The Most Dangerous Intersections in Costa Mesa

July 29, 2020

As part of our larger study of intersection-related collisions in Orange County, Aitken Aitken and Cohn wanted to provide drivers with resources for some of the major cities throughout the county.

During the study period, the city of Costa Mesa saw more than 2,000 intersection-related crashes – leading to nearly 2,400 injuries and 16 deaths.

While Costa Mesa only had one intersection in the top 50 county-wide, Gisler Avenue and Harbor Blvd, it none-the-less had several crossings with a relatively high volume of crashes and injuries.
