L. SUPERIOR
MACKINAC STRAITS BRIDGE
This engineering masterpiece, one of
man's truly great achievements, forms
a 4-lane ribbon of highway over the
turbulent straits of Mackinac between
St. Ignace and Mackinaw City, Michi-
gan. Its contribution to the economy
of Upper Michigan and the North
Country cannot help but be signifi-
cant. The overall length makes it
the longest bridge of its type in the world. Opened in
November of 1957, it carries thousands and thousands of
vehicles between the two great peninsulas of Michigan.
