SOLD OUT!  We have reached our capacity for tonight's Dinner Meeting.  Please join us in January!


Design and Construction Aspects of the Main Span, Cable Stayed Portion of the New NY Bridge

This presentation will discuss some of the design aspects for the main span portion of the New NY Bridge project that will replace the existing Tappan Zee Bridge over the Hudson River. This will include the Tower/Pylon configuration, the superstructure layout, the connection of the lower stay anchors to the edge girders, approach pier permanent tie-downs, the implementation of the redundancy truss and the 100-year service life design of the structure.  The presentation will then review the contractor’s level of success in implementing these design aspects into the construction of the project. 

Please register by Friday, December 2 to guarantee your place. Registrations made after that time will be accommodated if possible, but we cannot guarantee a place. 

See who's coming!


About the Presenter: Gowen E. Dishman, PE

During Mr. Dishman’s thirty-five-year engineering career, he has been involved in the design, construction, and the quality control/quality assurance of some of America’s most premiere and innovative bridge projects, starting with the one of the first modern segmental bridges built in the U.S. (Long Key Bridge in the Florida Keys) to Sunshine Skyway Bridge in Tampa Bay (pictured left) and the US 82 Mississippi River Bridge over the Lower Mississippi. His experience also includes light rail projects such as MARTA in Atlanta, Georgia and Tren Urbano in Puerto Rico and bascule bridge projects in Florida and Massachusetts.

Mr. Dishman has performed constructability and bid-ability reviews on many major bridge projects, including the US 82 Mississippi River Bridge in Greenville, Mississippi (pictured right); the Woodrow Wilson Bridge in Washington, D.C.; and the I-70, New River Bridge in St. Louis, Missouri. He serves on the American Segmental Bridge Institute’s Construction Practices Committee for Segmental Bridges.  This committee has just completed the 3rd edition of the “Handbook for the Construction of Segmental Bridges.”

Mr. Dishman is currently serving as the Main Span Component Lead for the New NY Bridge, which will replace the existing Tappan Zee Bridge.  He is a 1979 graduate of Tennessee Technological University and he has served as an HNTB Fellow since 2011.
