How many Airports are over roads?

Recommended Posts

Pittsburgh's original "major" airport (1931-1953 the ones previous to this weren't much more then landing strips) is the Allegheny Airport it is still used today much like every other major city the old "major" airports serve as today's commuter/private plane/ corporate jet airports.

Anyways my question is how many airports out there have tunnels for roads to go underneath them? I wouldn't think Pittsburgh is the ONLY city to have a major or once major airport to have that distinction.

Here is Pittsburgh's Allegheny Airport road tunnel over its main runway:

I'm thinking Chicago has a taxi lane over a road, but it may be a private road.

These are actually really common.

IAH in Houston has two. Sky Harbor in Phoenix has at least one.

Then, of course, there's the famous CA 1 tunnel under LAX. It's been used in quite a few movies.

I'm pretty sure the access road for DFW airport (Dallas-Ft. Worth, Texas), International Parkway, tunnels under one or more taxiways.

Chicago's taxiway goes right over a major freeway.

The Addison Airport Toll Tunnel (AATT)

The AATT opened to traffic in February 1999. This two-lane tunnel crossing under the Addison Airport is approximately 1,600 feet in length, with a total roadway length of 3,700 feet.

The tunnel expands traffic capacity and eases congestion in the northern sector of Dallas and Addison by providing an east-west route between the DNT and IH-35E under the Addison Airport runway. It provides motorists a through passage on Keller Springs Road, which once ended on either side of Addison Airport, as an alternate to Belt Line Road on Trinity Mills Road.

Description: Two-lane tunnel, approximately 1,600 feet in length, with a total roadway length of 3,700 feet.

International Parkway goes under DFW Airport taxiways at the north and south ends of the airport. Very cool to watch the planes roll over as you drive by.

Here is a picture of the construction of the fifth runway at Hartsfield-Jackson International Airport in Atlanta. As you can see, it will span an interstate. Interstate 285 will flow under the runway. Amazing.

Here is a picture:

The dirt swath is where the runway will be. At 9000ft there will be some pretty big jets on there.

I will be curious to see landings on this runway.
