59351. Aerial Lift Bridge: Aerial View of Duluth Canal and Harbor

Date Created:
1944-1952
Description:
On Monday, July 1, 1929, the suspended car made its last trip across the canal. The bridge's modification to operate with a lift span began on April 8, 1929, with a low bid of $448,000 by the Kansas City Bridge Company. The Aerial Lift Bridge was first operated on March 19, 1930. The bridge has a clearance of 138 feet when the lift section is completely up and when down it is 16.5 feet above the water. The length of the span is 386 feet and weighs 900 tons. The distance from the water to the lower edge of the truss is 172 feet 7 inches; to the top of the truss it is 227 feet. During the shipping season it makes about 25 lifts a day. The new bridge is owned and operated by the City of Duluth on permit authorized by Congress. The Ship Canal and grounds are under the authority of the Lake Superior Area Office of the U.S. Army Corps of Engineers.

59353. Aerial Lift Bridge: Aerial Lift Bridge and Ship Canal, Entrance to Duluth-Superior Harbor, Duluth, Minnesota

Date Created:
1950?
Description:
139-D The caption of this post card says The unique Aerial Lift Bridge and Ship Canal Entrance to Duluth-Superior Harbor is an outstanding attraction of this popular summer vacation city. Total bridge load lifted is 900 tons. Only 55 seconds are required to lift the span 135 feet. The Harbor is second only to that of New York City in shipping tonnage and through it passes about 60 per cent of America's iron ore production, from the great iron ore ranges just north of Duluth. Another fact, not included in the caption is that John H. Darling (1847-1942), U.S. Engineer for Duluth-Superior Harbor, oversaw replacement of the original wooden canal piers with concrete piers in 1897. The piers have been maintained and repaired with a major remodeling/rehabilitation in 1985-1986.

59360. Aerial Bridge: Whaleback Leaving Duluth-Superior Harbor Loaded With Ore, Duluth, Minnesota

Date Created:
1910?
Description:
Whaleback is an unusual ship design with steel hulls (body of the vessel) and rounded decks (boat, hurricane, main -which is the lowest full-length deck in a ship's hull, and spar are all decks at different levels) which was introduced by the inventor Captain Alexander McDougall of Duluth in 1888. It was a very stable vessel. American Steel Barge Company, a New York corporation engaged in shipbuilding and transportation on the Great Lakes as well as on the Atlantic and Pacific coasts, purchased all of the patents for McDougalls whaleback vessels for $25,000. The only remaining whaleback is the Meteor, which is now a museum at Barker's Island in Superior, Wisconsin.

59361. Aerial Bridge: View of Minnesota Point, Duluth, Minnesota

Date Created:
1920?
Description:
This photograph may have been shot from Seventh Street and about Lake Avenue. The bright narrow strip in the lower middle of the image is Lake Avenue leading to the Aerial Bridge. The rectangle and three dots parallel to the piers of the canal are the remnants of the Whitney rock crushing enterprise. The Whitney Brothers, of Superior, Wisconsin, had a sand and gravel processing business that was functioning in 1919. The concrete form that is still in the water was the dredging/crushing building. A tunnel ran from the building to the Point. There was a conveyor belt and railroad spur adjacent to the concrete building. Sand from the Apostle Islands and gravel from Grand Marais were carried to Duluth on a small vessel named Limit. The business also used a tug the William A. Whitney. The Limit was secured to the concrete building and the load of sand or gravel was unloaded into the steel hopper using a jaw-like clam shell, steam powered device. The belt conveyed the materials to shore and it dropped into a tunnel where trucks were ready. On Federal lake charts it is referred to as cribs. Telephone lines are in this photograph. In 1880, the first telephones were installed in Duluth by Walter Van Brunt for C. H. Graves and Company. In 1881, the Duluth Telephone Company was incorporated with $10,000 capital. In 1882, the first telephone directory was issued for 30 subscribers. In 1898, long distance lines between Duluth, Cloquet and Carlton were strung. In 1899, Duluth had 794 telephones. In 1900, the Zenith telephone Company (independent) started operations in competition with Duluth Telephone Company. The tower is the Central High School clock tower. The 1892 school has been the Central Administration Building for ISD 709 since the late 1970s.

59369. Aerial Bridge: Marshall-Wells Hardware Company Duluth

Date Created:
1906?
Description:
The information on this post card says Crowd leaving bridge; The Aerial Bridge; Miniature Train, White City. Joyland White City was the name of the amusement park at the end of Minnesota Point at Oatka Park. It was named White City based upon the buildings constructed at the recently experienced World's Fair where buildings were constructed using "white" building materials. There were rides and a pavilion for performances, dances and music. White City was short lived, about 1905-1911. The pavilion remained and the location reverted to the prior name of Oatka Park. The small train was moved to the Duluth zoo when the last features of the amusement park were dismantled in the 1950s. This post card was mailed in July 1907.
