Construction of the cast in place concrete connection between one end of V-shaped bridge pier and one end of concrete tension beam, which ties two ends of bridge pier together to carry their outward thrust. The key element is the tightly grouped reinforcing steel in the center of the photo. Wood forms will be built around the reinforcing steel, and ready-mix concrete will be placed to fill the forms around the steel. After this concrete has gained its strength, post-tensioning cables run through the white tubes will be tensioned strongly to connect the tie beam to the bridge pier. In the interim, highly stressed tension cables, circled in blue, provide support against outward thrust of the piers until the tension beams are completed.
