View of the rising sea smoke at sunrise. Sea smoke is a cloud over the sea, which could otherwise be called fog, and is usually formed when very cold air moves over warmer water. We see this phenomena all the time when watching Lake Superior. Photographers capture it with delight. The Blatnik or High Bridge is in the distance behind the Aerial Bridge. It is also known as the Duluth-Superior High Bridge or Blatnik High Bridge or Interstate Bridge. Efforts to secure a toll-free bridge between Duluth and Superior started as early as the 1930s. Other unsuccessful attempts were made in 1940 and 1948. In 1953, approval was given for a new toll bridge, pressure from both cities demanded a toll-free unit. When Congress adopted a new system of interstate and defense highways, the bridge became part of that system and was eligible for 90% federal financing - elevating the need for having it be a toll bridge. In 1956 construction plans were delayed by disagreement over clearance height. It had been set at 100 ft. but, after much debate, increased to 120. Construction started Nov. 28, 1958, on what was the largest single highway project ever undertaken jointly by Minnesota and Wisconsin. About 1.6 million hours were worked by construction employees and 100,000 by engineering and inspection personnel. Three workmen lost their lives in the three years of construction. The bridge was formally dedicated on Saturday, Dec. 2, 1961. Mayor Lawrence Hagen of Superior, E. Clifford Mork, Duluth Mayor. It was formally named to honor John A. Blatnik Sept. 24, 1971.
