The protesters left Hallidie Plaza in a long line that ran from the plaza to a crosswalk over the Embarcadero.

The tail of the protest was still leaving Hallidie Plaza, while the head of the protest had already crossed the Embarcadero.

A long line of protesters wound through the park behind Hallidie Plaza.

The long line of protesters continued through the park.

A video with the sounds and movement of the protest.

Part of the protest had already crossed the Embarcadero and was on its way toward Fisherman's Wharf.

A monitor stopped people from crossing when the light changed. And allowed them to cross when the crossing light became green.

The line of protesters waited on the sidewalk for the light to change, so they could cross the Embarcadero.

A sign held up by one of the protesters referenced the death of Mahsa Amini, which resulted in many protests inside Iran .

Another sign read, "Enough Is Enough."

The traffic light changed allowing another group of protesters to cross the Embarcadero.

While another group crossed the street, others had still not yet left the entry to the park.

A bus in support of the protest was parked on the Embarcadero and covered with signs and posters.
