Harbor Boulevard

Harbor Boulevard is a major thoroughfare in central Orange County.

Route description

It runs from Costa Mesa through Santa Ana, Garden Grove, Anaheim, Fullerton, La Habra and La Habra Heights before it turns into Fullerton Road in the unincorporated community of Rowland Heights just over the Los Angeles County line. It is the eastern border for the Disneyland Resort property and easily visible from the Monorail ride, although it is not visible while actually standing in the park due to Disneyland's berm. In reality, Harbor Blvd. is so close to that portion of Tomorrowland that the sirens of emergency vehicles that are traveling on it are quite audible to the guests in queues for Autopia or the Disneyland Railroad train ride.

The portion of Harbor Boulevard between La Palma Avenue in Anaheim to Whittier Boulevard in La Habra was part of the historical routing of U.S. Route 101, which was at the time the Coast Route from the Mexican Border to Oregon.

North Harbor Boulevard, where it rises from La Habra and passes over the Puente Hills, follows the historical route of the 1769 Portolà expedition, first Europeans to explore inland California.
