Super 605 Freeway Enhancements Project

Segment 3: Telegraph Road in Santa Fe Springs to I-10:

This project began construction in spring of 2024. It was allocated $201.1 million from the CTC in August ($184.2 million from IIJA, $16.9 million from SB 1). Construction is estimated to be $181.6 million. 

Improvements include rehabilitating pavement and concrete slabs. Construction will include 93 lane miles of new pavement, upgrading more than 16,000 linear feet of guardrail and replacing 16 overhead sign structures. In addition, the project includes 53 acres of landscaping and stormwater improvements to help prevent trash and other pollutants from draining into the San Gabriel River.

There are 78 (55-hour) extended weekend closures scheduled for this segment to expedite paving operations starting in the summer of 2025.

Anticipated completion of the project is in early 2030. Contractor: Meyers & Sons Construction.  

Background

The Super 605 corridor project will rehabilitate pavement on I-605 from Long Beach to the San Gabriel Valley. Construction, totaling $298.4 million, is funded with $273.3 million from the federal Infrastructure Investment and Jobs Act (IIJA), and more than $23.3 million from Senate Bill (SB) 1, the Road Repair and Accountability Act of 2017, and $1.9 million from SHOPP.

“Caltrans is aggressively upgrading and rebuilding our infrastructure in California, including pavement rehabilitation on major interstate routes that transport goods and connect local communities,” said Caltrans Director Tony Tavares. “The department and our federal partners are making a significant investment to rebuild and maintain our state transportation system.” 

Benefits

These upgrades will improve the overall ride quality, safety, and operational performance of the I-605 corridor for drivers and create a safer work environment for Caltrans workers by reducing the frequency and duration of pavement repairs. The new pavement will extend the service life of the roadway up to 40 years.

Total Programmed Project Costs

$298.4 million.
