McCord Creek Bridges

One of the many ongoing projects involves tracking down historic bridges in the Columbia River Gorge. I kind of like this project because it involves making repeated trips out to the Gorge, but then stopping places and taking photos of things that nearly everyone else ignores. Many of the posts in the project come from in the surviving stretch of the old highway between the Vista House and Elowah Falls, more or less; for long stretches further east the route of the old road is directly beneath today's freeway, and nothing survives of the original. This is basically what happened at McCord Creek, the creek that flows over Elowah Falls. A century ago a tall and sort of spindly bridge was built to carry traffic over McCord Creek. Like many of the bridges along this stretch of the highway, it was designed by Karl P Billner. The bridge at McCord Creek was more utilitarian than most of the others, and it was maybe not Billner's most distinctive work, but it still bore a passing resemblance to his Latourell Creek bridge. The bridge was apparently tougher than it looked; it seems it was incorporated into first the US 30 highway and then Interstate 84 when they were constructed, and for nearly 80 years it carried traffic much faster and heavier than its designers could have ever imagined. As far as I know none of the other bridges from the old highway were reused as part of the new freeway, so I suppose it had that going for it. It was finally showing its age by the late 1990s, and the state concluded there was no way to bring it up to modern seismic standards, so it was demolished and replaced by a modern bridge in 1997-98.

The photoset above has a few shots of the replacement bridge, and ODOT has a better photo from an angle I wouldn't attempt, of workers doing a job I also wouldn't attempt. That bridge isn't the main point of interest in this post, though. In 2013 ODOT opened another segment of their Historic Columbia River Highway Trail. For those who aren't familiar with this project, it's not a trail in the same sense as, say, the loop trail around Multnomah & Wahkeena falls. It's more of a fancy bike path along I-84; it's several steps up from riding along the freeway shoulder, which people had been doing (completely legally) for decades before they started building the new trail. But if you're looking for a prime wilderness experience, this is probably not the trail for you. They're trying to reuse abandoned bits of the original highway where they can, but when that isn't possible the trail usually runs right next to the freeway. When they got to building the McCord Creek segment, it seems the 1998 bridge wasn't designed with room for a bike path, so the trail would need a new bridge of its own. Instead of building next to the freeway, the trail jogs south and away from I-84 for a bit to a spot where they could build a smaller and probably much less expensive bridge. They put a bit of design work into the new bridge, and it's done in a style that evokes the old highway's historic bridges but isn't quite identical to them. It has a bit more of an Art Deco look to it, as if they'd somehow continued building Gorge bridges into the 1920s and 1930s.

Beyond the two bridges shown here, there are a couple of others I should at least mention. There's a railroad crossing of the creek just north/downstream of the I-84 bridge; I can't really make it out in my photos, but I think it might be more of a culvert than a proper bridge. And upstream of here, Gorge Trail #400 crosses the creek near the base of Elowah Falls. An old OregonHikers thread has a very old photo of yet another bridge that crossed halfway up the falls, in the manner of the Benson Bridge at Multnomah Falls. It's too bad that's gone now, but I can see how a wooden bridge wouldn't last long in that spot.
