The existing I-80/SR 65 interchange was constructed in late 1985. Because of the region’s growth over the past two decades, the interchange and the I-80 and SR 65 corridors are experiencing increasing traffic congestion. The high traffic demands during the commute hours and the recreational trips to the Sierras congest the project area on a regular basis. The I-80/SR 65 interchange improvements project is intended to reduce traffic congestion, improve operations and enhance safety.
The overall project consists of the following phases:
- Project Study Report (completed by Caltrans in 2009)
- Project Approval and Environmental Document (currently underway)
- Final Design and Right-of-Way Acquisition
The Project Approval and Environmental Document (PA&ED) phase will analyze alternatives, recommend a solution and summarize environmental issues and clearances. Work began in March 2011. It is anticipated to be completed by 2015.
Typically, it takes an additional 4-5 years to complete the design and construction phases. However, because of funding uncertainties, it is expected that the project will be designed and constructed in phases, as money becomes available. The time to complete the overall project may take 20 years or more.
The PA&ED phase is funded by $3.9 million in construction savings from the I-80 Bottleneck project. Preliminary cost estimates for the overall project range from $230 to $280 million. Funding for the overall project has not yet been identified.
To further fund work on this project, $5 million in future developer impact fees has been identified, though the timing for availability of this funding is unknown. State and federal discretionary funds – should they come available – will also be pursued.
Caltrans is the project lead. The Placer County Transportation Planning Agency (PCTPA) is the local sponsor. PCTPA is actively encouraging input from the cities of Lincoln, Rocklin, Roseville and County of Placer along with vicinity property owners, businesses, and others. CH2M HILL is leading an engineering and environmental consultant team for the PA&ED work.
