Interstate 5 / Richards Boulevard Interchange Project

I-5 Richards Boulevard


The City of Sacramento is undertaking a preliminary engineering and environmental study to improve the Richards Boulevard / Interstate 5 Interchange. Operation of the I-5 / Richards Boulevard interchange is currently deficient as indicated by traffic congestion on I-5 and Richards Boulevard during peak commute hours. This congestion will only continue to grow as redevelopment occurs in the area unless improvements are made to the transportation system. 

The interchange was last studied by the City in 2010 which resulted in the widening of Richards Boulevard, improvements to the interchange off-ramps, and reconstruction of portions of Jibboom Street. These improvements provided interim traffic relief, but were never intended to accommodate all the development planned for the River District and Railyards. The City is now preparing an environmental document to further study the interchange and identify a preferred long-term solution for current and future congestion.


The purpose of the project is to provide long-term operational and circulation improvements to address existing congestion and accommodate future traffic volumes resulting from area development. The interchange will be designed to accommodate a 20-year traffic forecast from the year it is completed. With the project's current schedule, the interchange is anticipated to accommodate traffic through 2047. Below is a graphic depicting travel times in and around the interchange in 2019 and travel times in the year 2047 if no improvements are made.

 Costs and Funding

The cost of the interchange has yet to be determined, pending the outcome of the environmental process and the preferred project alternative. Construction costs  for the alternatives considered in the previous study ranged from $24 million to $63 million (2010 dollars, unadjusted). The project is currently funded through the design of the interchange with Regional Surface Transportation and Measure A funding, which will require compliance with both the National Environmental Policy Act (NEPA) and the California Environmental Quality Act (CEQA).
