San Diego Freeway (I-405) Improvement Project Supplemental Draft Environmental Impact Report/Environmental Impact Statement

The Public Comment period is from June 28, 2013 to August 12, 2013.



Busy Freeway

The Interstate 405 (I-405) Improvement Project proposes to widen the corridor by adding: one general purpose (GP) lane in each direction between Euclid Street and Interstate 605 (I-605); or two GP lanes in each direction between Brookhurst/Euclid Streets and I-605; or one GP lane between Euclid Street and I-605 and one tolled Express Lane in each direction between State Route 73 (SR-73) and State Route 22 (SR-22) east of I-405 to be managed jointly as a tolled Express Facility with two lanes in each direction between SR-73 and I-605. The tolled Express Facility would operate so that HOV2s would be tolled and HOV3+ would either be free or receive a discount. The proposed action would improve I-405 in Orange County for approximately 16 miles between 0.2-mile south of Bristol Street and 1.4 miles north of I-605, as well as portions of SR-22, SR-73, and I-605 by reducing congestion and improving lane continuity through the corridor. Please send your comments on this document to Smita Deshpande, Caltrans, at, no later than August 12, 2013.

This recirculation focuses on new traffic information for areas north of the limits of the proposed freeway capacity enhancement in Orange County. The traffic information addresses the traffic changes in the Long Beach area along SR-22/7th Street, I-405, and I-605, and at their local interchanges and nearby intersections due to the proposed build alternatives.
