Interstate to Interstate Slow-speed Exits

[Jordanes]

What interstate to interstate connections are not full expressway-grade? I don't mean things like Breezewood, I mean more like just slow-speed connections, or with weird exits as part of it? The one which comes to mind to me is I-64 east to I-564 east, or the reverse of I-564 west to I-64 west. It's rather slow-speed, and there is an exit to Granby Street sandwiched in there, too. What other examples exist?

[jp the roadgeek]

I-84 to I-91, with the exception of the connections made by CT 15, are all slow speed (35 MPH, I believe).  I-91 is I-95 are pretty slow speed (40 MPH).  Any interstate that connects to an interstate that is a closed ticket toll road is going to be low speed because some will have to stop and take a ticket or pay a toll, and many have EZ-Pass lanes with a 15 MPH or lower speed limit. I-95 to I-87 is always a no speed connection because it's always backed up

(Extended) Chicago area and Northern IL:

I-80 thru from the Indiana Toll Road/I-80/90 to the Borman Expressway/I-80/94 in NW Indiana, using the Dual Trumpet...

I-294/Tri-State Tollway North to I-55 South

I-55 and I-80, full Cloverleaf

I-39 and I-88, full Cloverleaf

I-39 and I-80, full Cloverleaf

Downtown Chicago, I-290/Eisenhower Expressway and I-90/94/JFK Expressway/Dan Ryan Expressway/the Jane Byrne Circle Interchange

I-294 North/I-88 East to I-290 West

I-290/IL-53 and I-90/Jane Addams Tollway, full Cloverleaf

I-355 North to I-55 South

I-80 and I-88, full Cloverleaf

I-74 and I-280, full Cloverleaf

I-74, I-80, and I-280, full Cloverleaf

Louisville: Any Interstate movement involving I-265

Sikeston, MO: I-55 and I-57/US 60: full Cloverleaf

Down in Memphis, I-55 North thru traffic to cross the Mississippi...

Really, isn't any Interstate to Interstate movement with a Loop ramp a low-speed connection?

My favorite, tho, is probably I-76 and I-80, when I-80 Eastbound leave the OH Turnpike, or I-76 Westbound leaves the OH Turnpike, on the Double Trumpet, especially since the Interstates technically don't Intersect, despite having an Interchange -- they "bump"/touch at a Point

I-81/I-476 (northern one) is very slow speed.  Triple trumpet design (with US 11), stop signs on the ramps (pretty sure 0 mph counts as "slow") despite not having at-grades, and that 35 mph curve on the I-476 mainline (with the limit continuing another mile south for some reason).  Also, toll booth.

I-81/I-90 is your typical Thruway double trumpet.

I-90/NY 85 also has a very tight loop ramp.

[JJBers]

I-84 to I-91, with the exception of the connections made by CT 15, are all slow speed (35 MPH, I believe).

Since it's clogged half the time, it's mostly driving even slower than that.

[US 89]

In SLC, both loop ramps at the I-15/215 south interchange and the loop ramp at the west 215/80 interchange have 25 mph advisory speed limits.

[Sykotyk]

I-79/I-80. It's a tight cloverleaf, so four direction (E-N, W-S, N-W, S-E) are tight turns signed at 25mph for trucks. Even the outside curves for the other four changes aren't that fast, either as they hug the cloverleaf tightly instead of allowing a longer straightaway.

[Scott5114]

Most of what you're going to see listed here are cloverleafs, I think.

I-44/I-235 and I-35/I-240 definitely both fit the bill (although both are in the progress of being upgraded with a couple of flyovers).

[SectorZ]

All of them in Massachusetts, maybe except for 95/495 in Salisbury.

[Rothman]

I-91 to I-391 isn't that slow, is it?

[froggie]

SB 91 to NB 391, and its reciprocal, have a 30 MPH advisory.  Appears to meet the OP's criteria.

[SteveG1988]

I95 to i76 in Philadelphia. Slow, missing movements, any eastbound connection has to use city streets.
I76 to I76, From the toll road to the free section of 76. Trumpet, toll booth.
I69 to I24 in Eddyville KY. Trumpet type.
I55 to I55 in St Louis MO. Tight Ramps, 15mph
I195 to I95 in NJ. Double Trumpet with the Turnpike.
I78/i95/Turnpike Newark Bay Extension. i78 must come to a complete stop, slow ramps to connect beyond the booths.
I20 to I285 Atlanta. Left hand exits with a tight turn coming from 285, tight ramps going from 20 to 285 on the western end, eastern end is just as bad. All trucks must use it yet they haven't thought about making it safer for them.
I49 to I49 via I44. Going north off 44 through carthage MO is a tight ramp and substandard. The connection to 49 through Joplin from 44 is not as bad but isn't optimal.
I81 to I77 in Wytheville VA, weird configuration all around on both ends.
us50/I595 and I495/95 in Maryland/DC area. A mess.

[Michael]

The I-690 westbound ramp to I-90/Thruway is pretty tight.

[hbelkins]

I-64 east to I-75 north. A loop ramp with an advisory speed of 25 mph.

[DeaconG]

I-76 to I-676 (Schuylkill to Vine) in Philly, been rebuilt twice and still a mess.

[GaryV]

Michigan (Detroit) I-75 to I-75, 25 mph as I recall.

Any freeway-freeway interchange in Los Angeles County or Orange County in California that features a ramp meter on the ramp (yes, these are pretty common in the Southland). Here's an example on a ramp leaving the impressive stack interchange at the junction of I-405 and I-105 (traffic from I-405 southbound to I-105 eastbound) near LAX.

Here's a view of the stack from the northbound lanes of I-405.

I have never heard of ramp meters on freeway-freeway interchanges. Is there any other place besides south CA that has them on these?

[fillup420]

I-73 N to I-85 S. Full cloverleaf. Definitely left over from when I-73 was just US 220

I have not seen them elsewhere with my own eyes, but I have been told that they do exist in other places.

This is common in the Twin Cities.

[froggie]

I would also consider the ramp meters a special case, as they typically operate during peak periods where your mainline is likely slow and congested to begin with.

[GenExpwy]

I-90 to I-390 southbound in Henrietta, NY has YIELD signs. This Interstate-to-Interstate movement must yield to traffic entering I-390 southbound from Lehigh Station Road.

[Revive 755]

I55 to I55 in St Louis MO. Tight Ramps, 15mph

Assuming the advisory speed has not been reduced since the last time the Streetview van or I was through there, those are 20 mph ramps (when not at a stop due to congestion).  Streetview of advance sign for northbound I-55

Also I-55 NB to I-44 WB a few miles to the south - a nasty 20 mph left side to left side ramp.

[SSOWorld]

I-39 SB to I-90/94 NB near Portage, WI

I-43 ends at a cloverleaf with I-90 (The interstate replaced WIS 15 as the designated route #)

I-90 WB to I-39 SB at Cherry Valley (Rockford) IL - leftover ramp from the former trumpet. (Another overlay interstate in 39)
