Project Area

Los Angeles County Public Works is reconstructing approximately 2 miles of roadway along Altadena Drive and Washington Boulevard in the City of Pasadena and the Los Angeles County unincorporated community of Altadena.

This project will improve quality of life for residents and lessen wear and tear on vehicles. In addition, this project will also help to preserve natural resources by using recycled and in-place materials, resulting in cost savings and reduction in greenhouse gas, energy, and landfill deposition.

Construction is set to take approximately one year and anticipated project completion is scheduled for Summer 2025.
