Are there other examples of pergolas in North America besides the ones built into the I-5/SR 2 (Golden State Freeway/Glendale Freeway) interchange in Los Angeles?

This example surfaced earlier today on the Freeways in Los Angeles Facebook group and it is the first American example of a pergola I can remember ever seeing, although this form of construction is used quite extensively in Spain, with many, many examples across multiple regions:

If I'm understanding the question and examples, that is how much of the interface between the I-5 main line and the Express Lanes is handled under the Convention Center in downtown Seattle, as well as the Alaskan Way Viaduct.
Or are you meaning for decoration only?

Just to thank you all for the examples supplied so far--it seems pergolas are more common in North America than I had thought, though perhaps not nearly as frequently encountered on a per-centerline-mile basis as in Spain.

I looked at I-5 under the Convention Center and SR 99 (I presume through the Battery Tunnel) and it seems the concept is structurally pretty similar, with deck lids in both cases supported by transverse stringers resting on walls. But the classic pergola (for which the term in Spanish is the clearly cognate
pérgola, a word that is also used to refer to pergolas in the gardening sense; I'm not sure what formal term, if any, is used in English) supports a crossing at extreme skew with stringers left exposed where they are not covered by the overhead facility.

I think it's an edge case. These are straddle bents and are another way to handle skew crossings. I suspect, though (not having seen the construction plans), that each leg has its own footing, whereas every pergola for which I have seen plans has had both sides of the "box" supported on a common footing.

Yup!
They are fairly common in the Netherlands.
This one is located on A4 between Amsterdam and The Hague, where the freeway crosses the high-speed rail line. Notice how it was built with a future expansion to 10 lanes in mind.

I've never heard that term before. I like it, though.
My first reaction was, "Those things are all over the place in Atlanta," but some of the ones that popped into my mind were actually covered, including four for the ramp braids at I-85 and Sugarloaf Parkway not far from my house. I think the largest one might be at the SPUI at Lenox and GA 400:

What about the structure on eastbound I-210 just before Santa Anita Avenue in Arcadia that holds the Metro-Link tracks? Would that be a pergola?
Incidentally, I didn't know that's what it's called.
If you're just talking about external support structures to prevent a pier from being plopped down in the middle of a main lane, these are all over the Metroplex.

The Philly area has several as well.. I276 over PA132, and I76 under the freight line between exits 348 & 347 are the obvious ones.

Nice example on CA 99 at Livingston, on a S-curve that takes the freeway under the UP (former SP) SJ Valley main line. It opened circa 1997, replacing one of the more tight & narrow 4-lane underpasses on 99.
