The /*Long Life Asphalt Concrete Pavement Rehabilitation/* project began in 2001 and still has another five years to go.
Crews are using a special blend of asphalt that may serve as a model for freeway construction.
At some parts of the freeway, fiber optic lines will be installed underneath the pavement for traffic data collection and traffic management, according to Caltrans.
The first phase of the project was completed in December 2004 and included the 710 from Pacific Coast Highway to the 405.
The third and final phase is scheduled to begin in the spring of 2012. It will focus on the 10 freeway.
