ORANGE COUNTY, CA—The Orange County Transportation Authority, in partnership with Caltrans, has broken ground on the I-405 improvement project, which targets a 16-mile stretch of freeway between Costa Mesa and the Los Angeles County line. The $1.9-billion project will add one regular lane in each direction between Euclid St. and I-605, as promised to voters through Measure M, Orange County's half-cent sales tax for transportation improvements.
The project also adds a second lane in each direction, which, combined with the existing carpool lanes, will create the 405 express lanes. This is the largest highway project currently under construction in California and the largest in OCTA's history.
In addition to constructing the new lanes, the project will build, widen or replace more than 18 bridges and improve freeway access and traffic on local streets—work that is critical to accommodate expected growth in Orange County and throughout the region. Traffic on I-405 is anticipated to grow 30% by 2040.
