SR-57 Northbound Improvement Project (Orangewood Ave. to Katella Ave.)

The California Department of Transportation (Caltrans), in cooperation with the Orange County Transportation Authority (OCTA), proposes to widen the northbound side of the State Route (SR) 57 freeway from 0.3 mile south of the Orangewood Avenue undercrossing (post mile [PM] 11.5) north to the Katella Avenue undercrossing (PM 12.5), a distance of approximately one mile. The SR 57 Northbound Improvement Project (Project) includes the construction of a 550-foot section of the fifth general purpose (GP) lane in the northbound direction of SR 57 through the Katella Avenue interchange, upgrades to the non-standard median and sight distances, and reconfiguration of the existing on- and off-ramps to improve operation between the Orangewood Avenue interchange and the Katella Avenue interchange. Caltrans is the lead agency under the National Environmental Policy Act (NEPA) and the California Environmental Quality Act (CEQA).

An Initial Study/Environmental Assessment (IS/EA) - Mitigated Negative Declaration(MND)/Finding of No Significant Impact (FONSI) has been prepared for this project and provides responses to Draft IS/EA comments received during the public circulation period. It compares the environmental impact evaluation and proposed avoidance, minimization and/or mitigation of potential impacts associated with all proposed Build Alternatives; and identifies the Preferred Alternative - Build Alternative 2.
