Airports in the US without access to a limited-access highway

[X99]

Rapid City Regional Airport only connects to the four-lane divided SD 44 at-grade expressway, but if traffic volumes ever warrant it (they probably won't), there's plenty of empty farmland to the north that could be used to run a freeway (or at least another expressway) to the airport. 44 between the airport and US 16 Bypass is too developed on the west end to convert it into a freeway, and although a freeway upgrade of the bypass between 44 and I-90 would be possible, I don't think anyone here wants that other than me.

This topic would work better if limited to major airports. It's practically a necessity for major airports like O'Hare and LAX. It's pretty irrelevant for the Bugtussle County Airports of the world. I live in Palm Springs and getting from I-10 to the airport is several miles and nowhere near direct. But highway access is unnecessary here, even though it's a moderately busy airport with several airlines and some international flights. It was also unnecessary when I lived in Norfolk, Madison, and Green Bay. The only place it would be nice is St Louis where only the East Terminal has direct access and even that is going to and coming from the city center on I-70. There might have been a bigger need for direct freeway access if Carl Icahn hadn't gutted TWA before selling its remnants off to American Airlines, but St Louis is not the airline traffic hub it was 25 years ago.

Agreed, but according to the OP, LAX does not have limited access connections (which it does).

Not Interstate direct access, but I-105 connects to Sepulveda Blvd. which connects to the terminal circulator road system.

Is that segment of Sepulveda Blvd. not a full freeway design?

[froggie]

^ No.  There's a traffic signal where the ramp from the westbound 105 meets northbound Sepulveda.

Also, depending on how you exit the main terminal area, there's a signal to go through to get back onto Sepulveda.

[Beltway]

No.  There's a traffic signal where the ramp from the westbound 105 meets northbound Sepulveda.

Was the argument made that it could be eliminated by restriping the road and merge area, rather than 3 lanes taking turns via a signal?

Also, depending on how you exit the main terminal area, there's a signal to go through to get back onto Sepulveda.

Center Way?  Looks like World Way has full grade separated connections.

[froggie]

^ I would think that traffic volumes on Sepulveda are too high to allow for restriping.  A further constriction is you only have 3 lanes through the runway tunnel and less than 700ft from the merge point to the tunnel.

Upper World Way has full grade separation.  Lower World Way doesn't, and Lower World Way is where you pick up arrivals from.

In the Continental-merged-with-United States, Key West is the longest distance for an airport classified as a "hub". Which is akin to calling the road in your local sub-development a "Super-2".

Two-and-a-half hours and 125 miles away to Florida's Turnpike.

Interestingly both levels of World Way at LAX also have signalized crosswalks (though there are many more on the lower level than the upper level): https://goo.gl/maps/WVGbCkq7WhabXstV9

The u-turns on the upper level are also signalized: https://goo.gl/maps/q2G7i6uNGZ8t1xkQ6, meaning even without the signal merging onto Sepulveda from the 105 it would be impossible to pick up someone at any terminal without going through a signal.

COS does not have direct access to a limited access highway.

The easiest way to get there from the south is to exit I-25 is to exit Academy Blvd (a signalized diamond interchange) then head east then north on Academy (freeway-ish with a 50 MPH speed limit and three folded diamond interchanges) to an interchange with Martin E Proby Pkwy. One must head east on Proby Pkwy, which is a 55 MPH expressway with two signalized intersections, an EB RIRO, and a non-signalized intersection to get to the terminal.

From the north, the best route is probably US 24 Bypass, which becomes a surface street just past Circle Dr, east to Powers, right on Powers (CO 21--possibly a freeway in the future) to Proby Pkwy.

Grand Forks airport in ND.

Arguably New Castle Airport in DE, US 202/13 but no direct access to I-95/295.

Atlantic City, Only connection is via county roads to 30/ACE/GSP

Fort Wayne International.

[Bickendan]

Airports in the US with partial access to a limited-access highway:
Portland International Airport (PDX) - NB exit and SB entrance off of I-205 only

I disagree, Airport Way has an at grade intersection with 82nd before you get to the airport proper.

Beat me to it.

Has anyone mentioned Yeager Airport in Charleston, WV?  (CRW)

It's about 2-and-a-half miles from I-64/77 via State Route 114, followed by 2-lane, wooded Airport Rd.  But this is expected since the airport is at the top of a mountain.  They are served by Spirit and a handful of commuter flights.

[MCRoads]

I'm surprised that OKC hasn't been mentioned yet. Interestingly, the access road is actually the intersecting road of a diamond interchange, while the road underneath is free-flowing!

Columbia (SC) Metropolitan Airport (CAE) is not served by a freeway, but the passenger terminal is served by an interchange off of an "Expressway"  that has at least three traffic signals and a few other at-grades.  Columbia Airport Expressway is/was proposed to be extended at both ends to directly connect to both I-26 and I-20, but it has hardly been discussed in the nearly 10 years that I have lived in the area.  For now, the easiest access to the airport from I-26 involves going through up to 6 signalized intersections via SC 302 (Airport Blvd) and Columbia Airport Expressway, or if coming from I-20 it's much worse as that involves at least 6 signals and a four-way stop via US 1, Ermine Rd., and Columbia Airport Expressway (Ermine Rd will likely be demolished if/when Columbia Airport Expressway is ever extended to I-20).

Neither of South Carolina’s two major coastal airports (MYR and CHS) have direct freeway access. Charleston is a few lights on International Parkway from I-526, while Myrtle Beach requires passing through multiple lights on Harrelson Blvd to reach US 17 - which is sort of a freeway there, but not really. If you want a true freeway, you have to keep going on George Bishop Parkway and US 501 to reach SC 31.

Monroe Regional (MLU) is 4 turns and several traffic lights away from I-20

Isllp - Long Island MacArthur Airport (ISP) Ronkonkoma, NY  Access to I-495 and NY27 via NY 454

Richmond International (RIC) has no direct freeway access. Airport Drive has some interchanges on the airport grounds but it also has at-grade intersections, including some within interchanges.

Norfolk International (ORF) also has no direct freeway access.
