This 5.7-mile project extends from Avenida Pico in San Clemente to San Juan Creek Road in San Juan Capistrano. The four-year, $230 million project will: 1) Add a carpool lane in both directions on I-5 between Avenida Pico and San Juan Creek Road 2) Improve the sight distance on the southbound horizontal curve north of PCH 3) Reconstruct the interchange at Avenida Pico, including widening the northbound Avenida Pico on-ramp to three lanes, and provide dual left-turn lanes to both northbound and southbound Avenida Pico on-ramps 4) Add soundwalls where needed.
Caltrans District 12 is currently reconstructing the Ortega Highway interchange at the I-5 freeway in San Juan Capistrano. Construction began in February 2013 and is expected to last through approximately fall 2015 as crews work to widen the Ortega Highway Bridge, reconstruct on- and off-ramps, construct a new northbound I-5 loop on-ramp from eastbound Ortega Highway as well as realign the Ortega Highway interchange. The project was initiated by Caltrans, OCTA and the City of San Juan Capistrano, as the solution to the "choke point", where significant delays and congestion occur along the Ortega Highway (SR-74) at the San Diego Freeway (I-5) interchange.
Today, nearly 360,000 motorists travel I-5 daily between San Joaquin Hills Toll Road (SR-73) and El Toro Road. Transportation planners expect traffic volumes to grow 25 percent by 2045. To address this travel demand, Caltrans in partnership with OCTA is implementing the San Diego Freeway (I-5) Widening project from SR-73 to El Toro Road to improve I-5 travel in southern Orange County.
Motorists frequently experience traffic congestion on the I-5 freeway between SR-55 and SR-57, and research indicates that delays likely will increase. According to recent studies, 390,000 motorists travel this route every day.
The Interstate 5 Freeway (I-5) through the cities of Irvine and Tustin is essential to Orange County’s mobility, economy and quality of life. It is a major commuter and commercial corridor, and serves as a “bridge” that connects Orange County to Los Angeles County and San Diego County. Today, this segment of I-5 is one of the most highly traveled and congested freeway corridors in the nation.
Local Interchange Upgrades
Caltrans has incorporated upgrades to interchanges within the scope of work for many of the I-5 South County Improvement Projects.
While not funded or managed by OCTA, the Santa Ana Freeway (I-5) South Corridor Improvement Project may impact Orange County commuters and travelers on the I-5. This page provides general background and relevant links to the main project pages.
Construction began in spring 2006 on the Santa Ana Freeway (I-5) Gateway Project and was completed in late 2010. The four-year project widened the remaining two miles of the Santa Ana Freeway (Interstate 5) in Orange County from the Riverside Freeway (State Route 91) to the Los Angeles County line. Landscaping is complete. The I-5 Gateway Project was the final link in the original Measure M's (Orange County's half-cent transportation sales tax) ambitious freeway improvement program.
Construction is now complete on the San Diego Freeway (I-5) at Camino Capistrano in San Juan Capistrano. The California Department of Transportation (Caltrans), in coordination with the Federal Highway Administration oversees the construction of the off-ramp widening and related improvements to address traffic backing up at the interchange on the freeway.
The California Department of Transportation (Caltrans), in cooperation with the Orange County Transportation Authority (OCTA), is proposing to widen the San Diego Freeway (I-405) between State Route 73 (SR-73) and Interstate 605 (I-605). The purpose of the proposed improvement is to improve travel conditions for work, recreation, school, and commerce by increasing freeway capacity, improving traffic and interchange operations, and enhancing road safety to meet state and federal standards. The I-405 Improvement Project is partially funded by Measure M Orange County’s half-cent sales tax for transportation improvements.
Interstate 405, also known as the San Diego Freeway, consists of 24 miles in Orange County and 48 miles in Los Angeles County. It serves as bypass route to I-5, and is a major local, regional and interregional travel route. The I-405 freeway also provides indirect and direct access to employment centers, recreational attractions, shopping malls, medical centers, universities, airports, and other land uses. Between I-5 and SR-55 and within the project limits, this segment of I-405 services the communities of southern Orange County, including the cities of Irvine and Costa Mesa.Currently, the I-405 freeway between I-5 and SR-55 is experiencing congestion and long traffic delays during peak traffic periods due to traffic demand exceeding capacity.
