Interstates that are entirely elevated

[HandsomeRob]

I drove down I-794 today, and noticed that every single yard of it is elevated. 794 is three and a half miles long - are there any longer interstates that never touch the ground?

Damn. I-910 touches the ground at the former toll plaza.

California's Interstate 380 MAY be entirely elevated...but not sure about the 1/2 mile immediately east of 280.  The old, now demolished Interstate 480 almost counted, but for its terminus at Broadway.

Which wasn't part of I-480, since the freeway was going to continue along the waterfront.

Wasn't there a period where the 480 extension to 101 had already been canceled, but it was still an interstate?  Something like 1967-1968.

In that case, would Broadway have been the terminus for I-480?

(The official California definition of Route 480 doesn't help as it always included the unbuilt segment to the Presidio)

I'm sure the twin spurs off I-275 in Tampa (I-175 and I-375) count.

I'm sure you're not sure.

Unsigned I-345 In Dallas, TX, but it's only 1.8 miles

I'm sure the twin spurs off I-275 in Tampa (I-175 and I-375) count.

Both of those spend a significant portion of their length on the ground.

How about Interstates that, if actually constructed, would have been entirely elevated?  My nomination - the cancelled I-695 "Inner Belt" in Boston.

that moon interstate that keeps floating around would have to be at least mostly elevated.

At least some of the plans would have had depressed portions: http://www.bostonroads.com/roads/inner-belt/

I-440 east of Little Rock is elevated for a significant portion, but I'm sure it's not all of it.

Correct...not all of it.

I take it back, then.

I just remembered I-395 leading into downtown Baltimore, which is elevated until you touch down near the Camden Yards baseball stadium.

DC's I-695 is entirely elevated except for a few portions near the 11th Street Bridge.

There is a tiny piece of I-794 that touches the ground inside of the Marquette interchange, but I don't know if anyone would count that against it.

I-165 in AL is completely elevated, too.

Future I-49 from Raceland to the old toll plaza will be approaching 50 miles.

I-310 (mm4?) to I-10 west to I-55 north around mm23 is about 37 miles of continuously elevated interstate.

[triplemultiplex]

I-794 used to be all elevated prior to the Marquette Interchange rebuild.  Now there's a short segment in direct contact with the earth.

[froggie]

I-165 in AL is completely elevated, too.

For most intents, yes, but it does touch down before its southern end.

[formulanone]

Pretty sure I-395 is entirely elevated. I-195 has a longer elevated portion, but it seems to hit ground level between the two Intracoastal Waterway spans, and at its eastern terminus with Alton Road.

"To I-90", Illinois

[CNGL-Leudimin]

Which is technically I-90

Ooh!  Let's drag this thread out to twelve pages with Interstates that aren't entirely elevated!  My nomination: I-35.
