How many bridges are there across the Mississippi? Depends on the source you look at - 130? 133? 142? It also depends on how you define a functioning bridge. St. Louis City and County have nine, if I count correctly, two of which are exclusively for railroad use. But there is another one that used to carry historic U.S. Route 66 across the river that is so narrow and worn that it can now only be used for pedestrian sightseeing.
This one is the Alton Bridge, north of St. Louis, from St. Charles County, Missouri, to Alton, Illinois. The eagle in Monday's post was just up and to my left from the place I took this picture.
