(BCN) -- Marchers wearing orange will cross the Golden Gate Bridge on Saturday afternoon to call for action on gun violence.

The march, part of Wear Orange Weekend, is one of about 750 events planned nationwide to honor the lives of those affected by gun violence and to demand prevention efforts.

Marchers will start from the San Francisco side of the bridge at noon. After a 1 p.m. program on the Marin side, the march will return to the San Francisco side.

The Wear Orange movement was inspired by events at a South Side Chicago high school in 2013, when friends of Hadiya Pendleton wore the color in her honor after the 15-year-old was gunned down -- just one week after performing in President Obama's second inaugural parade.

The campaign to fight gun violence is spearheaded by Everytown for Gun Safety. 

The march across the Golden Gate Bridge will be hosted by volunteers with California chapters of Moms Demand Action for Gun Sense in America and Students Demand Action -- both parts of Everytown for Gun Safety.

Event partners include Adamika Village, the Brady Campaign, the California Partnership to End Domestic Violence, Clif Bar, Youth Alive!, United Playaz, the Richmond Office of Neighborhood Safety, and San Francisco Suicide Prevention, Soldiers Against Violence Everywhere, the Taz Foundation, Women's March San Francisco.
