Project Title - SR-57/SR-60 Confluence at Grand Avenue Project (57/60 interchange)
Project Location - Cities of Industry and Diamond Bar in Los Angeles County
Project Description - The California Department of Transportation (Caltrans) in cooperation with the City of Industry will prepare an Environmental Impact Report (EIR)/Environmental Assessment (AE) on a proposal for constructing freeway improvements to the State Route 57 (SR-57/Orange Freeway))/State Route 60 (SR-60/Pomona Freeway)) Confluence at the Grand Avenue interchange in Los Angeles County, California. The project consists of the reconfiguration of the approximately 2.5 confluence of SR-57 and SR-60, which includes the addition of auxiliary lanes and associated on-ramp/off-ramp reconfiguration. A Project Study Report (PSR) for the project was completed in March 2009.
Purpose – To improve traffic operation on Grand Avenue from Golden Springs Drive to the interchange at SR-60 (Pomona), increase capacity at the Grand Avenue Interchange, improve traffic operation on the freeway mainline, reduce traffic weaving and increase weaving distance and improve safety.
