Existing I Street Bridge

Figure 1 - Existing I Street Bridge

Project Description

The cities of Sacramento and West Sacramento together have recognized the need for more river crossings. In 2011, the cities completed the Sacramento River Crossings Alternatives Study which identified the purpose and need for new bridge crossings. The study concluded that a North Market crossing was needed to replace the I Street Bridge.

The I Street Bridge is 100 years old and the lanes are too narrow to serve buses, there are no bicycle lanes, and sidewalks are too narrow to meet accessibility standards. The I Street Bridge Replacement project will include construction of a new bridge upstream of the existing I Street Bridge. The new bridge will cross the Sacramento River between the Sacramento Railyards and the West Sacramento Washington planned developments and provide a new bicycle, pedestrian, and automobile crossing. The existing I Street Bridge would continue to be used by the railroad. The approach viaducts to the existing I Street Bridge will be demolished, which should result in better access to the water front in both cities.

The project will improve mobility for motorists, bicyclists and pedestrians, and promote economic development by creating new access to the planned Railyards on the Sacramento side as well as better access to West Sacramento and the Sacramento River waterfront.

Costs and Funding

In February 2013, both City Councils directed staff to apply for federal funds for a new bridge across the Sacramento River north of the existing I Street Bridge. In May 2013, Caltrans authorized federal funds for the cities to begin preliminary engineering for all the associated improvements. The preliminary engineering phase is fully funded.

The cities of West Sacramento and Sacramento have agreed to share the local expenses associated with delivering the project. This includes federal matching requirements and other non-federally eligible expenses. Total project costs are currently estimated at $70-80 million.


As the lead agency, the City of Sacramento advertised a competitive solicitation for proposals from professional engineering teams to provide planning and design services for the new bridge. Based upon the merits of the proposals and conducting interviews, a panel of engineering staff from West Sacramento, Sacramento and Caltrans established the top ranked consultant team to accomplish the project approvals and environmental documentation necessary for the new bridge.

bridge architect Design Competition

In 2018, the cities developed and implemented a design competition to engage a bridge architect to join their team for the design of the new bridge.

The I Street Bridge Replacement project includes a community engagement program to inform and involve the community throughout the process. [Sign up to receive email updates]

Virtual Community Workshop - March / April 2019

From April 4 through 19, more than 1,300 community members provided their input through a virtual community workshop focused on community values, their future use of the new bridge, and the nine early bridge concepts.  Feedback received from the virtual workshop will help the cities and project team establish guiding principles for the bridge design and further refine the nine early bridge concepts which have been developed thus far.

Community Workshop - March 2019

On March 28, the cities of Sacramento and West Sacramento held the first community workshop to discuss bridge design options for the I Street Bridge Replacement Project. This workshop featured a short presentation by the lead architect and information stations with early possible concepts, ideas for bridge amenities, and other important considerations.

The city of West Sacramento is leading an effort to evaluate the feasibility of converting the upper deck of the existing bridge. Once the new bridge is built this project proposes to repurpose the upper deck for active transportation modes.



The project team completed a draft Environmental Impact Report/Environmental Assessment (Draft EIR/EA) for the I Street Bridge Replacement project. The Draft EIR/EA was released on September 28 and was available for public comment through November 12 at 4 p.m.

Community Meeting - October 2017

The cities of Sacramento and West Sacramento and the project team held a community meeting on Thursday, October 26, 2017 to provide a progress update about the I Street Bridge Replacement Project.  The project team had completed a draft Environmental Impact Report/Environmental Assessment (Draft EIR/EA) for the I Street Bridge Replacement project, which was available for public viewing at the time of this meeting.  Staffed information stations with maps and other project materials were available from 5:00 - 6:30 p.m. Community members were provided with an opportunity to provide input on the project and review the EIR/EA with the project team members.

Environmental Scoping Meeting - October 2014

The cities and the project team hosted an Environmental Scoping Meeting on October 9, 2014. The purpose was to provide a project update and to collect feedback from interested parties to help inform the environmental studies. The meeting provided project background, schedule, a summary of feedback from previous meetings and a review of environmental considerations. Immediately following the meeting, the project team took public members on a walking tour to show the proposed bridge crossing location and other site considerations.

Approximately 46 community members attended the scoping meeting and walking tour, and 10 community members submitted feedback regarding the bridge design, access, construction, and environmental concerns.

Community Open House - June 2014

The cities and the project team hosted a community open house meeting in June 2014. The purpose was to share information and receive input from the public about the project. The open house provided the project background and schedule and current phase of work as well as an opportunity for the community to provide feedback on specific bridge elements that should be considered when the project moves into the design phase, and to view other planning efforts within the project area.

Approximately 20 community members submitted feedback via comment cards about bridge design and aesthetics, access, and environmental issues. Overwhelmingly, community members expressed a desire to create a bridge that is bike and pedestrian friendly to encourage safe and direct travel between Sacramento and West Sacramento. In addition, community members encouraged the cities to expedite the project.
