Description:

The California Department of Transportation (Caltrans) proposes the MacArthur Maze Vertical Clearance Project (project or proposed action) to increase the vertical clearances at three locations within the MacArthur Maze Interchange (MacArthur Maze or Maze) in the City of Oakland, Alameda County. Two of the locations are along the connector from westbound (WB) Interstate 80 (I-80) to southbound (SB) Interstate 880 (I-880), as it crosses below the WB and eastbound (EB) Interstate 580 (I-580) overcrossings. The third location is along the connector from WB I-80 to EB I-580 as it crosses below the connector from WB I-580 to WB I-80. The existing vertical clearance at these three locations does not meet the current Caltrans standard of 16 feet 6 inches and impedes the safe and efficient movement of oversized vehicles and loads through the Maze. The project is proposed to increase the vertical clearance of the structures in the Maze to allow for more efficient travel of oversized vehicles.
