Interstate 405 between SR-73 and I-605

The following Draft Environmental Impact Statement/Environmental Impact Report proposed for the Interstate 405 between SR-73 and 1-605 has been provided for reference. This document is no longer accepting public comments. However, please feel free to provide your comments under the Supplement Draft EIR/EIS.

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.
