I-5 Bridge, Santiam River



View Larger Map

Today's fun bridge adventure takes us south out of Portland, to the I-5 bridge over the Santiam River. It's not a terribly interesting bridge (ok, pair of bridges), just a big modern concrete job. Note that although there's a photo of the bridge on Wikimedia, nobody's ever bothered writing a proper Wikipedia article about it, which tells you something when you consider all the weird things that do merit their own Wikipedia articles. I only bothered with this bridge because I happened to stop at the adjacent Santiam Rest Area, and I noticed there was a bridge right there, and I figured I ought to take some photos of it, and here they are.

You will not be completely surprised to learn that the previous bridge on the site, from the highway's previous career as US 99E, was far more interesting, a classic Conde McCullough-style arch bridge. This is probably where the scalloped sorta-arch motif on the underside of the current bridge comes from. There's another photo of the old bridge on Flickr.

It turns out that the old bridge has a surviving sibling nearby. The Jacob Conser Bridge carries Oregon Highway 164 over the Santiam River at Jefferson, OR, and you'll note that it looks similar but not quite identical to the lost bridge. The state highway department liked to do variations on a theme back then, trying to make each bridge just a little distinctive. BridgeHunter credits the bridge to Glenn S. Paxson, McCullough's successor as State Bridge Engineer. Who, believe it or not, is also "credited" with Portland's unlovely Marquam Bridge. No, really, he is.

(I should point out that I'm not actually expanding the ongoing bridge project to Santiam River bridges generally. If I'm in the area again I might go check out the one in Jefferson, but I'm not promising anything. I'm also not expanding the city and state park project to cover highway rest areas, because that would be creepy. Eew.)

Jefferson Street Property expedition


View Larger Map

Today's thrilling adventure takes us to yet another (deservedly) obscure city park, one the city simply calls the Jefferson Street Property. Similar to the nearby Munger Property, it's a chunk of steep ivy-choked hillside overlooking US 26, just west of the Vista Tunnels. It isn't much of an urban crown jewel or anything, but I had a longstanding todo item about it, so I'm covering it purely for the sake of completeness.

Like many obscure city parks, the main useful piece of information about it on the interwebs comes from the city's Vegetation Unit Survey, which includes a map and a vegetation report. The report breaks the park down into two areas: A downslope level of primarily deciduous trees, and an upslope area of mostly douglas fir trees. And ivy. The report gives the douglas fir part of the park a 100% for non-native ground cover, and notes ominously that "The ivy infestation is complete." Yikes. And furthermore, the city's 2010 Natural Areas Restoration Plan rates the place as a "Low" on "Natural Resource Function and Value", which appears to be a longwinded term for "importance". So I think it's a safe bet that this park's going to remain 100% ivy for the immediate future.

The Munger Property vegetation map covers a wider area and puts this park in context, and based on this I'm not 100% sure I've got the park itself in the above photo. Which is always a problem when a park looks exactly like the non-park areas around it. It's either at the far left of the photo, or just outside of the frame, off to the left. If this isn't quite the right place, rest assured that the right place looks exactly like this, and I'm not inclined to go burn more gas just to take another crappy camera phone photo of anonymous trees.

Meanwhile, PortlandMaps knows the park as property ID R128449. Curiously (if you care about this sort of thing), the piece of land between this park and the big chunk of Munger Property to the south (ID R326836) is owned by the city too, but falls under the city property manager instead of the parks bureau. Don't ask me why, because I don't know. You could always call the city as an irate taxpayer demanding answers, if you're so inclined. I don't really feel like doing that that myself, but don't let that stop you. And if you do, and they give you a useful answer, feel free to post a comment here and let us all know what you found out. Really I think it would be more fun to just dream up elaborate conspiracy theories, like they're keeping it extra low profile because that's where the entrance to the lizard aliens' secret underground lab is located. I was going to say Batcave first, but the lack of Batmobile or other vehicular access makes that unlikely.

So at this point you might be thinking to yourself, "Hey, this place sounds friggin' awesome, I can't wait to go check it out, maybe bring a picnic, maybe plan a wedding there", etc., and you just need directions on how to get there. As far as I can tell the answer is "you can't". Despite the name, there's no Jefferson Street this far west. You might have been able to drive to the park before Sunset got the freeway treatment back in the 60's or so. You might even have been able to drive here until MAX construction removed part of Jefferson St. in the mid-1990s, although I'm not sure the street extended this far at that point. But it would've been a moot point anyway since the city only bought the land in 1995 (possibly in connection with the MAX project). And, unlike the Munger Property, you also can't get there from the West Hills side. Unless you buy one of the houses that back up to the park, I mean, which is yet another thing I'm not quite willing to do for the sake of a blog post. The vegetation summary report mentioned something about parking on the Jefferson St. freeway offramp, but you really don't want to do that unless you're in a large official-looking vehicle with flashing yellow caution lights on it, and probably not even then.

So a word of advice to those of you with blogs of your own. If you have an ongoing project or topic you write about regularly, and you feel you need to give it a really comprehensive treatment and cover things for the sake of completeness, eventually you're going to end up writing about stuff like this park here. You know it's useless and pointless and silly to write about it, but you can't not do it, because it's within the scope of your project, and them's the rules. And there's certainly no shortage of restaurant or band or movie equivalents to this place. So consider yourself warned, or whatever.

telephone pole, se 9th & madison

A small photoset about decaying concert posters on telephone poles. New posters are often stapled directly on top of shabby old ones, which echoes the growth rings in the tree trunk they're stapled to.

Glen Otto Park expedition



[View Larger Map]

Today's adventure takes us out to Troutdale's Glenn Otto Park, on the Sandy River. The park is mostly famous for the sort of safety issues that result when you combine warm weather, cheap beer, testosterone, and a very cold, fast river. Which is something that's come up in a few earlier posts (the High Rocks one for example), and I'm not really interested in revisiting the topic. The problem is that I'm not sure what else there is to say about the place. I stopped by just to take photos of the bridge next door, and I ended up with some photos that weren't of the bridge, and here they are.

I did manage to find a few non-picnic, non-drowning-related items to pass along, so here they are as well:
