At its meeting on March 14, the OCTA Board of Directors voted to enter into cooperative agreements with the cities of Costa Mesa, Fountain Valley, Huntington Beach, and Westminster to provide city services required during the design-build implementation of the Interstate 405 (I-405) Improvement Project.
Because the project includes improvements to city-owned and operated streets and will impact some city traffic facilities, a cooperative agreement with each of the I-405 corridor cities is necessary to define the roles and responsibilities of each agency during the project’s implementation.
OCTA will use a design-build delivery method for the procurement, design, and construction of the project. Design-build is a process that allows for project design and construction to occur simultaneously. One contractor is hired to perform both functions, which increases the speed by which a project can be delivered.
The I-405 Improvement Project will add one general purpose lane in each direction from Euclid Street to Interstate 605 (I-605) and add an express lane in each direction. The new express lane, along with the existing high-occupancy vehicle lane, would become dual express toll lanes in each direction on I-405 from State Route 73 to I-605.
