Airports with 360 degree orbital beltways

As a follow-up to my last post, I thought it would be interesting to list off the airports around the globe that are ringed by limited access expressways. Such a design has several benefits – the expressway can serve as a clear demarcation between the airport and other uses and the expressway can serve is a bit of a noise buffer.

On the less positive side, expanding an airport hemmed in by expressways can be more expensive as tunnels or heavy-duty bridges are necessary. A quick trip around the southern end of Atlanta’s airport on I-285 demonstrates this issue.

In some cases the beltway around the airport largely defines the airport boundaries, as in the case of Chicago, O’Hare, while in others, some elbow room is left for future expansion and/or development. In the end, it was my job to discern what constituted an orbital beltway around an airport and what did not. Obviously, limited access was one factor, but distance away from the existing airport was another – too far away is hardly an airport beltway.

So, here’s my list…which over time will likely grow as other highways are built or airports expand or are replaced. Any additions, corrections, or thoughts are most welcome.
