A truck overturned on Interstate 80 in Oakland, spilling more than 40,000 sunflower seeds and blocking the first lane of the West Grand Ave. onramp.

California Highway Patrol tweeted a photo of the spill shortly after noon Thursday. The deluge of seeds — of the organic variety, CHP specified — covered the Downtown Oakland onramp.

Cleanup crews were working to clear the area, and just before 5 p.m., CHP said the onramp had reopened.
