San Joaquin River Viaduct & Pergola

In north Fresno at the San Joaquin River Viaduct, crews have begun placing concrete to form the center spans of the viaduct’s signature arches – representing the entrance into the City of Fresno. Crews have also begun stripping the falsework of the arches on either side of the viaduct.

Crews are installing metal decking over the river, forming the floor of the San Joaquin River Viaduct. Once concrete has been poured to form the deck, work will begin on the signature arches that will serve as the “gateway” to Fresno County. The completed viaduct, nearly a mile in length, will be one of the largest structures on this first phase of the high-speed rail project.

At the San Joaquin River Viaduct, foundations have been poured for a cast-in-place concrete arch that will act as the high-speed rail gateway to Fresno County. Other sections of the viaduct continue to be constructed on the north and south banks of the San Joaquin River. Crews are installing metal decking over the river, concrete super structure elements are being poured to the south of the river, and deck drainage is being installed on completed sections.

At the San Joaquin River Viaduct, foundations have been poured for a cast-in-place concrete arch that will act as the high-speed rail “gateway to Fresno County.” Nearby, a worker uses a high-pressure hose to blow debris out of the rebar in preparation for another concrete structure pour. The completed viaduct, nearly a mile in length, will be one of the largest structures on this first phase of the high-speed rail project.

At the northern end of the San Joaquin River Viaduct, girders have been set and a cast-in-place concrete arch is underway for the section that crosses over the river. Concrete is being poured for the deck segments on the north side of the river, while further south, crews continue constructing barrier and intrusion protection walls along the sides of the pergola section of the viaduct. The completed viaduct, nearly a mile in length, will be one of the largest structures on this first phase of the high-speed rail project.

At the northern end of the San Joaquin River Viaduct, workers are busy with concrete pours as the cast-in-place structure gets closer to the river. Further south, crews have begun constructing barrier walls along the sides of the pergola section of the viaduct. On the south bank of the San Joaquin River, crews are finishing up construction of the remaining support columns, while on the north bank of the river the final pier cap has been poured. The completed viaduct will form one of the largest structures on this first phase of the high-speed rail project.

At the San Joaquin River Viaduct, workers have completed concrete pours for much of the pergola deck that will carry high-speed trains over the existing rail line (above). On the south bank of the San Joaquin River, crews are finishing up construction of the remaining support columns, while on the north bank of the river (below), the final pier cap has been poured. The cast-in-place construction of the deck is progressing and will follow with the completion of the pier caps, 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.

At the San Joaquin River Viaduct, workers continue pouring concrete for the pergola deck that will carry high-speed trains over the existing rail line. On the south bank of the San Joaquin River, crews are finishing up construction of pier caps to tie together the few remaining support columns, while on the north bank of the river, the final pier cap has been poured. The cast-in-place construction of the deck follows completion of the pier caps, 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.

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.

On the south side of the San Joaquin River, crews are finishing up construction of pier caps to tie together the support columns. The cast-in-place construction of the deck that will carry high-speed trains is also progressing, as it links all the structures together. On the north side of the river, other crews are working on the structures where the viaduct will tie-in to embankment. The completed viaduct will form one of the largest structures on this first phase of the high-speed rail project.

On the south side of the San Joaquin River, crews are finishing up construction of pier caps to tie together the support columns. The construction of the deck that will carry high-speed trains has also begun to link all the structures together. Concrete has also been poured for the pergola section at the southern end of the work area where high-speed trains will cross over the existing freight line. The completed viaduct will form one of the largest structures on this first phase of the high-speed rail project.

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.

Workers continue constructing the deck of the pergola section of the San Joaquin River Viaduct, tying rebar in preparation for a concrete deck pour. On the south side of the San Joaquin River, other crews build pier caps to tie together the viaduct support columns. The viaduct will carry high speed trains over the river and existing freight tracks to form one of the largest structures on this first phase of high-speed rail construction.
