Harbor Blvd. & Adams Avenue Intersection Widening Project

OE provided construction management and inspection services to the City of Costa Mesa on the Harbor Boulevard & Adams Avenue project and was funded by Measure 2, State-Local Partnership Program, and Traffic Impact Fee funds. The project required adding a third dedicated left-turn lane eastbound on Adams Avenue, a second dedicated right-turn southbound on Harbor Boulevard, and lastly, extending the northbound left-turn lane on Harbor Boulevard. It consisted of major widening along the southerly side of Adams Avenue near the intersection. The project also included decorative crosswalks at the Harbor Boulevard—Adams Avenue intersection, traffic signal modifications, median alterations, landscaping, and a general grind and overlay of the roadway. Harbor Blvd. & Adams Avenue are two heavily used arterial roads that provide access to multiple businesses and shopping centers, and access to the Orange Coast College, as a result of the construction OE’s inspector provided the City with heavy traffic control. This project was identified in a Memorandum of Understanding (MOU) executed by OCTA, Costa Mesa, Fountain Valley, and Huntington Beach for the Garfield Avenue—Gisler Avenue Bridge over the Santa Ana River.
