Abolitionist Action Central Coast organized a protest in front of the San Luis Obispo County Courthouse Sunday.
The event started outside of the courthouse and protesters marched throughout downtown San Luis Obispo.
Demonstrators say they support divesting funds from police and reallocating them to non-policing forms of community support and public safety.
"There's so many ways we can invest in our communities, invest in mental health, invest in education, invest in healthcare, invest in transportation. There's no reason why, especially in this county, anybody needs to be houseless," said Carmen Bouquin, of Abolitionist Action Central Coast.
The Cal Poly Students for Quality Education Club and the Cal Poly Black Student Union helped organize the protest.
CHP officers closed the Highway 101 on and off-ramps at Santa Rosa Street in case protesters marched on the freeway.
As of 7:30 p.m., police have reopened all streets and highways.
