Our Story

Today, nearly 360,000 motorists travel I-5 daily between the 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, OCTA and Caltrans are working together to implement the San Diego Freeway (I-5) Widening project from SR-73 to El Toro Road.

Located adjacent to the cities of Mission Viejo, Lake Forest, Laguna Hills and Laguna Niguel, this $540 million freeway improvement project was approved by Orange County voters in November 2006. Once construction begins, the project will be built in three segments and include numerous roadway, structural and operational improvements, some of which are highlighted below.
