Improvements to the I-80/SR 65 Interchange

We have reached a major milestone to reconfigure the Highway 65 interchange at Interstate 80! The final environmental document for the entire interchange was approved in September 2016 and Caltrans has signed off on the proposed improvements.

The original interchange was constructed in the mid-1980’s, when the population of Placer County was 136,000. Over the last 30 years, the population has grown to 370,000 with traffic reaching 115,000 vehicles per day on Highway 65. In 2008, Caltrans began a preliminary study to reconfigure the interchange and developed several concepts that were used to begin the environmental phase in 2010. Over the past six years, PCTPA has successfully been working with federal, state, and local partners to balance the needs of local access and regional travel on the interstate.

How will the Interchange be reconfigured?

We began with 22 concepts and through a process that involved significant public outreach, we now have environmental approval to add one additional lane to each of the four connectors between Highway 65 and I-80. The improvements also include maintaining the existing I-80 access at Taylor Road and eliminating the existing vehicle weaving on I-80 eastbound between Eureka Road and Highway 65.The video shows the planned interchange improvements.

When will construction on the interchange begin?

The interchange will be constructed in phases, with the first phased planned to begin construction in 2017!
Caltrans is already moving forward with design of the first phase of the interchange that will provide a third lane on northbound Highway 65 from I-80 to Galleria Boulevard/Stanford Ranch Road and improvements to the local interchange.

Future phases of the interchange are depended on availability of funding for construction. There are also plans to widen Highway 65 from I-80 to the City of Lincoln, more information can be found here.
