Project Description

The bridge may be built at one of two locations along the Sacramento RiverThe 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 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.

The Mark Thomas Company, Inc., in association with Modjeski and Masters team, was selected and awarded a contract at City Council on March 18, 2014. The project should complete the environmental documentation and preliminary engineering by mid-2016.
