PROJECT K
Segment: I-405, SR-73 to I-605
Status: Design-Build Underway - 62% Complete Contact: Rose Casey, Capital Projects • (714) 560-5729 Summary: OCTA and Caltrans are working together to widen I-405 by adding a general purpose lane and a second HOV lane (approximately 16 miles) in both directions to be combined with the existing HOV lane to provide a dual express lanes facility and improve the local interchanges along the corridor from SR-73 to I-605 through the cities of Costa Mesa, Fountain Valley, Garden Grove, Huntington Beach, Los Alamitos, Seal Beach, and Westminster.2 The final ED and PR were approved on June 15, 2015. Construction activities began on January 31, 2017. During the quarter, work continued on ROW acquisition, utility coordination, public outreach, installation of drainage systems, retaining walls, paving, and bridge construction. Design is substantially complete with the review of various design and construction submittals ongoing. OCTA’s toll lanes system integrator is under contract and working with OCTA and the design-builder. Construction on one-stage bridges (closed during construction) continued at Edinger Avenue, Edwards Street, Ward Street, and Warner Avenue. In April 2021, the Talbert Avenue bridge was completed and opened to traffic. Two-stage bridges (partially closed but allow throughway traffic during construction) at Bolsa Chica Road, Fairview Road, Goldenwest Street, and Westminster Boulevard are also underway. The Magnolia Street bridge was the first two-stage bridge to be completed and opened to traffic in May 2021. In addition to one- and two-stage bridges, construction to widen the existing freeway bridges on the Beach Boulevard/Bolsa Avenue railroad crossing, old Navy railroad crossing, and at the Harbor Boulevard and Santa Ana River bridges are ongoing. Construction of the Heil Street pedestrian overcrossing is also underway. Public outreach, through virtual neighborhood meetings, continues to be held to discuss construction activities. Substantial completion of the project is anticipated in late 2023.
2 The general purpose lane portion of the project is an M2 project and will be funded by a combination of local, state, and federal funds. The express lanes portion of the project is financed and paid for by those who choose to pay a toll and use the 405 Express Lanes.
Segment: I-405, I-5 to SR-55
Status: Environmental Phase Complete Contact: Rose Casey, Capital Projects • (714) 560-5729 Summary:This project studied the addition of a general purpose lane (approximately 8.5 miles) in both directions along I-405 between I-5 and SR-55 in the City of Irvine. The project development team reviewed the alternatives and public comments received during public circulation, and as a result of the effort, recommended adding one general purpose lane in each direction. The final ED and PR were approved on August 31, 2018. To ensure coordination with other projects planned for construction and to avoid unreasonable impacts to the public, this project is currently scheduled to be constructed beyond the Next 10 Plan timeframe.
