Stanislaus River Bridge Project, California

The Altamont Corridor Express (ACE) is one of California’s most popular commuter rail services. It links the Central Valley with Silicon Valley. As part of the expansion of the ACE to Stanislaus, Merced and Sacramento counties, SENER was selected to design the Stanislaus River Bridge, a new single-track concrete bridge crossing over the Stanislaus River on the Fresno Subdivision.

The new bridge will be a 760-feet long 20-span structure with two abutments at each end of the bridge and 19 piers between the span sections and two supporting piers in the river. 

The project includes the following disciplines: 

• Structural engineering and bridge design

• Geotechnical investigations and hazardous materials assessment

• Permitting and Environmental support

• Coordination with Union Pacific Railroad

• Hydrology and hydraulics analysis

• Utilities coordination

• Land surveying and right of way support
