Pacific Infrastructure 405 Designers, a joint venture (JV) consisting of California-based Moffatt & Nichol with H.W. Lochner and Arup, is set to proceed with the planning and design of $1.9bn Southern California Freeway I-405 project.
The project is being delivered by the Orange County Transportation Authority (OCTA) in collaboration with Caltrans.
Pursuant to the contract, the design team will provide full engineering services for the OCTA's highway project.
In 2016, OCTA has selected OC 405 Partners, a JV between OHL USA and Astaldi Construction, to construct the design-build project.
Under the contract, the OC 405 Partners will improve 16 miles of I-405 between the SR-73 freeway in Costa Mesa and I-605 near the LA County line.
Furthermore, the JV will construct the 405 Express Lanes comprising the existing carpool lanes that will allow lone drivers to speed up their travel for a toll, and car-poolers may ride in the lanes for free.
Additionally, the project comprises construction of one regular lane in each direction from Euclid Street to I-605 and making improvements to freeway entrances, exits, and bridges.
Arup principal and project director Richard Prust said: "Arup, as part of Pacific Infrastructure 405 Designers, is extremely excited to be joining with OC 405 Partners and with OCTA and Caltrans to deliver this important project for the many communities of Orange County.
“We understand that designing and delivering this complex project will require complete collaboration between all parties, and that total dedication is critical to achieving OCTA's vision for the improvements to this important transportation corridor."
