History in the MacArthur Maze

Historic route sign on Interstate 580 in Oakland

If you want to trace a historic route through the MacArthur Maze on westbound Interstate 580 in Oakland, this set of signs tells you how. Once exiting the maze in this direction, though, Interstate 580 and Interstate 80 are concurrent through Berkeley and Albany, so you could just as well have said "Use Interstate 580", at least for a few miles.
