Title: Least traveled interstate ramps/connections
Post by: Roadgeekteen on May 14, 2020, 10:45:54 PM
Mentioned in another thread, very few people travel from I-57 north to I-24 or I-24 to I-57 south. Also, no ramp, but I can't imagine many people going I-40 west to I-15 north and vice versa. Any other examples?

I feel like I-57 south to I-55 north could be used by people in extreme southern Illinois going to St. Louis.

It would be about 10 minutes slower vs. IL-3 and IL-146 into Cape Girardeau to I-55.

I'm not saying any of those connections aren't used, but they have generally low traffic volumes compared to the other connections based on the way the highways approach each other. For instance, all the other connections at the I-55 / I-57 / US-60 interchange would have higher volumes than that particular movement. I didn't confirm any of these with actual AADT counts, but this is just largely assumptions based on the highway locations and population centers.

Also maybe I-70 west to I-15 north, as most traffic would have departed on either US 6 or US 50.

Can't imagine a whole lot of traffic using the I-15 north to I-84 east connection (or vice versa) via SR 26 near Ogden, unless your origin/destination is in a very specific area of northwest Davis or southwest Weber County south of 4000 South and north of SR 193. US 89 along the Layton east bench is a much better alternative.

Back when I was living down there (pre-late 2012) the ramps from NB I-215 to SB I-15 and vice-versa at Devore didn't get much use, especially after CA 210 was completed out past 215 in 2007.  However, the last time I was on I-15 a bit over a year ago there were plenty of new huge warehouse/distribution facilities lining I-15 just west of the Glen Helen event site, which could mean that those ramps might get utilized quite a bit more than previously, particularly with trucks coming or going from I-10 east of the San Bernardino/Redlands area (that routing would be the most efficient way for that to happen).

In Michigan, I have to think that I-75 south to I-275 north, and I-275 south to I-75 north, get very little use.
Title: Re: Least traveled interstate ramps/connections
Post by: TheHighwayMan3561 on May 15, 2020, 02:09:28 AM
Minnesota typically does a good job of omitting redundant connecting ramps (see. SB 35W-EB 94, EB 494-NB 169, WB 94-EB 610, no return access between 35W and 35E unlike in Texas). One exception is southbound US 169 to westbound US 10 in Elk River, where 169 has three streets with local access, two of which directly connect to US 10 and making that ramp useless.

Another possibility is I-696 wb to M-5 eb, and vice versa.
Nor, at the same interchange, I-275 nb to M-5 eb, and vice versa.
You do see vehicles using the loop ramps for M-5 to/from the I-696 to I-275 ramp, but not often.

The one in Iowa I doubt gets used very much is the exit from eastbound I-680 I-880 to westbound I-80 and vice versa. I suspect the use of those ramps is 100% directly related to the use of the IA 191 exit.

While I don't doubt the need for it, the ramp from I-35 SB to I-90 EB and the corresponding I-90 WB to I-35 NB must not get used very much at all. I suspect the only people who use them are going to or from Clarks Grove, Hayward, or the KOA at the old US 16 exit east of Hayward.

Isn't there a "private use only" ramp somewhere?

Post by: 1995hoo on May 15, 2020, 08:40:29 AM
This situation no longer prevails due to reconstruction, but for many years, I-495's Inner Loop in Virginia had two exits to westbound I-66, one from the left lane (the original exit dating back to when the roads opened) and a right-side loop-around ramp added some years later in part to help reduce the problem of traffic entering from US-50 and having to cut across four lanes of traffic to the left-side exit in a very short space. Very few people used the right-side exit, even people entering from US-50 (they still cut across all four lanes), and I'd wager the traffic counts would probably show it was severely underused compared to the overall volume of traffic changing direction at that interchange.

That situation no longer exists because nowadays, the left-side ramp is an HO/T exit and everyone in the "free" lanes has to use the right-side ramp, though it will be reconfigured into a flyover instead of a loop during the next few years as part of the I-66 outside-the-Beltway HO/T project.

I-78 WB to I-81 NB and vice versa - similar to the Iowa example, I would guess that the main purpose of these ramps is to allow local access to/from the PA 72 exit just to the north.
Title: Re: Least traveled interstate ramps/connections
Post by: NWI_Irish96 on May 15, 2020, 08:52:43 AM
The ramps are shared with other more frequently used movements, but these particular movements are pretty rare:

I-80/90 WB -> I-94 EB
I-80/94 EB -> I-90 WB
I-90 EB -> I-80/94 WB
I-94 WB -> I-80/90 EB

Been there, done that. I live in STL and have cousins who live near the 55/24 split (most conservative people you'll ever meet in your life, but that's for another thread). Although usually 57 to 64W in Mt Vernon is the way back, we have gone 57 to 55N before (and through Cape Girardeau).

