The City of La Cañada Flintridge and Caltrans are working together to enhance safety and manage speeds along Angeles Crest Highway (ACH), from the I-210 freeway on/off ramps to the city limits. This webpage provides an overview of proposed design concepts, community meeting materials, and next steps for the project. Residents are encouraged to explore the concepts and share feedback to enhance safety along ACH corridor for motorists and pedestrians. Your input is essential to guide the City to select the improvements that reflect the community’s needs and priorities.
Design concepts
Improvements under consideration include:
- Traffic signal at Green Lane & Olive Lane
- Road diets (one lane in each direction)
- Raised medians
- Bike lanes
- Sidewalks

These design elements are based on community concerns raised during earlier surveys and studies conducted in 2022.
