State and local transit officials and leaders on Wednesday, Oct. 4, kicked off a major freeway project along Interstate 605, designed to enhance the corridor from Los Alamitos to the San Gabriel Valley.
The $298.3 million, multi-phased effort — dubbed the Super 605 Freeway Enhancement Project — aims to improve overall ride quality along the route while bolstering safety for drivers and for state highway workers.
The new pavement itself will extend the life of the roadway from Long Beach to the San Gabriel Valley for up to 40 years, officials said.
The project is broken in into three segments.
In Segment 1, from Katella Avenue in Los Alamitos/Long Beach to Telegraph Road in Santa Fe Springs, Caltrans crews will replaced distressed pavement and concrete slabs, rehab 96 “lane miles” of pavement, upgrade curb ramps, replace signage and stripes and build in an in-roadway warning light system where the off-ramps from southbound I-605 meet the Spring St. bridge bicycle lanes. The project begins this fall and planned completion in early 2028.
In Segment 2, from the I-10 to the I-605 terminus north of I-210, similar improvements will be made, but upgrades will also include pedestrian upgrades at on- and off-ramps, and upgrades to six traffic signals. Construction will also include eight new vehicle maintenance pullouts, more than 12,000 linear feet of guardrail and the replacement of 27 overhead sign structures. It gets going in the fall and anticipated completion in fall 2026.
In Segment 3, Telegraph Road in Santa Fe Springs to I-10 is set to begin in spring 2024, and construction will include 93 lane miles of new pavement, upgrading more than 16,000 linear feet of guardrail and replacing 16 overhead sign structures. The project also includes 53 acres of landscaping and stormwater improvements to help prevent trash and other pollutants from draining into the San Gabriel River. Anticipated completion in early 2030, according to Caltrans.
