Roads Underneath Airport Runways and/or Taxiways

[jakeroot]

Doubt it counts, but it's worth mentioning.

Tacoma Narrows Airport (TIW) has a tunnel beneath an extension of the land north of the runway (Stone Dr NW), but it does not cross beneath a taxiway or runway.

It opened in 2009 to protect road users from planes either landing short, or running off the runway.

To a degree, such is similar to the fore-mentioned PHL's Runway 8-26 example I posted earlier.  That said, I would say such counts.

Columbus John Glenn - terminal entrance/exit goes under a taxiway

As well as Sawyer Rd (I'll go verify this, tonight)

Sawyer crosses under three times, I believe.

Charlotte Douglas Airport doesn't have any road tunnels, but it has two railroad tunnels under the taxiways leading to the west runway.

Here in Wichita, Central Avenue goes under the Beechcraft factory runway.

This was mentioned in passing, but I will mention it again -- https://tinyurl.com/y3mt53ep

I-564, a 6-lane Interstate highway, under a Naval Station Norfolk Chambers Field runway.

Going international again, in Gibraltar there's a surface crossing of a road over an airport runway, with gates blocking passage when planes are landing.  Set to be bypassed in the future.

There are several taxiway crossings over the Zentralallee at the Flughafen München (Munich Airport)

(Whew, all caught up.) See tables in first post.

Here's one from the "former" category:

DEN (Old Stapleton Airport) -- at least one runway/taxiway used to cross over I-70 just east of I-270.

Wasn't mentioned more because it was already on the OP's list from the get-go.

I-564, a 6-lane Interstate highway, under the a Naval Station Norfolk Chambers Field runway.

FTFY.  There's only one runway at Chambers.

Given the length of that list I felt it was "in passing", and I wanted to highlight it and post an aerial view.

I could see that before I posted the link. 

Writing "under a runway" doesn't mean that there need to be more than one.

Not sure it counts, but...

YUL - Pierre-Elloitt-Trudeau International Airport, Montreal, QC, Canada - Autoroute 13 - Autoroute 13 goes in a tunnel just at the end of 06R-24L runway.

SR 526 dips under a taxiway at the Boeing assembly plant in Everett, WA, which is attached to Paine Field (PAE). Basically every Boeing widebody ever made has crossed over the freeway, which was built for the original 747 portion of the factory.

I took the Boeing plant tour, and one of the platitudes they gave to the the tour was that this bridge is the only privately-owned vehicle bridge over a Washington State Highway.  I have to dispute that if railroad bridges count, and if the bridge near the Enumclaw Weyerhaeuser mill between it and the scales counts.

Where was this mill, and where was/is the bridge? I'm doing some digging on that old mill in Enumclaw, but I'm not seeing many results (besides that it closed in 2003, and that websites weren't as comprehensive back then).

Since the mill is closed, it's possible the bridge is now owned by the state, and the tour operator could get by on a technicality.

Cheers. I totally forgot about that overpass, despite having driven 410 for...I dunno, my whole life. I had wondered what it was for.

Last time I drove through the area (February), there was a WSP officer sitting just on the other side of that bridge doing something. Not radar apparently, as I passed him going well over the limit! Now I have two reasons to remember that bridge.

In Spain, M-111 crosses right below Adolfo Suarez Madrid Barajas airport (MAD).

[formulanone]

I now got MAD.

Updated table.

In Germany, the A3 autobahn passes under two taxiways at Flughafen Frankfurt am Main (FRA).
Also, the B433 passes under a main runway and taxiway at Flughafen Hamburg (HAM) and the A111 autobahn passes under the thresholds of the two main runways at Flughafen Berlin-Tegel (TXL).

There are likely others.

In the UK, the A79 used to cross the runway at Prestwick Airport on the level, but was rerouted around it a few decades ago. You can still faintly see the route on aerial images.

LAS McCarran International Airport (Las Vegas) Paradise Drive Under runway 7R-25L

Minor nitpicks:

It's Paradise *Road*, not drive. (It's commonly known as the "airport connector" or "airport tunnel" in this area.)

Also, it goes under both of the airport's east/west runways. (Formerly designated 7R-25L and 7L-25R, but both designations were changed to "8-26" in 2017, due to shifting of the Earth's magnetic poles. Google Maps' satellite imagery doesn't seem reflect this as of this post, but Apple Maps imagery surprisingly did.)