There's this rail yard access from I-70 WB in Kansas City:
https://goo.gl/maps/N9VJfM1XyA7YhqNcA

There are also direct ramps into a variety of federal facilities around DC (e.g. NASA Goddard, the NSA), but none of these that I can think of are on interstates.

This basic situation still exists with the I-64/264 interchange in Norfolk: https://goo.gl/maps/r5n2xcSxZcu64vwc6

From EB I-64 to EB I-264 there's a loop ramp, a flyover, and a HO/T flyover.
From EB I-264 to WB I-64 there's both a loop ramp and a flyover.
From WB I-264 to EB I-64 there's both a loop ramp and a flyover.

Most of these loop ramps still exist as they connect to/from the C/D roads, where the flyovers connect directly to/from the main lanes.

Oh, I also can't see I-90 east to I-84 west being used a lot.

AADT = 2082

US-20 WB → I-84 WB actually has a lower AADT.

Do you have the AADT for the exit on MA 2 that I mentioned?

I can. What about those who live on MA/CT 131?

I'm not saying the nobody uses it, but it's probably the least used interstate ramp in Massachusetts.

Exit 37A on MA 2 westbound?

Not an Interstate.

But, because you asked again...

AADT = 96

The northbound-to-westbound ramp is even lower, at 46.

The main ones that comes to mind in New York are I-86 EB - I-390 NB and I-390 SB - I-86 WB (https://www.google.com/maps/@42.3892549,-77.3865021,16z). Surface roads are faster for any move between the I-390 corridor and the west aside from origins/destinations right at I-390 Exit 1. NY 36 is the preferred route between I-390 and Hornell, while NY 21 is faster to Cohocton or Wayland.

Another possibility is I-696 wb to M-5 eb, and vice versa.
Nor, at the same interchange, I-275 nb to M-5 eb, and vice versa.
You do see vehicles using the loop ramps for M-5 to/from the I-696 to I-275 ramp, but not often.

There actually is more traffic on those ramps than you might think because of vehicles going between all directions of I-96/I-275/I-696 and the M-5/Grand River Avenue/Ten Mile Road interchange; that short stretch of M-5 is a well-used spur to connect all those freeways with the surface road grid.

The ramps are shared with other more frequently used movements, but these particular movements are pretty rare:

I-80/90 WB -> I-94 EB
I-80/94 EB -> I-90 WB
I-90 EB -> I-80/94 WB
I-94 WB -> I-80/90 EB

Bolded emphasis mine.

I think that ramp movement gets a little more usage than expected only because it’s the required movement for Toll Road traffic in either direction to access Indiana 51 south. Otherwise, there really isn’t a reason (outside of construction or major accidents shuttering the I-65 ramps nearby) to make that movement - a point rather subtly made in the exit signage for eastbound travelers (no mention of I-80 west or Des Moines on any of the signs).

Speaking of which, the connection from I-80/94 west to I-65 north doesn’t see much action (even less so with the likelihood of Gary Railcats Baseball being cancelled) outside of usage as a detour or a quick connect to 15th Avenue. The same can be said for the ramp from I-65 south to I-80/94 east.

Since the I-57/294 interchange opened I am sure the I-294SB to I-80WB ramp is hardly used as is the I-80EB to I-294NB ramp.

I-75 NB to I-675 SB on the northern end. I use that ramp often enough though to make the loop back to Saginaw but not very many other people do. If you wanted to go to I-675 most people going north would use exit 150 and most people going south would use exit 155.

I-75 NB to I-475 SB also on the northern end. I-475 doesn't have a ramp to connect SB I-475 to NB I-75 and I-75 doesn't have a ramp to connect SB I-75 to NB I-475 on the southern end. But the northern end doesn't get used much.

I don't think NB I-475 to SB I-75 on the northern end gets used much but it's a quicker way to get from the Clio Road exit on I-475 to the Pierson Road exit on I-75.

Out west, I'll nominate I-86 WB to I-84 EB.  Not many towns from that junction to SLC on I-84.  It would almost always be quicker to take I-15 south to any areas of population.

I was on the SB I-75 to NB I-675 ramp about an hour ago lol. When you are coming from M-81 to downtown Saginaw it's quicker to go that way rather than continuing on M-81 to SB M-13.

Those aren't real high numbers for I-475 either but that's a rather dead part of Flint. SB I-475 is also useful for going from SB I-75 to EB I-69.

