SR-57 Northbound Widening Project - Yorba Linda Blvd to Lambert Road

This project was completed in 2013.

This project provided an additional northbound (NB) lane on SR-57 and widened all existing lanes and the median shoulder to standard widths. The project was broken down into two segments, Orangethorpe Avenue to Yorba Linda Boulevard and Yorba Linda Boulevard to Lambert Road. This project length is approximately 2.5 miles.
