Longest distance between interstate junctions

[wriddle082]

Wondering what the longest distance is along an interstate between junctions of other interstates.  I'm thinking it's either I-5 between I-505 at Dunnigan, CA and I-105 in Eugene, OR, or I-90 between I-82 in Ellensburg, WA and I-15 in Butte, MT.  Anything out there longer than either of those?

I-94 East of its west end?  I-194 in Bismarck is unsigned...

According to Wikipedia, this stretch would be 598.7 miles over which the only Interstate sign you would see is an I-94 sign.

I-80 between I-580 in Reno and I-215 in SLC is 512 miles, longer than both of them.

Almost nothing very long on the east coast. Wonder what the longest is.

It would be I-95 in Maine at about 200 miles between I-295 and the Canadian border.

A top ten would be interesting here.

I-20 from I-10 East?   420.5 miles.
I-10 between I-19 and I-25?   293.2 miles.
I-40 between I-17 and I-25?   323.9 miles.
I-70 west of Denver?  The next post says 501 miles.
I-80 from Cheyenne to I-84?  428.9 miles.
I-10 from I-20 to I-410 in San Antonio?  386 miles.
I-90 from Rapid City to Sioux Falls?  338.7 miles.
I-25 from Albuquerque to Denver?   434.4 miles.
I-70 from Denver to Salina?  416.7 miles.

[US 89]

I-70 has 501 miles between I-15 at Cove Fort and I-76 near Denver.

Does I-10 hit anything besides I-19? I took the bus from LA to Austin (via San Antonio) and don't remember actually seeing a junction with I-8, I-17, I-20, or I-25. It looks like the route of I-10 must get close to all of these, but I certainly missed all of the I-junctions. It's a long way from Tuscon to Las Cruces and event further Van Horn and Fort Stockton.

I-395 in Bangor.

You must of been sleeping, it interchanges all of them.

Don't forget I-395 in Bangor. It's 122 miles from there to NB.

It appears the longest east coast distance may actually be in Florida...

On I-95, there's about 236 miles of interstate-free interchanges between I-4 near Daytona Beach and I-595 in Fort Lauderdale.

What about I-75 between I-595 and I-275 in Florida?

Longest in the northeast is probably I-87 between I-90 and the Canadian border (175 miles).

That appears to be just slightly shorter, at around 210 miles.

[Ketchup99]

The longest in the Northeast might actually be I-80 in Pennsylvania. From exit 19 (I-79) to exit 212 (I-180), there's no interstate junction - a distance of 193 miles. I-99 is served at exit 161, but it technically terminates just south of the interchange, meaning it doesn't count. If not for the tiny I-180, the next interstate would be I-81 at exit 260 - a whopping 241 miles.

In Florida, I-10 runs 283 miles without interstate junctions between I-75 in Lake City and I-110 in Pensacola.

It intersects I-17, I-8, I-19, I-25, and I-20, in order from west to east.

In Michigan, it's I-75 between Saginaw and Canada (240 miles).

[sprjus4]

Virginia:
I-64 between I-295 west of Richmond and I-81 near Staunton - 87 miles

North Carolina:
I-40 between I-240 east of Asheville and I-77 near Statesville - 99 miles

[mgk920]

For Wisconsin, it would be I-94 between I-90 (Tomah Interchange) and the Minnesota state line, 146.  Adding the short continuation to I-494/694 in Minnesota, it would be just under 160.

I-86 from the western terminus to I-390 comes close, at about 150 miles.

[Roadgeekteen]

For Massachusetts, probably I-91 between I-90 and I-89.

[Ben114]

For Massachusetts, probably I-91 between I-90 and I-89.

Seems about right, at 113 miles. Second would probably I-90 between I-91 and I-787 at 83 miles.

I was certainly TRYING to sleep some of the way from El Paso to San Antonio, but it is possible that we weren't on I-10 the whole way. I was trying to be very much awake between Phoenix and El Paso (daytime leg) because I had never been in New Mexico before. I was expecting Wily Coyote and Roadrunner and some unusual rock formations to show up. Nothing like that on I-10. On I-10 Eastern Arizona, New Mexico, and West Texas all pretty much look the same. If any of that exists, it's not on I-10.
