South Orange County Traffic Relief

System Map

Orange County has a robust transportation network consisting of freeways, toll roads, bicycle paths, bus transit, railways and walking paths. Since 1981, State Route 241 has been on Orange County's Master Plan of Arterial Highways to accommodate planned growth in South Orange County, alleviate traffic congestion on Interstate 5 (I-5) and provide traffic redundancy in the area in case of emergency. 

However, traffic on I-5 in South Orange County is more congested than ever -- especially on weekends -- and it’s anticipated to get worse. Because there are currently no major alternative route to I-5, whenever traffic is severely congested due to weekend or holiday traffic or if there is an incident or construction on I-5, traffic spills onto the local streets of San Clemente, Dana Point and San Juan Capistrano -- completely clogging local city roadways as drivers try to find a way around the gridlock to their destination.

With the county’s population expected to increase by more than 400,000 residents by 2035; 14,000 new homes being built in Rancho Mission Viejo over the next decade; and traffic projected to increase in South Orange County by 60 percent by 2035, we must work together to identify solutions that will relieve the excessive traffic congestion on I-5.

The Public Process

In 2015, a South Orange County Community Ascertainment Study identified high levels of agreement amongst stakeholders in the region that there is a growing traffic problem that people expect their elected officials and public agencies to fix. There is undoubtedly excessive I-5 traffic during the morning and evening commute times, on weekends, and whenever there is an accident or incident that impacts an I-5 traffic lane. Research has concluded that this severe congestion is gravely impacting quality of life for South Orange County families, residents, business owners, and commuters.

Get Moving OC, is a result of the recommendations of the Community Ascertainment Study and is the first part in a series of next steps led by the Transportation Corridor Agencies (TCA), along with participation from multiple transportation planning agencies throughout the region, to address transportation mobility concerns in South Orange County. These agencies include Caltrans and the Orange County Transportation Authority (OCTA). Through this process several public forums have been held across South Orange County to solicit input from the public and local elected officials for their ideas on how we can relieve traffic across the region. So far, 18 ideas have been received.  As required by state and federal laws, TCA is analyzing, studying, and screening the 18 transportation solution ideas proposed by the public to determine their benefits, costs and impacts to find a balanced solution to solve our region’s traffic problem. We encourage you to participate and remain engaged in this process every step of the way to ensure your community’s needs and priorities are considered.

Settlement with the Environmental Community

In 2008, the California Coastal Commission denied a key permit for a previously proposed project known as State Route 241 Foothill-South.

On Thursday, November 10, 2016, TCA announced the settlement of five lawsuits regarding the previously proposed projects known as State Route 241 Foothill-South and Tesoro Extension. TCA is pleased to join more than a dozen environmental organizations in this unprecedented outcome, underscoring the collaboration between TCA’s leadership and the leaders of the environmental community. It is with this collaboration and framework, that TCA will move forward to review alternative solutions for solving the regional traffic problem in a manner that protects our most environmentally and culturally sensitive lands.
