The transport of the 340-ton boulder at the center of Michael Heizer's art display made headlines in March.
LACMA officials announced the public will be able to view "Levitated Mass" starting June 24. The boulder will be positioned to appear as if it's floating.
The massive rock was taken from a Riverside quarry and hauled more than 100 miles through 22 cities. Residents of those cities will be granted free admission the week the exhibit opens.
Officials haven't said if Heizer plans to attend the unveiling. The reclusive artist has been quietly overseeing the rock's installation.
