Sacramento has locked in the final piece of funding for its long-awaited I Street Bridge replacement project, clearing the way for construction to begin in spring 2026 on what officials are calling a transformational infrastructure investment. The $300 million project received its final funding boost this summer when the California Transportation Commission approved an additional $25 million in competitive state funding.
The 114-year-old bridge connecting Sacramento and West Sacramento has become a daily source of frustration for commuters navigating its narrow lanes and outdated design. "It's super narrow, man," West Sacramento resident Jay Livello told KCRA. "Just having this part of the street busy, it's just bad."
From Historic Bottleneck to Modern Crossing
Built in 1911, the current I Street Bridge was determined in a 2011 Sacramento River Crossings Alternatives Study to have an upper roadway too narrow to serve buses, with no bicycle facilities and very narrow sidewalks. According to the Sacramento City Express, construction of the replacement bridge is estimated to cost $300 million total.
The funding package includes $250 million in federal Highway Bridge Program funds from Caltrans, with the remaining costs split between Sacramento and West Sacramento. Each city is expected to contribute between $13 and $32 million depending on the final financing structure, with City Council approval expected in September.
Design Competition Yields Modern Solution
The project's design emerged from an extensive public process that began after the two cities received a $76 million grant in 2016. As detailed by Wikipedia, officials opened a Bridge Architect Design Competition in 2018 that produced nine preliminary designs, eventually narrowed to four through community meetings and public input.
The final design released in February 2020 features a vertical-lift bridge spanning 860 feet with a 330-foot lift span. The new structure will include public seating, bike lanes, and larger sidewalks connecting Sacramento's Railyards District to West Sacramento's planned Washington Neighborhood, while the existing bridge's lower deck will continue serving railroad traffic.
Political Momentum Builds Support
The project has attracted significant political backing across multiple levels of government. U.S. Congresswoman Doris Matsui championed the initiative from its inception, even proposing the architectural design competition that shaped the bridge's final appearance. State Senators Angelique Ashby and Christopher Cabaldon have also played key advocacy roles in securing funding and fostering interagency collaboration.
Per Sacramento City Express, construction is expected to begin in spring 2026 and take approximately four years to complete. Key next steps include presenting the financing strategy to the Sacramento Transportation Authority in August and submitting a final finance plan to Caltrans.
Regional Infrastructure Push
The I Street Bridge replacement represents one piece of a broader regional effort to improve Sacramento River crossings. Sacramento and West Sacramento are simultaneously advancing the Broadway Bridge Project, which expects to start right-of-way acquisitions in 2025 with construction beginning soon after and lasting 36 months.
Assistant City Manager Ryan Moore said, "This is not just a bridge—it’s a once-in-a-generation investment in connectivity, safety, and opportunity for both cities," as mentioned by the Sacramento City Express. The project will be funded with $275 million from the state and additional federal support. It addresses long-standing Sacramento River crossing issues and will begin construction in 18 months, improving transportation between California’s capital and its growing western neighbor.
