I sure hope this picture is right side up when I post this!
Then if you drive down a little bitty alley along the river bank, you'll see folks live in these cool old houses and this ones side-yard is what used to be under the bridge. It's kind of like looking at the back side of the tourist areas.
This plaque tells the milestones of the bridge that isn't there anymore. It was dedicated in 1936 and demolished in 2001 after flooding damaged it and it was replaced by a new bridge further upstream.
