Society Of American Military Engineers
The Society of American Military Engineers (SAME) unites public and private sector individuals and organizations from across the architecture, engineering, construction, environmental, facility management, contracting and acquisition fields and related disciplines in support of the United States' national security. SAME connects architects, engineers and builders in the public sector and private industry, uniting them to improve individual and collective capabilities to provide the capability and prepare for and overcome natural and man-made disasters, acts of terrorism and to improve security at home and abroad. That goal grew from America's experiences in World War I in which more than 11,000 civilian engineers were called to duty upon the United States entering the conflict. Returning home after "the war to end war," many feared the sector would lose this collective knowledge and the cooperation between public and private sectors that proved vital to combat success.

Fort Duquesne Bridge
The Fort Duquesne Bridge is a steel bowstring arch bridge that spans the Allegheny River in Pittsburgh, Pennsylvania. It was colloquially referred to as "The Bridge to Nowhere". History The bridge was constructed from 1958-1963 by PennDOT, and opened for traffic October 17, 1969 with its predecessor Manchester Bridge (located closer to the tip of Point State Park) closing that same day (it was demolished in the autumn of 1970). The bridge was given the name "The Bridge to Nowhere" because the main span was finished in 1963, but due to delays in acquiring right of ways for the northern approach ramps, it did not connect on the north side of the Allegheny River. The total cost was budgeted at $5 million in 1962. The lack of approach ramps meant the bridge ended in midair, rendering it useless. On December 12, 1964, Frederick Williams, a 21-year-old chemistry major at the University of Pittsburgh from Basking Ridge, New Jersey, drove his 1959 Chrysler station wagon through the ...

Jerome Street Bridge
The Jerome Street Bridge is an arch bridge across the Youghiogheny River connecting the east and west banks of the Pittsburgh industrial suburb of McKeesport, Pennsylvania. The bridge is a rare steel crescent arch bridge. A crescent arch is formed when the intrados and extrados (the ribs) of the arch are not parallel, but instead form two different curves beginning and ending together. The ribs form a truss at the top of the arch and join together in a solid rib at each end. A crescent arch is a two-hinged arch, the ribs are further apart where the bending moment is greatest and close together at each hinge where it is minimized. History and architectural features This bridge was engineered by George S. Richardson. A Great Depression-era public works bond was provided to fund the creation of a new auto-centric four-lane highway bridge. The bridge was dedicated on May 3, 1938 and opened to traffic on May 4. Thousands of people attended the ceremony and parade to celebrate the new ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
