Rocklin Road Interchange Improvements Project
The City of Rocklin is making long-term operational and circulation improvements within the area of the Rocklin Road/Interstate-80 Interchange. The improvements will address existing traffic congestion and improve walking and biking connections between downtown Rocklin and Sierra Community College.
Take our community questionnaire to help inform the planning and outreach process.
Rocklin Road is a prominent east-west arterial roadway including a five-lane undercrossing with a narrow sidewalk, no shoulders, and no bike lanes.
The City is proposing to reconfigure the interchange into a Diverging Diamond Interchange (DDI) and a separate crossing of Interstate 80 to allow for better bicycle and pedestrian connections between Sierra Community College and Rocklin’s Downtown.
Rocklin Road is a prominent east-west arterial roadway that connects between Sierra Community College and downtown Rocklin. The Rocklin Road Interchange Improvements Project will make many enhancements that benefit the community including:
- Improved walking and biking connections between Sierra Community College and Rocklin’s downtown core
- Increase in the movement of people and goods through the area to support the growing Placer region
- Relief of car congestion on Rocklin Road
- Safety improvements for motorists, bicyclists and pedestrians
- Promotion of multi-modal transportation through the area (taking transit, walking, biking)
The Rocklin Road Interchange Improvements Project is funded by Local City of Rocklin Developer Impact Fees and Regional South Placer Transportation Planning Authority (SPRTA) Developer Impact Fees. The total project cost is estimated to be $40 million. While environmental and design are funded, the City of Rocklin will seek state and federal funding for construction.
The Rocklin Road Interchange Improvement Project is projected to begin construction in 2026, with the tentative timeline for the following phases: the environmental phase (2021-2022), design phase (2023-2025), and the construction phase (2026).