The Garden Grove Freeway (SR-22) travels mostly within the city of Garden Grove or along its border with neighboring Westminster.
The Costa Mesa Freeway, State Route 55 (SR-55), was originally constructed in 1962 as a four lane (two in each direction) highway. Within the next ten years one additional lane was added in each direction.
In 1985, Orange County's first carpool lane was added between the I-405 and the SR-91 freeway. The freeway was also extended to 19th Street in Costa Mesa in the late 80's.
With the help of Measure M, Orange County's half cent sales tax for transportation improvements, along with additional state and federal dollars, the face of the SR-55 continued to change.
For more than 50 years, the Orange Freeway (SR-57) has been integrally linked to Orange County's growth and legacy. During its five-decade history, this freeway has been uniquely intertwined with the evolution of many of the county's most notable attractions. Like the region and destinations it serves, the SR-57 is a classic landmark unto itself.
OCTA and the California Department of Transportation (Caltrans) District 12 are currently constructing a new, 4-mile westbound general purpose lane on State Route 91 between State Route 57 and Interstate 5.
The new westbound lane will increase capacity, improve driving operations and relieve traffic congestion along this key stretch of westbound SR-91.
In addition to building a new westbound general purpose lane, construction crews will also:
Located in northern Orange County, the Riverside Freeway (SR-91) is one of the region’s most vital, yet congested, commuter and commercial corridors. Everyday, more than 300,000 motorists drive it to get to work, school, home and other essential destinations. By 2035, more than 425,000 drivers are expected to travel the 91 daily. The 91 Freeway connects communities in Riverside County with employment centers in Orange County. It also serves as a “bridge” that links commercial trucks transporting good and products from the ports of Los Angeles and Long Beach to key local, regional and even national markets. Orange County visitors and locals alike also drive SR-91 to connect with world-class attractions and special events at Anaheim Stadium, Honda Center, Disneyland, Knott’s Berry Farm and other destinations. In short, SR-91 helps drive our economy and quality of life. This is why building “A Better 91” to keep the 91 Freeway moving, will help keep Orange County moving.
Starting in September 2016, OCTA, in partnership with Caltrans, will repave The 91 Express Lanes. Dubbed “The 91 Weekend Shift Project,” repaving is scheduled to occur over 10 consecutive weekends,
Caltrans District 12 and OCTA are currently in construction on the SR-91 Bypass Lane Project. This is the fourth in a series of improvement projects on the 91 Freeway in Orange County. Since December 2010, OCTA and Caltrans have added 18-lane miles to the 91 Freeway between Interstate 5 and State Route 241.
Caltrans District 12 and OCTA are expected to begin the Project Approval/Environmental Document (environmental review) phase on the SR-91 Widening Project between SR-57 and SR-55 in late 2014/early 2015. This proposed project will improve traffic flow and operations in both directions along SR-91 within the cities of Fullerton and Anaheim. This project is funded by OCTA’s Measure M Investment Plan – which was passed by nearly 70% of Orange County voters in 2006.
OCTA and its project partners are underway with construction on State Route 91 which will significantly improve travel operations along throughout Orange County. Travelers can expect temporary lane closures and need to follow the signs and stay alert.
The Riverside County Transportation Commission (RCTC) and project partners are making improvements to the 91 Freeway from Corona to Riverside. Construction on this major freeway improvement project began in early 2014 and new lanes are expected to open in 2017.
The Garden Grove Freeway (SR-22) travels mostly within the city of Garden Grove or along its border with neighboring Westminster. Just inside the Orange city limits, the freeway enters the congested Orange Crush interchange with the Santa Ana and Orange Freeways (Interstate 5 and State Route 57, respectively). It continues along the border of Orange and Santa Ana for 3 miles until terminating at the Costa Mesa Freeway (State Route 55).
Improve freeway access and arterial connections to I-605 serving the communities of Los Alamitos and Cypress.
The project will be coordinated with other planned improvements along SR-22 and I-405. Specific improvements will be subject to approved plans developed in cooperation with local jurisdictions and affected communities.
