San Joaquin River Viaduct

Craft workers pour concrete for the pergola deck structure that will carry trains over the existing freight rail lines at the San Joaquin River Viaduct. On the south bank of the San Joaquin River crews are also busy finishing up construction of pier caps to tie together the few remaining support columns. The cast-in-place construction of the deck is also progressing, tying all the individual components of the structure together. The completed viaduct will form one of the largest structures on this first phase of the high-speed rail project.
