There will be increased truck traffic in the project area for approximately two months to off-haul the stockpiles located across from the Palace of Fine Arts and adjacent to Sports Basement. New material will subsequently be delivered to the same stockpile locations. Trucks are also bringing in excavated material from the Cathedral Hill project to use as backfill on the southern side of the Main Post Tunnels.
