Status

This project is in the Plan, Specification and Estimate (PS&E) phase, which includes final design updates and Environmental Revalidation, and is anticipated to end in late summer 2021. As part of this process, a PS&E report will be developed to account for refinements to elements of the SR-57/SR-60 Confluence Project FEIR, to quantify the cost implications for the current updates, and to guide construction for improvements.

Construction, led by the San Gabriel Valley Council of Governments (SGVCOG), is anticipated to begin the middle of 2022. Environmental Revalidation began in late 2018 construction to start in middle of 2022 and complete in late 2026. Project website and collateral information will be updated through construction.
