So, instead of going downtown looking for some cool architecture, I decided instead to go to the bridge nearest my home, and photograph it. That bridge is actually a concrete overpass for the highway above, probably built in the 50's like so many of them were. Nothing special, certainly nothing fancy, and driving over it at 50 mph you'd never give it another thought. The view from beneath begs a different response.

The bridge acts as more of an 'underpass', but is a bridge structure nonetheless. Alongside a creek and a road, a bike path crosses beneath it; runners, cyclists, moms and kids and dogs alike, all crossing underneath the highway. As large trucks passes overhead, I'd occasionally hear things hitting the street, presumably small chunks of concrete, falling from above. I never saw anything, but the noise was coming from the same place, beneath what looked to be a patch on the bottom side of the roadway (there were several such patches).

If you want to see a few more, feel free to check out:

Keep on shooting!

wow, that is kinda scary...and is a great way of showing how our design codes have changed since the 50's. I like your perspective here, and the rough, broken textures.

Yikes, I think I would report that. Cool angle on the shot though.

Having previously seen--and reported--one of these bridges that I thought was in imminent peril, I would certainly report such a hazard (that bridge has since been replaced). I don't think this structure is compromised, but some of the band-aids they've added are not sticking.

You actually wouldn't believe the 'band-aid' in the case of the replaced bridge, which was about 1/8 mile from this one (I'll have to search for the photos). The concrete columns had vertical re-bar that was compressing downwards, actually bowing outwards, spalling concrete all over the place. About a year before finally replacing the bridge, CDOT came out and installed 1" stainless steel straps surrounding the compression, and then concreted over it to cover it all up. I'm no mechanical engineer, but man, was that scary looking!
