Diamond Springs Parkway Project

Welcome to the El Dorado County Diamond Springs Parkway project website.


The Diamond Springs Parkway is a future four-lane, divided roadway connecting Missouri Flat Road to State Route 49 (SR-49). The primary purpose of this project is to improve traffic safety and operations on portions of State Route 49 in the vicinity of Diamond Springs. The new road will provide parallel connection from SR-49 to US-50 that will relieve traffic congestion through the historic town of Diamond Springs. The project will also improve safety on Diamond Road/SR-49 by reducing residential driveway access with the provision of a new frontage road. The project is planned for completion in phases and is identified in the County Department of Transportation Adopted Capital Improvement Program. (See project numbers 72375 and 72334)
