JJA Bridge in ENR.com article

By Robert Thompson, on January 21st, 2008

An article entitled “Historic Cable-Stayed Link Taking Shape in Louisiana” about the construction of the John James Audubon (JJA) Bridge in Louisiana is on ENR.com here. The drilled shafts actually extend much deeper than indicated in the article, for what its worth. I think they were only talking about the permanent casing, not the entire drilled shaft.
