A Bryant elementary third grade classroom of boys and girls with their teacher. The children are seated at their desks, the unidentified woman teacher is standing at the rear of the room. Blinds are drawn, but sunlight is peeking in below the one near the teacher. The classroom is full of interesting items, but the drawing of the Aerial Bridge on the large blackboard is delightful. The day's schedule is on the back corner blackboard. Drawing is a twenty-minute slot after lunch and before geography. Jane, Rose, Edith, Grace and Irene are named Busy Workers and have stars by their names on the blackboard.

The Claude Turner design for the original Aerial Bridge from 1901. Many companies and designers vied for this project. The bridge was built in 1904-1905. This drawing shows the spires and steel structural detail as well as the concrete footings and dimensions. Both towers are shown with an end view. In 1929 the suspended car transfer was eliminated and a lift span was installed.

The post card caption says The Aerial Bridge, Span 393 feet 9 inches, 135 feet high from water line. Cost $100,000. This post card illustration is of a view from the waterfront. At the right is the South Breakwater Inner Light Tower. Houses on Minnesota Point are at the far right. Engineer C.A.P. Turner, of the Gillette-Herzog Manufacturing Company of Minneapolis, designed the Ferry Bridge with Suspended Car Transfer in February 1901, meeting federal specifications. Bids were opened March 25, 1901, but only one was received. The Duluth Canal Bridge Company was awarded the contract but abandoned the work. In February, 1904, the Modern Steel Structural Company of Waukesha, Wisconsin was issued a contract. Work began July 20, 1904.

The caption of this post card says Clear span, 400 feet; clear height, 136 feet; total height above water, 186 feet. This view shows the waterfront when it was warehouses and wharves, docks, railroad freight sheds and slips. This view is probably from Skyline boulevard which, at this time, would have been called Rogers' Boulevard. William Rogers was the first parks department commissioner. In December 1959 the Duluth City Council and Mayor E. Clifford Bork changed the name of Rogers parkway and Skyline Boulevard to Skyline Parkway.

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.

There are three drawn details: end view, part side elevation, lateral bracing in horizontal plane. The towers are the two end parts of the bridge that hold the central span and the suspended car. The towers are referred to as North and South. The South Tower is nearer to Minnesota Point, the North Tower is on the "mainland." Drawing 167, Sheet M11.