That might be the least-used Interstate-Interstate movement in PA. There is no reasonable path where that is the fastest route. Maybe if a trucker is doing everything possible to maximize freeway use?

Very good example! The NYS Traffic Data Viewer shows:

I-390 SB to I-86 WB: 172
I-86 EB to I-390 NB: 111

I think that's the clear winner so far for an interstate-interstate connection.
My bet is that even I-86 to I-90 in PA is going to be higher than that just because it's a more populated area and a more heavily-used travel corridor.

The last one has no purpose. It saves 3 minutes to take PA 89. Maybe it gets marginal traffic to North east.

can't find traffic data on individual ramps in South Carolina but a candidate for a low total would be the I-26 EB/I-95 NB movements and reverse.

With 4-laned US 301 connecting the two north of the 26/95 interchange there is almost no need to make these movements.

I feel like I-57 south to I-55 north could be used by people in extreme southern Illinois going to St. Louis.
It would be about 10 minutes slower vs. IL-3 and IL-146 into Cape Girardeau to I-55.

I'm not saying any of those connections aren't used, but they have generally low traffic volumes compared to the other connections based on the way the highways approach each other. For instance, all the other connections at the I-55 / I-57 / US-60 interchange would have higher volumes than that particular movement. I didn't confirm any of these with actual AADT counts, but this is just largely assumptions based on the highway locations and population centers.

Going from immediately west of the US 60 intersection in Wickliffe to I-55 north of Exit 99, Google gives 1 hour 2 minutes (63.6 miles) via US 60, I-57, and I-55.  Via IL 3 it gives 55 minutes, 46.9 miles.  The interstate option might be better than dealing with slower drivers, farm equipment, and the possible revenue patrols on the Illinois side.

It sure seems like exit 1 has more traffic than that. What about exit 153 off I-75?

What's the AADT on the ramps at exit 2 and 2A on NB I-675? The first one is 5th and 6th Avenues and it leads to a pretty dead part of town for the most part and use to be the downtown exit before the Warren Avenue exit was built about 10 years ago. Exits 3 and 6 will be much higher and exit 1 probably a little busier but not much.

Exit #1 = AADT 272
Exit #2 = AADT 404
Exit #2A = AADT 722
Exit #3 = AADT 7508
Exit #6 = AADT 8833

It sure seems like exit 1 has more traffic than that. What about exit 153 off I-75?

AADT for Exit #1 is quite a bit larger on southbound I-675 than on northbound:  2282.
But, entering traffic from Lapeer/VetsMem onto southbound I-675 is really low:  79.

As for I-75 Exit #153...
NB = 1890
SB = 767

The area around exit 1 is pretty much light industrial along Vets and residential off of the side streets. For SB 675 off Vets its not a movement I take very often myself I live about 7 miles from there and I'm in that area pretty much every day. It'd be a quicker route to get to the Holland and Outer Drive area via I-75's exit 149 though.

Another one I wouldn't think is very busy but it would make sense if it was is I-675 SB to I-75 NB. The reason it could be busier and I use this ramp for this purpose is to get to exit 151 which is M-81 going towards the thumb area.

The M-46 interchange is currently under construction for the next two years so more people might be trying to avoid that interchange using M-81 as well. I have noticed the Michigan State Police patrolling this construction zone too.

I-675 SB to I-75 NB

AADT = 1223

But the reverse is 856.

There are some pretty low numbers on some of them. Exits 3 and 6 serve busier parts of the city/township as exit 3 leads to M-58 and larger populated areas and exit 6 is the mall area with everything that's usually around a mall area.

I wouldn't think EB Tittabawassee to NB I-675 would be too busy at exit 6.

In Arizona it has to be the ramp from I-10 W/B to I-17 S/B (very long and high flyover ramp that is completely redundant due to the freeway configuration of the area).

Major connection from I-10 from points east such as Albuquerque to I-17 South bound towards Phoenix.

Could theoretically be only 1 lane or a loop, but I wouldn’t imagine it’s an underused connection compared to a ramp such as I-10 East to I-17 South.

I could be wrong though, I don’t have the numbers.
There are faster ways to get from Albuquerque to Phoenix.

I misread the post, I was thinking I-40 and I-17, not I-10 and I-17. I-40 westbound to I-17 southbound has a flyover connection as well, though it's in Flagstaff, not Phoenix. I-10 runs through Phoenix.

But for the Phoenix to Albuquerque connection with I-40 and I-17, arterial routes may shave 5 or 10 minutes off for traffic bound to the central or east side, but the interstate is still the most efficient and likely preferred route for most.
