Project Overview

OCTA and Caltrans are improving Northbound SR-57 between Orangewood Avenue and Katella Avenue to address heavy congestion and improve regional circulation of goods and services. As a vital link for 120,000 daily motorists, this segment currently serves as a primary access point for major employment, academic, and entertainment hubs in the cities of Anaheim and Orange. The corridor presently consists of four general-purpose lanes and one carpool lane, which often experiences bottlenecks due to high-volume merging. This project will add a new general-purpose lane and improve auxiliary lanes for smoother merging and exiting within the project limits.
