Construction Method and Specifications
The approach superstructure was built on a combination of nine temporary bents and three permanent bents (each side). After the pylons were completed, the main span is constructed one segment at a time, with the cables installed and main span tied back to the already completed approach span behind. Deck construction follows shortly behind the steel, and a crawler crane services both tasks from the deck.
