The City of Sacramento made a big announcement Wednesday about the replacement of the I Street Bridge. San Francisco-based architecture firm, T. Y. Lin International has been selected to design and build the new bridge. Sacramento Mayor Derrel Steinberg said this project has been a long time coming and that this will be the first bridge in over 50 years to cross the Sacramento River. The replacement for the I Street bridge will be built between the Sacramento Railways and a planned development in West Sacramento near C Street. The project is estimated to cost $172 million, 88 percent of the funding will come from the federal government.
