Fun with highways: Bay Bridge construction

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.

Fun with Highways: I-85, I-75 and I-20 in Atlanta

It’s been a while since we’ve done one of these:

This is the interchange of I-85, I-75 and I-20 in Atlanta, GA. No personal significance, though I do like how the incredibly complex curved shapes are bounded by the very rectangular city streets.

Of course, the combination of curved forms and rectangular geometry is not too uncommon here at CatSynth.

Fun with Highways: Chinese Edition

Well, it has been a while since I have done a “fun with highways” post here at CatSynth, so why not visit some of the highways I traveled while in China?

Shanghai has a series of highways, most of which are designated with the letter “A” followed by a number:

During my trip, I became quite acquainted with the A11 (Huning Expressway) that connects Shanghai to Suzhou and beyond. However, one cannot really view either city from the A11. Nor can one really see the details of the delta region. It’s just a big highway traversing sprawling suburban development like one can see in many parts of the U.S.

By contrast, the A9 extends into the center of Shanghai as the Yan’an Elevated Road. Shanghai makes a distinction between “expressways” and “elevated roads”, though I don’t really see much difference.

The elevated roads are multi-lane freeways, and the Yan’an cuts right through the downtown of the city, closely paralleling the pedestrian thoroughfare Nanjing Road and People’s Square, before ending at The Bund along the river.

Essentially, it parallels a major part of my walking tour only a few blocks away.

Photographer Liao Yusheng has a fantastic series of architectural and landscape photos along the Yun’an Elevated Road, along with this description:

Yan’an is part of a sprawling elevated highway system in the heart of Shanghai that epitomizes the gung-ho mega public-works projects that are going on all over China at the moment. This is a six-lane highway that is literally jammed into the middle of a densely packed modern city. Hundreds of thousands of families were displaced and hundreds of millions of dollars were spent to make this happen. In forcing this monstrosity onto an already fully-developed (yet still evolving) megalopolis, Shanghai has created a conduit with which to examine the multilayered texture that makes up this city.

I only discovered his work in preparing this article, but it was a great find and reminds me of my own urban and architectural photography. I encourage readers to check it out!

The story does remind me of the highway development in New York City in the 1950s and 1960s, where entire neighborhoods were demolished to build, among others, the Cross Bronx and Bruckner Expressways. Somehow, we often end up back there.

I did also find that China has it’s own highway enthusiasts, including the blogger Wang Jian Shuo.

Fun with Highways: The Alemany Maze

We return to a favorite topic here at CatSynth with a highway interchange that we know quite well.

The Alemany Maze is the large interchange in southern San Francisco between US 101 and Interstate 280. It derives it’s name from Alemany Boulevard, which runs parallel to 280.

In the upper-left corner of the interchange is a large lot that is home to the Alemany Farmers Market, which has been operating at this location since 1947. I wish it wasn’t only on Saturdays (indeed, it would be great if it operated on a weekday evening to pick up fresh ingredients for dinner on the way home from work). Beyond the lot is 5lowershop (pronounced “flower shop”), where I performed two years ago at the headphone festival. I will be performing there again in October.

The section of the I-280 north of the interchange is the last double-decker freeway in the Bay Area.

In the years since the infamous collapse of the I-880 Cypress Freeway in the 1989 earthquake, the other double-decker freeways have been torn down, leaving only this far less controversial section of I-280. You can read more in this article.

Whenever I drive to work (sometimes I take BART), I pass through this interchange on I-280. Besides it’s largeness and the annoyance of having to change lanes just to up against the freeways and the ramps.

Indeed, the houses along Boutwell St lie in between 101 and the ramp to 280, which seems like a somewhat surreal place to live. Similarly, I see these and other houses on the top of the hill on Charter Oak Avenue (north of 280) when driving south:

The houses on Charter Oak are actually on a steep hillside, so are somewhat sheltered from the freeway, though they also have a rather direct view of the double-decker section.

All these houses are part of the Bayview District of San Francisco (also known as the Bayview-Hunters Point District), which extends east from 101 to the bay. I can only imagine that these house all pre-dated the construction of I-280, which was built in the late 1960s. More information on the history of I-280 can be found at California Highways.


Primary Highways: Montana and South Dakota

Well, this long process is nearly at it’s end. And this time, we really mean it, there are only two states left, Montana and South Dakota. I had an opportunity to visit both as a kid in 1988. It was only as I prepared to write this article that I realized this was twenty years ago!

