The next three photos show the various stages in the progress of the East abutment. The base foundation is in place and the crews are placing rebar in preparation of forming and pouring the actual girder bench.
These next four pictures show the formed columns for the center pier, the columns after form removal, and the platform for formwork for the pier cap.
This photo shows the formwork at the top of the West caissons, which will remain buried. Ground level of these forms is the bottom of the pier cap.
