Bridges that were designed to carry no traffic

Thought you meant auto.  Well High Bridge in NYC was built to carry water before it opened to pedestrians.
Every day is a winding road, you just got to get used to it.

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).
Supporter of the construction of several running gags, including I-366 with a speed limit of 85 mph (137 km/h) and the Hypotenuse.

Please note that I may mention "invalid" FM channels, i.e. ending in an even number or down to 87.5. These are valid in Europe.

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

Well, I meant it is one of the only two of the 10 highest bridges overall (i.e. carrying anything) to be outside China, the other, as you said, is the Baluarte bridge.

That bridge has been removed and a new bridge has been built in the same spot. The new bridge is about 4 years old now.

Is that one still there?  I've heard it was removed.

The Watchung Reserve in NJ has wildlife bridges over I-78.

Hagerstown Airport runway goes over US 11 but not sure that counts?

As I am the OP, I'll say that animals and airplanes both count as "traffic".

Near Franklin Furnace, OH, there is a cable suspension pipeline bridge over the Ohio River, maybe a mile or so downstream from the Greenup Locks and Dam.  It can be seen from US 52 here https://goo.gl/maps/pZj4wqNanJ7ap6XH8 and can also be seen from KY 3116 (Old US 23) (no GSV).  I want to say it's a natural gas pipeline but it could be petroleum.  Been around for as long as I can remember.

Since my previous example has been demolished, I'll come up with a coal-carrying viaduct over US 83 near Flkirk ND.

I believe it has also been demolished but there was a coal bridge over PA 88 and the Mon River near Fredericktown

In Plattsmouth, Nebraska north of the toll bridge and the BNSF bridge is a pipeline suspension bridge at the Missouri River.

What bridges were built for reasons other than carrying traffic of any kind–not pedestrian, rail, vehicle, or otherwise?

Years ago, there was a coal conveyor system that crossed WV-93 in Bismarck that carried coal from the mine located north of WV-93 to Dominion Virginia Power's large coal-fired Mount Storm Generating Station.  I presume that the supply of coal that could be recovered from the mine at the other end of the conveyor ran out, and so the conveyor was shut-down and dismantled (this was years before ADHS Corridor H was constructed in this area).

There is a coal conveyor system in Utah's Wasatch Plateau that begins at the Skyline Mine and crosses SR 264 and SR 96 on its way to a railroad terminal just north of Clear Creek.

This can be one of them since it's cut off and a bridge replacement here would be a waste.

Google Street View from one of the (now cut off) side roads seems to imply that the former crossing was at-grade, and there was never a bridge there in the first place.

There is a bridge at that crossing. It goes over a creek. Thought I put the right coordinates, but it's this.
