The I-Street Bridge is a historic through truss swing bridge carrying I Street over the Sacramento River in Sacramento, CA. It connects Sacramento with West Sacramento. Originally constructed in 1911, the bridge is 900 feet long with a 330-foot main swing span. The bridge carries highway access on the upper deck and railway access on the lower deck.
This project will include the construction of a new bridge upstream of the existing bridge. As a subconsultant to Mark Thomas, M&M was selected to design the movable span of the new I Street Bridge. Our portion of the design includes all structural, mechanical, and electrical design of the main span. Initial project tasks included a conceptual study and permitting. The project is currently in the preliminary and final design phase.
The new structure will accommodate highway traffic, bicycle lanes, pedestrian sidewalks, and accommodate a future street car. The project is expected to cost approximately $220 million. Final design for the project will be selected in 2020, with construction targeted to begin in 2021.
