San Diego Freeway I-405 Improvement Project

San Diego Freeway I-405 Improvement Project

Note: Extended Review. The I-405 Improvement Project proposes to widen the corridor by adding: one general purpose (GP) lane in each direction between Euclid Street and 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 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 proposed action would improve the freeway mainline and interchanges on I-405 in Orange and Los Angeles counties 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 to reduce congestion and improve lane continuity through the corridor.
