Sacramento will begin accepting contractor bids on March 25 for the I Street Bridge replacement, a project that improves vehicle, bike, and pedestrian access.

SACRAMENTO, Calif. — The City of Sacramento is gearing up for the next phase of the I Street Bridge Replacement Project, with bids from contractors set to be accepted starting March 25.

According to city officials, the project is moving into the formal advertising phase. Contractors interested in submitting proposals can review bid information on PlanetBids, the city’s online procurement platform. 

Once bids are received, the city anticipates awarding a contract in late April or early May, assuming proposals are within the project budget. 

Construction on site could begin in late May or June after the selected contractor mobilizes.

The project involves building a new bridge upstream of the existing I Street Bridge to serve vehicles, bicycles, transit, and pedestrians. 

The current bridge, which is more than 110 years old, has narrow lanes and limited accessibility and will continue to carry rail traffic. 

After the new bridge opens, expected to take about four years of construction, the existing bridge’s upper deck may be converted for pedestrian and bicycle use as a separate project led by West Sacramento.

Officials note that public engagement has been extensive throughout the planning and design phases. Construction-phase outreach will begin once bids are received and contract awards are confirmed. 

The project is designed to improve mobility, support economic development, and provide better access to Sacramento’s Railyards and West Sacramento’s waterfront.

Estimated construction and delivery costs for the new bridge range from $260 million to $320 million. Funding comes from a combination of local city contributions, federal matching funds, and programs, including the Highway Bridge Replacement funding, the SB1 Local Partnership Program, and the federal Bridge Investment Program.
