Not mass transit related, but I saw in a few flickr photo streams, the state of Michigan is demolishing the Pier 19 approach spans that appeared in 2009 at the Ambassador bridge. At one time, these approach ramps would connect to a cable stayed structure. That will not happen. For once something NOT being built in Detroit is great news.
