> As part of the Federal government’s Coronavirus Guidance for America, transportation infrastructure is considered an “Essential Critical Infrastructure.” > Additionally, transit capital projects are not subject to the State of California’s Stay at Home order, therefore Metro construction projects continue to progress. Updated personal protective equipment (PPE)

> Construction activities continue to progress on all active Metro projects, including the Crenshaw/LAX, Purple Line Extension and Regional Connector Transit Projects. > Due to reduced traffic conditions during the Stay at Home orders, local jurisdictions are allowing the Agency to work through “peak hours” on a case by case basis. > Metro’s contractors are following safety precautions during the pandemic, including implementing social distancing when applicable and the use of masks and other PPE.
