A Tale of Two Bridges.  Independent Researchers Compare and Contrast the Bay Bridge with the New Tappan Zee Bridge.

A team of researchers from Duke University, working in conjunction with the Alliance for American Manufacturing (AAM), have issued a new report titled Infrastructure Investment Creates American Jobs. Their report argues the U.S., with the largest infrastructure as measured by combined bridges, airports, seaports, and miles of road, rail, pipeline and inland waterways, is old and broken and the piecemeal federal approach to investment has cost the country 900,000 jobs, including 97,000 jobs in manufacturing.

Chapter 3 – A Tale of Two Bridges – compares the San Francisco-Oakland Bay Bridge project with that of New York’s new Tappan Zee Bridge and makes a strong case for the Buy America provision required for federal funding. As some have come to know, California did not request federal funds and therefore was not subject to Buy America. The economic results of that decision are dramatic: the project was $3.9 billion over budget, 12 years late, and hired 3,000 Chinese workers. These numbers are compared in great detail against the yet to be completed Tappan Zee Bridge, which did receive federal funds and therefore is subject to Buy America.

World Steel Bridge Symposium/NASCC Presentation Videos Available.

All presentations from the 2014 WSBS/NASCC conference in Toronto are available for download or online streaming through the AISC website at www.aisc.org/2014nascconline.

Joseph Bertolozzi uses the Mid-Hudson Bridge to make Music.

Bridge Music

Joseph Bertolozzi’s latest public art project Bridge Music, is a unique sound-art installation featuring New York’s Mid-Hudson Bridge as the instrument itself.

Launched during the 400th anniversary celebrations in 2009 of Henry Hudson’s voyage up the Hudson River, Bridge Music was created by recording the sounds of the bridge’s surfaces (guard rails, girders, etc.) with various mallets and using those sounds to compose new works, making the Mid-Hudson Bridge the largest percussion instrument in the world. These performances of the bridge’s sounds are what one hears at the bridge’s Listening Stations and on the park radios. The music contains no other tones than those of the bridge itself.
