OCTA, in cooperation with Caltrans, is proposing improvements to the segment of SR-55 between I-405 and I-5. The project is currently in the environmental phase.
The Draft Environmental Document, also called the Proposed Mitigated Negative Declaration (MND) and Initial Study/Environmental Assessment (IS/EA) and other project documents are now available online at www.dot.ca.gov/dist12/DEA/SR55IMPROV and at several local libraries in the project area:
The Draft Environmental Document was released on Nov. 25, 2015, and is available for public review and comment until 5 p.m. Jan. 22, 2016.
Comments must be submitted in writing to Caltrans by 5 p.m., Jan. 22, 2016. Send comments to:

Currently, the SR-55 freeway has a total of five lanes in each direction, including the carpool lane, and provides enhanced traffic flow to approximately 295,000 motorists traveling the freeway each day. The SR-55 serves thousands of locals and visitors alike as the main route to get to work, home, popular beach communities and entertainment venues. The proposed improvements will allow residents, businesses and motorists to see enhancements to the SR-55 corridor that will increase capacity, improve traffic operations and improve mobility and reduce congestion.
Thanks to Measure M (Orange County’s half-cent transportation sales tax), $1.5 billion worth of improvements have been made to I-5 during the past 20 years. The Renewed Measure M (M2) Freeway program promises to earmark another $1 billion for SR-55 improvements in central and north Orange County.
The existing configuration of SR-55 corridor includes four general purpose lanes and one continuous-access high-occupancy vehicle (HOV) lane in each direction. The SR-55 project proposes to reduce congestion and increase freeway capacity for an existing four-mile stretch of the SR-55 in both the northbound and southbound directions, between I-405 and I-5. OCTA and Caltrans currently are conducting an environmental study which proposes to add new lanes and improve mobility for commuters within Orange County. There are currently four “build” alternatives as well as one “no-build” alternative that are being prepared for project analysis.
In addition to SR-55 mainline lane widening, additional improvements would include:
The Costa Mesa Freeway, State Route 55 (SR-55), was constructed in 1962 as a four-lane highway. Within the next 10 years, another lane was added in each direction.
In 1985, Orange County's first carpool lane was added to SR-55 between I-405 and SR-91 freeway. The freeway was also extended to 19th Street in Costa Mesa in the late 80s.
With the help of Measure M, Orange County's half cent sales tax for transportation improvements, along with additional state and federal dollars, SR-55 continued to change.
In late 1995, the freeway was widened between SR-22 and McFadden Avenue, and a direct carpool lane connector was added between I-5 and SR-55.
From 1996 to 2002, Caltrans and OCTA completed the addition of one lane in each direction between I-5 and SR-91.
The 55 Outreach Team is available to make a presentation to your neighborhood, organization or business. Feel free to contact us with your request, questions or comments by email or phone. You can also stay informed by visiting this page on a recurring basis or joining the project email list. We welcome your participation.
The environmental phase will include a public review period. Additional information regarding a public hearing/meeting will be posted as soon as the date and location are available.
