Blue Water Bridge
The Blue Water Bridge spans the St. Clair River, and carries international traffic between Port Huron, Michigan, and Point Edward and Sarnia, Ontario. Located near the I-94 and I-69 interchange, the bridge forms a critical gateway linking Canada and the United States.
Fort Gratiot Lighthouse
Fort Gratiot was built in 1814 during the War of 1812 to guard the juncture of the St. Clair River and Lake Huron. Named after the engineer who supervised construction, Charles Gratiot, Fort Gratiot would be occupied on and off by the United States Army until 1879. With a surge of vessel traffic on Lake Huron in the early 1800s, the need for a Light Station to guide vessels through the water way became very important. In 1823 Congress approved the funds to build the first lighthouse in Michigan and the second oldest on the Great Lakes.
Fort Gratiot County Park
Fort Gratiot County Park is located in the northern part of St. Clair County, just off M-25 on Metcalf Rd. This 30 acre park offers breathtaking views of Lake Huron and 852 feet of shoreline and beach.
The HURON Lightship
Lightships are floating lighthouses that are anchored in areas where it was too deep, expensive, or impractical to construct a lighthouse. Lightships displayed a light at the top of a mast and, in areas of fog, also sounded a fog signal and radio beacon. The fog signals used over the years consisted of bells, whistles, trumpets, sirens, and horns. Early fog horns were powered by steam and later by air compressors. The HURON Lightship sounded her fog horn signal in 3 second blasts every 30 seconds and was known locally as “Old B.O.” because of the familiar sound her horn made.
