Thought you meant auto.  Well High Bridge in NYC was built to carry water before it opened to pedestrians.

I get it's still traffic of a kind, but I-70 use to have one of Stapleton's runways over the top of it here in Denver.

I remember that, I think.  I-190 at O'Hare as well.  There's a runway across Central Avenue here in Wichita.  But yes, those are bridges designed to carry traffic.

Truss structure carrying two pipelines over the Puyallup River, near Orting, Washington (about an hour south of Seattle):

I think it was built in the 1930s. It was originally adjacent to the first McCutcheon bridge, before that bridge was rebuilt in the 1990s.

There are some dramatically large bridge structures to hold runway approach lighting at Seatac Airport, in Seattle:

They pass over the valleys north of the airport, as well as the WA-518 freeway.

Schiphol Airport near Amsterdam has two of these over the A4 freeway (Euroroute E19).  The southern taxiway has a bridge over A4, then the A4 tunnels under the main east-west runway and associated taxiways.  In this case, the reason this is unusual is that all of Schiphol is some 13 feet below sea level.  The name Schiphol means the same in English, "ship hole" (essentially a turning basin for the old long-abandoned inland seaport).

I-376 in Pittsburgh has a bridge over it whose purpose is to collect falling concrete from the crumbling arch bridge above it.

That one has since been removed with the complete replacement of the upper bridge.

At one point one such bridge, the Hegigio Gorge Pipeline Bridge in Papua New Guinea, held the World's highest bridge title. It has been since surpassed by no less than 6 Chinese expressway bridges. In fact it is still the only one of the top 10 highest bridges not to carry a freeway, and one of only 2 outside China (the other is in Mexico).

What is the one in Mexico?  I ask because Puente Baluarte carries a freeway—it just happens to be a two-lane freeway.
