I was just checking out Google Maps, looking at the old layout of Denver's (now decommissioned) Stapleton Airport. On the map, Interstate 70 completely bisects one of the runways right in its midsection.
I'm fairly confident this wasn't the case when the airport was operational. How was the highway routed back in the good ol' days of Stapleton?

If I remember correctly, the structural strength of the bridges (there were two, one for Runway 35L/17R and its parallel taxiway and the second for the taxiway to Runway 35R/17L) did not permit 747s to use either of the two runways. 747s used runway 26L/8R if I remember correctly.

There are several examples of runways that go over freeways and city streets:
At LAX, Sepulveda Blvd tunnels underneath the southern runways. That's an experience - a fully loaded jumbo jet lumbering for take-off and vibrating the whole tunnel!!
At BFL, both runway 30R and the adjoining taxiway cross over Seventh Standard Road.
At the Boeing assembly plant, the planes must cross over a road on an overpass to reach the final assembly point. Is this the paint shop? Someone in the know help me with this one - I've only seen pictures of it!!
At ORD, several taxiways cross directly over the entrance road, leading to 31L (?). Whether or not they will all be kept is unknown to me.
At ATL, the new runway (10/28) goes under the interstate highway.
Are there any others?

I-70 runs along the left side of this a.net Stapleton photo. A dirt outline of where runway 17R/35L sat can be seen running left to right in the center of the picture. The threshold of runway 35R was located roughly where the left of the two newer white roofed buildings sits.

Not just major international airports either, even though it seems quite the expensive alternative when you're talking a GA field..
My new "home" tiny little Greene County Regional (I19) here near Dayton has a county road going under it's sole runway, because somehow they found it more economical to tunnel the roadway than to put a little meander in the roadway when they lengthened the runway. http://i19airport.com/tunnel/index.shtml
Likewise PA-885 goes under the main runway at Pittsburgh's AGC.

I specifically remember seeing 747s from CO, Pan Am, and Flying Tigers taxiing over I-70. So I think they were cleared to use 35R/17L.

A 747 is alot less stress on a structure while taxiing than landing (even the best "greaser" is a pretty heavy hit when the plane weighs that much... and harmonic motions on bridge structures are not a good thing.)
They may have been permitted taxiing across the structure, just not allowed using it for actual flight operations.
The second photo doesn't reflect the additional tunnel area for the taxiways linking the terminals with 35R/17L...If I recall when those tunnels came down in 1995, they came down a little easier than they should have....Will have to try and find the old story of it.
