SanJoaquin River Viaduct

On the south side of the San Joaquin River, crews are finishing up construction of pier caps to tie together the support columns. Once that process is complete, girders will be set to begin construction of a deck that high-speed trains will use to connect to the pergola section further south. The viaduct will carry high-speed trains over the river and freight line to form one of the largest structures on this first phase of the project.
