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 $565 million freeway improvement project was approved by Orange County voters in November 2006. The project is being built in three segments and includes numerous roadway, structural and operational improvements, including new general purpose lanes, improved intersections and widened ramps.
