I get you now Vic, I just didn't understand the way you phrased the question.
That rail line runs through the north side of Chicago on an elevated embankment and a city street crosses under it about every quarter mile, one busy street alternating with one side street. This is one of the side streets. They were built in the 1890s and in need of replacement.
The old bridge was built on abutments made of large limestone blocks set on a 5' thick concrete footing. The new bridge is sitting on concrete abutments which were made with brick texture form liners to give them the look of stone block similar to the old bridge. Instead of just sitting on a footing, these abutments are on 75' deep caissons that go all the way down to bedrock. If the old bridge lasted over 100 years, the new one should double that.
