During the coronavirus pandemic, construction is continuing on major OCTA construction projects and those in partnership with Caltrans. Public transportation projects are considered essential by the state.

Projects include the I-405 Improvement Project, OC Streetcar, I-5 South (SR-73 to El Toro Road) and I-5 Central (SR-57 to SR-55).

OCTA is coordinating with Caltrans and contractors to accelerate construction projects where possible. As people stay home to reduce the spread of the coronavirus, traffic on local freeways has been reduced by approximately 60 percent, allowing daytime lane closures and extended overnight closures.
