I-80 MacArthur Maze Vertical Clearance Project

Since the release of the draft environmental document, Caltrans has received comments, questions and concerns from approximately 200 members of the community, stakeholder groups, cities and other public agencies. After listening to this feedback, the decision has been made to pause the environmental process. After April 24, 2019, we will review all of the feedback we have received and will determine what additional information and analysis is needed to address the questions and concerns submitted. We will then recirculate a new draft environmental document with additional information for your comment. This webpage is where we will post updated information.
