State Route 49 Safety Assessment
In February 2020, a team including Caltrans and its transportation partners embarked on a safety assessment of the State Route 49 corridor between Auburn and Grass Valley to identify safety-related improvements that could be installed in the very near term, identify enhancements that could be added to planned construction projects, and plan longer-term projects to improve corridor safety.
For analysis purposes, the team divided the SR-49 corridor into four segments of similar characteristics based on features that include population density, traffic volumes and the rural or urban nature of the area. The existing safety features and collision history of each segment were assessed and used to outline recommendations for improvements to the corridor.
- Segment 1: Interstate 80 to Dry Creek Road
- Segment 2: Dry Creek Road to Wolf Road/Combie Road
- Segment 3: Wolf Road/Combie Road to Allison Ranch Road/La Barr Meadows Road
- Segment 4: Allison Ranch Road/La Barr Meadows Road to McKnight Way
In addition to the SR-49 Safety Assessment Report, Caltrans has also developed a series of four online videos highlighting key elements of the report.