We came into Montana at night on I-94, which we previously mentioned in this series when we visited Indiana and Detroit. The night sky in Montana is an amazing experience, as is the complete darkness if one stops the car and turns out the lights. A little eerie, actually. I grew up the suburbs north of New York City, so such clear and dark nights were a new experience.

I-94 ends quietly at junction with I-90 near Billings, the largest city in Montana. I don’t remember much about it.

We did visit Yellowstone National park, which is mostly in Wyoming. But the northern entrance, featuring the Roosevelt Arch, is in Montana:

We discussed Yellowstone in more detail when we wrote about Wyoming. But I didn’t mention the fact that I was there during the massive fires of 1988, that burned about one third of the park. The smoke and the various closures certainly colored my visit. I do need to go back again and experience Yellowstone as an adult and without the fires.

From Yellowstone, we traveled north and east, stopping in the town of Butte. Though quite small, I recall it looking rather large as one approached from the east at night on I-90. We at CatSynth would not deign to make jokes about the town’s name.

Ultimately, we headed north on US 93 to reach Glacier National Park. This was an altogether different experience from Yellowstone. Not only were the skies clear, but landscape was more the standard forests and lakes and mountains one associates with Rockies:

Among the striking features of Glacier Park are its lakes, such as St. Mary Lake (pictured here) and Lake McDonald. Lake McDonald in particular is quite deep, as it is formed from a valley between mountains, though not as deep as Crater Lake in Oregon. The park does of course have Glaciers, but they have been retreating quite dramatically, victims of climate change.


Our trip back from Montana took us through South Dakota on I-90. The main feature of I-90 in South Dakota were the frequent billboards advertising Wall Drug, which we of course did have to stop at, after having fun with the concept for the preceding hours. We did of course visit the more monumental attractions, including the dueling carved mountains of Crazy Horse and Mount Rushmore.

We ultimately continued east on I-90 to Chicago, the hometown of the likely winner at the end of this long contest.


Primary Highways: Oregon

Our series returns to the west coast, and to a state I know from personal experience. I have traveled through the western part of Oregon multiple times. It is a state that at first glance has much in common with northern California, politically and geographically, but has its own unique characteristics.

Traveling north on I-5, one crosses an arbitrary line the separates the spectacular landscape of far-northern California from the spectacular landscape of southwestern Oregon. The highway weaves through the mountains and valleys of the Cascade Range, including numerous volcanic (or formerly volcanic) peaks.

At the town of Medford, one can continue north, or take a detour east on state highway 62 to Crater Lake. Crater Lake fills a caldera in the Cascade Range, and is the deepest lake the United States. It's circular shape is quite distinctive, as are its internal landmarks, including Wizard Island (the pointy island to one side of the lake), the “Old Man of the Lake“, and several volcanic formations. I had the opportunity to visit Crater Lake many years ago.

More recently, I traveled the other route from Medford, on I-5 north to Portland, while I was on tour last October.

We experienced Portland's famously variable weather. Fortunately, many of the city's attractions are indoors. This includes Powell's Books. I could have spent the whole day in the Pearl Room, which contained the art and architecture offerings, as well as their extensive rare book collection.

Portland also has abundant public art. Across from Powell's is this “brush,” a noted landmark:

This building brings to mind the city's nickname, Rose City.

These are only a few of the photos I took while on tour. Please visit the original article for more images, including the intriguing “recursive elephant” sculpture (and the hidden cat).

Portland is someplace I could see living, and indeed the idea crossed my mind during my period of unemployment last year. Ironically, it was en route to Portland that I took the fateful phone call that led to my current job and new life in San Francisco.

We also performed in the coastal town of Astoria, which can be reached by traversing the coast range or traveling along the Columbia River on US 30. This is actually the western end of US 30, which starts at a junction with our friend US 101.

Astoria was cool and rainy and very green, as one would expect along the northern Pacific coast. The people we met there were also very welcoming to a group of Bay Area musicians playing weird experimental music. Again, you can read more about our visit at the original tour article.

I have never been to the eastern part of Oregon, which is a very different place altogether. I am quite intrigued by the descriptions of part of eastern Oregon as a desert landscape. But it seems like one has to be very motivated to visit, as it is far less populated and less accessible via major highways. The east-west divide also seems to extend to politics, with western Oregon being more liberal in the “northern California” sense, and eastern Oregon being more conservative. I wonder how this divide is going to play, at least in the media, given the patterns of this election…
