Photo taken when the 62nd Street Bridge in Pittsburgh was cited on August 20, 1963 by the American Institute of Steel construction as ‘the most beautiful steel bridge in its class when it opened to traffic in 1961. The 62nd Street Bridge, known officially as the Senator Robert D. Fleming Bridge, is a four-lane divided, steel subdivided Warren deck truss bridge that spans the Allegheny River. The length of the main channel is 370 feet with the deck at a height of 50 feet. This bridge replaced the old Sharpsburg Bridge and is the last numbered street in a grid, which began at the Point in downtown Pittsburgh and extends along the Allegheny River through the Strip District and Lawrenceville (Arsenal).

Johnny G Arch Sr.: The mill in the foreground - Lawrenceville - They made turrets for Army tanks . It was Union Steel Casting Co. [Other comments indicate this was a division of Blaw-Knox.]
David Smith: NOBODY calls this the Fleming Bridge. It's the 62nd Street Bridge and always will be. Harrisburg's obsession with naming bridges after political hacks has never caught on.
Jim Missenda: Original bridge was wooden deck and sidewalk. Used to ride the Rt. 94 streetcar to visit my grandmother in Sharpsburg.

The 62nd Street Bridge in Pittsburgh, officially known as the Senator Robert D. Fleming Bridge, was celebrated for its striking design and was recognized by the American Institute of Steel Construction as "the most beautiful steel bridge in its class" when it opened in 1961. Spanning the Allegheny River, the bridge is a four-lane divided, steel subdivided Warren deck truss bridge, with a main channel length of 370 feet and a deck height of 50 feet above the river.

This bridge replaced the old Sharpsburg Bridge and was part of the larger transportation grid extending from the Point in downtown Pittsburgh, running through areas like the Strip District and Lawrenceville (Arsenal). Its design not only served a functional purpose but also added a modern architectural element to Pittsburgh's skyline, contributing to the city's mid-century urban development.

The 62nd Street Bridge continues to serve as a vital connection in the Pittsburgh area, and the recognition it received highlights its importance in both engineering and aesthetics.

The 1963 photo at the top shows how much of the hills they had to remove to make room for PA-28. This street view is another example of how trees grow like weeds in the eastern US.
