This afternoon we at CatSynth avoid our responsibilities by presenting another highway interchange.

This is the so-called “Orange Crush” interchange in Orange County, CA, where I-5 and state highways CA 22 and CA 57 meet.  You can see how the three freeways converge in this USGS map:

I actually got to know this interchange quite well during my recent NAMM trip, and ended up at one point or another on each of the highways.

There is actually an ulterior motive in doing a highway post today.  I am planning on doing a few posts on the intersection of art and highways (no pun intended).  While I have collected a few examples myself, I would welcome suggestions from readers.

Reader Beth @ 990 Square recommended that we check out “The Mixing Bowl” on the Washington D.C. Beltway. Here it is:

The Springfield Interchange (as it is more formally known), is in northern Virginia and connects I-95 coming from the south to the beltway (I-495, left to right in the image) and I-395 north to downtown Washington, D.C. Part of the reason this interchange looks as complex as it does is that it was recently rebuilt, and contains the “ghosts” of the old interchange. Consider the following diagram:

The blue lines are the current interchange, while the red lines represent the pre-construction roadways. As one can see, several of the “red” pieces are still visible, such as the loop and ramps in the upper-right quadrant.

It seems the construction is not completely done, particularly along the beltway where there is still a lot of work going on. Or at least that was the case when I traveled through the interchange late on a Sunday night this past summer and got stuck for several hours.

Returning to San Francisco from New York often involves a highway trip to JFK Airport, and there is one spot along the Van Wyck Expressway (I-678) that is almost always guaranteed to come to standstill, the Kew Gardens Interchange:

The Van Wyck Expressway runs vertically in this picture, from the center top to the center bottom.  The Grand Central Parkway runs from the upper left to the center right.  The Jackie Robinson Parkway runs from the lower left to the interchange where it ends at the Grand Central Parkway.  The Union Turnpike runs along either side of the parkway.  Finally, the main surface thoroughfare through Queens, Queens Boulevard (NY 25) is in the lower left corner.

One doesn’t really see the complexity of this interchange from the road, just a series of exits in quick succession (or not so quick when one is barely moving), and in fact that it seems like the Van Wyck is merging into another, narrower road at the end, before the reassuring signs that one is still on the right road to the airport. It often seems like many of the larger highways in New York are really stitched together from older, smaller, highways.

This interchange was featured on Empire State Roads, with more information and images.

I have been on the parkways as well of course.  The Jackie Robinson Parkway winds its way narrowly towards Brookyln through parks and near several cemeteries.  I have relatives who reside in at least one of them.

Another piece from Performa: A Ballad of Accounting 2009: Composition for Cello and Brooklyn Queens Expressway, a composition by Alex Waterman with a 16-millimeter film by Elizabeth Wendelbo. I was quite interested to see this piece, given that it combines experimental music, art and highways, three of our interests here at CatSynth!

Waterman lived near the Brooklyn Queens Expressway, or BQE, and was inspired by the sounds of the highway as well as its history. It was part of Robert Moses’ master design for the city’s highways, and winds its way through a narrow corridor in densely packed areas of eastern Brooklyn and Queens. (See this article for more info.) Waterman often walked under the highway, listening to sounds and in particular the harmonics. The piece includes live cello performances near and under the highway, with microphones in the resonant chamber of the cello, as a way of modifying and eradicating the noise of the highway, as if “the cello was eating the highway.”

The video opens along the BQE, along the side, underneath, and riding on the surface, interspersed with images of Waterman carrying or playing his cello near the elevated structures. The music featured long notes set against filtered highway noises. There were lots of drones, often featuring noisy timbres or harmonics, but sometimes more familiar minor tonalities. The visuals included architectural close-ups of the elevated structures – hardly considered among the more picturesque in the city, but still quite interesting. I noticed exit signs for Metropolitan Avenue appearing a few times. One moment that particularly got my attention was a forlorn drainpipe. One could imagine the metallic resonances here, and indeed the sound became more electronic, reminding me a bit of early Xenakis. I also heard sounds that reminded me of more modern granular synthesis. There were also sharp departures from the drones, with very pointed “crackling sounds”, appropriate as the video began to feature rain and water dripping from the pipe.

There is a permanent installation of the piece near Calistoga, CA. I am curious to see it sometime after I return home.

The Bay Bridge has been closed over the Labor Day weekend for a major engineering feat. As part of the replacement of the eastern span, engineers actually cut out a small section near Yerba Buena Island, and actually wheeled in a new section of bridge. This allows the old doomed bridge to be used while the new one is connected up to the island.

Looking towards Oakland from Yerba Buena island, this is what things looked like before the cut- and-replace operation:

You can see a lot more time-lapsed photos and different angles at the official website for the project. They also posted some photos that better illustrate the move itself at Twitter:

Note that this does not really affect the western half of the bridge near on the San Francisco side, which is what we usually show in our Bay Bridge posts and photos at CatSynth. Except of course that it is closed.

And it looks like the closure could be a little bit longer than excepted. There was a serious crack found in one of the metal supports, so now they are working to repair that before opening. It’s just another reminder of why we want to replace the whole eastern span, hopefully before the next big earthquake. Fortunately, the closure doesn’t affect us at CatSynth all that much.
