I-605/SR-60 Interchange & Ramp Upgrades



The I-605 serves as one of the few major north-south interstate freeways in the greater Los Angeles Area of Southern California and the operational conditions along the project corridor are deteriorating. In order to improve local circulation and connectivity to interstate commerce, I-605 improvements are necessary.

D’Leon provided geometric engineering design support for the interchange and ramp improvements along the I-605 and State Route 60 Freeways. This is a Caltrans District 7/Los Angeles County Metropolitan Transportation Authority (Metro) sponsored project.


Our engineers provided engineering support which included the preparation of the project’s Project Approval/Environmental Document and used Caltrans Design Manuals and Specifications for all design-related documents. Our firm provided CADD design support using the latest engineering software to produce accurate and quality solutions.
