2 is completed, that they will address that issue as well.

While slightly longer and more complicated navigation, wouldn't traffic from the east use I-280 and I-475?
And most traffic from the west can use I-94 or I-69 to get to most of Michigan.

Yeah. The PSB is brutal. Those ramps are scary enough, but throw in a good rainstorm.
Here are two that have since been fixed:
I-170 at I-64. Before 64 was rebuilt, this intersection was bad. That tight ramp to 64 east caused some spectacular traffic.
MA-3 to US 6 at Sagamore Bridge. When the rotary was there, it was pretty nasty. The flyover has helped, but not by much.

I-90 and I-291 in Chicopee MA. Yeah, it's a direct connect, you just need to sit thru a traffic signal to take the left turn on I-291 after the toll booths. I seem to always hit the worst of traffic the few times I've ever had the pleasure of going through it.
I-75 and US 30. Some excessively long (and slow if you're behind a truck) movements for admittedly relatively few drivers.
I-76 and I-80 bump. For multiple reasons.
IMHO, one of the worst is/was coming out of Youngstown, OH from I-680 South onto the turnpikes east. If you do not have an EZ Pass, you stop to pick up a ticket as you enter the Ohio Turnpike East. Drive about 5 minutes or so, then surrender the ticket and toll at the east end of the Ohio Turnpike. Drive again not even 5 minutes and now you pay the entrance toll for the PA Turnpike Barrier.
Not as big of an issue now if you do have the EZ Pass, as there is no reaching for tickets or cash anymore.
The I-26/I-240/U.S. 19/U.S. 23 junction in Asheville, NC is shitty. I drove I-26 (south)eastbound through Asheville and damn near ran off the highway after exiting onto the I-26/I-240 multiplex and crossing the French Broad River. I didn't realize that I-26 exited itself again immediately on the other side of the river. NCDOT needs to do something about that entire arrangement, Asheville hippies be damned.
And though I've never driven them, two interchanges between highways in Ohio look pretty goofy: I-71/U.S. 35, and I-75/U.S. 30.

In the case of the former, they just used the existing interchange with the old alignment of US 35 instead of building a new one so close to the old one.

For that matter, the way I-76, I-77 and I-277 all interact with each other in Akron is a clusterfuck too. I-76 has a trumpet interchange with itself on the west side of the city.

The plan for I-80 was for it to use current I-76 east of I-77 and I-77 between Akron and US (now SR) 21. From there, it would have gone due west, eventually meeting up with the current alignment (hence the stubs at this interchange). I-76 was assigned much later and the current routing was not intended to carry a single designation. US 224 was the only designation for what is now I-277 and I-76 west of I-277.

I-5 / SR 520 in Seattle is pretty bad. The left-handed exit/entrance for southbound I-5 creates a bad weave that forces drivers to cross 5 lanes of traffic to exit at Mercer Street, which regularly backs up I-5 traffic to Northgate and beyond.
And it's getting an "improvement" in the form of a new ramp to the reversible express lanes (http://www.wsdot.wa.gov/Projects/SR520Bridge/I5ToMedina/I5toMedina_Design.htm), but nothing to solve the left-handed exit.
If they were smart, they would simply use that ramp to connect to the SB Express Lanes Mercer exit, and use the NB Express for NB and SB Express to Mercer transition, or simply use a barrier to prevent people from going over to Mercer Street from 520, there a half-dozen other exits to the North and South which are usually more useful to access downtown than Mercer ever was. The only other solution would be a direct ramp from 520 to Mercer, as a right exit would introduce huge weaving issues, and everyone in the area would fight it tooth and nail.
Prior to 1993, I would have said that the SR 526 to I-5 interchange was bad, where you had to go through traffic signals for two movements.
The I-90/I-43 interchange is bad, as well as the I-39/I-90 Tri-State Interchange, at least, the last time I drove through it, which was 2008.
Then there is alway I-180 in Cheyenne. Enough said.
I-680/I-29 with CR-988. That is a strange thing to say the least.
At least they are finally fixing I-80/I-29.
OR 22 at I-5.
OR 217 at I-5.
I suspect OR 213/224 at I-205 will be a candidate once the Sunrise Freeway is built (interchange currently under construction). In short: A freeway-freeway interchange should not have lights.

I'll nominate the I-880/US 101 interchange in San Jose (http://goo.gl/maps/V58FF).
Both are major freeways but the interchange is a cloverleaf... :banghead: ...and, alas, there are NO planned improvements. :banghead: :banghead: :banghead:
About as bad as the I-580/I-680 Interchange in Pleasanton, CA (https://www.aaroads.com/forum/index.php?topic=12811.msg309729) that I hate so much.
I'd nominate I-240 south to I-240 east in Memphis. Having two lanes is fine in theory, but the geometrics are a mess and you have heavy traffic merging from I-55 north to I-240 east that has virtually no space to merge, and which then needs to merge left again to stay on I-240 a few hundred yards later.
The Texan speciality of requiring freeway-to-freeway movements via the frontage roads is always fun too.
Speaking of Texas, does not the I-410 Loop have a strange transition at the NE Junction of I-35?
I always found the interchange between I-84 and I-205 in Oregon to be, well, bizzare.
Wouldn't it have made more sense for 205 and 84 to briefly merge, before 84 banks east and 205 continues north into Washington?
