Structural Lifting and Support

George Washington Bridge Steel Repair and Rehabilitation, New York, N.Y.


Client: El Sol Contracting and Construction


Project Description: The George Washington Bridge is one of the busiest bridges in the United States. Maintaining the aging steel and concrete is a constant challenge as closing portions of the bridge are extremely difficult. As part of this project the contractor was required to perform steel and concrete repairs at several locations on the New York approaches to the George Washington Bridge. Several columns originally built in the 1920’s and 1930’s were severely deteriorated and needed repair.


Our Role: To repair the columns, a portion, or the entire column needed to be removed, therefore requiring temporary support.William J. Frank Engineering prepared the plans for the temporary support columns and associated bracing. Temporary columns were required to support both the upper and lower approach ramps. Temporary support loads were up to approximately 650 kips.
