Climate protesters shut down multiple key D.C. intersections Monday—and they want to do it again on Friday morning.

In a text message to supporters on Monday afternoon, organizers of #ShutDownDC said, “Friday we are going to hit the streets again.” They also asked for donations to keep the movement going.

While details are not yet set in stone, it appears the protesters will try to close intersections again Friday at 7 a.m.

Organizers say they managed to block 22 intersections on Monday for at least a little bit of time. Some intersections, like 16th and K St. NW, were closed for more than three hours during the morning rush hour.

Police arrested at least 26 protesters for blocking traffic.

Demonstrators wrote on their website that they aimed “to disrupt the systems that created and perpetuate the climate crisis,” urging “climate rebels” to bring the “whole city to a gridlocked standstill.” Monday’s blockades were timed to coincide with the United Nations Climate Action Summit in New York.

“Shutting down DC won’t solve the climate crisis alone. What we can do is demonstrate that people from a broad range of backgrounds are no longer willing to continue with business-as-usual,” the Shut Down D.C. website reads.

Friday’s protest will mark the end of a global week of action on climate change.
