A newspaper, the Lansing Republican, dated February 5, 1884, reprinted a story from the Grand Traverse Herald pointing out that the experiment to provide all-year service across the Straits by boat had failed, and that if a great east-west route were ever to be established through Michigan a bridge or tunnel would be required.

The Mackinac Bridge website give facts, figures and historical information about the steel suspension bridge that connected lower Michigan with its upper peninsula after other transportation solutions failed. The Mackinac Bridge is a great example of how modern engineering gradually transformed all parts of the United States. The site includes a brief historical essay with background about the bridge, a list of bridge stats, images, an archive of traffic reports (only going back to the early 1990s, and links to other sources of information. The site is run by the Mackinac Bridge Authority and the site is well designed and well maintained.
