The website Michigan History was produced by someone at MSU. While I have no idea who or why they gave up on what was shaping up to be a cool website, the history checks out. The page on Port Huron’s Blue Water Bridge says:
Perhaps Port Huron’s greatest claim to fame is the Blue Water Bridge, a historic arcing bridge that serves as a means of transportation between Canada and the United States. The bridge is located over the St. Clair River, and connects Port Huron, Michigan, to Sarnia, Ontario. In 2013 the Blue Water Bridge celebrated its 75th anniversary, and a closer look at its history show why Port Huron residents take pride in the structure.
The original Blue Water Bridge was constructed in 1938, and was built by the American Bridge Company of New York, and the Hamilton Bridge Company of Ontario. The original bridge is an arch cantilever bridge, which was designed to not only support large amounts of traffic, but also to have an aesthetic arching look. In the late 1980s the border crossing became so popular that plans for a new bridge were brought up. However, instead of demolishing the old bridge, a new one was built in 1997 beside the old bridge, to support eastbound traffic.
The Michigan cost for building the new bridge, and renovating the old one was $62.6 million dollars. (Michigan Department of Transportation) The project was considered an enormous success and won awards from the American Society of Civil Engineers, the Ontario Institution of Steel Construction, and the Federal Highway Administration. For Port Huron residents the bridge signifies the close connection with Canada, and the willingness of the two sides to work closely together.

There’s more Michigan bridges on Michigan in Pictures, and since you’ve read this far, Boatnerd’s page on the Saginaw has everything you’ll want to know about the self-unloading bulk carrier that was launched May 9th, 1953 as the John J. Boland. It’s one of three near sister vessels built by this shipyard: The John G. Munson which is still plying the lakes and the Detroit Edison that suffered a career-ending grounding in Lake Michigan in December of 1980.
