I was researching the area tonight and why the bridge looks like does is probably the result of a flood that happened in 1935. Three bridges had been destroyed. The one that made the newspapers was a footbridge in a part of the park near downtown. This part of town, however, was part of Roswell which had been annexed by Colorado Springs in the early 1900's.
The main power plant for the city happened to be located in the center of Roswell. Around this area was a large number of coal mines that were dug into the bluffs and hillsides. I live a short ways from this bridge however and the ground consists of fill from the mines. This I researched once I found out about the mines as I didn't want my house falling into an abandoned mine shaft.
Apparently around Rockrimmon Blvd that's been an issue. There was also drainage issues where Nevada Ave and I-25 meets. Of course that intersection has about eight mines extending outward according to the Bureau of Mines map. I will note that directly across Nevada Blvd from where I live are some abandoned mine shafts. I'll note that not too far away you can see two of the beehive shaped kilns that was used to take the coal and bake it into coke for power plant. The power plant has been modernized but it's still there.
