Everything you need to know about the March for Our Lives in L.A.

This Saturday, students from Marjory Stoneman Douglas High School in Parkland, Fla., have coordinated a series of nationwide marches to call for action to end gun violence and mass shootings in schools.

Events are planned in nearly 840 locations worldwide, including Los Angeles. The hub of march activity will be in Washington, D.C.

Here are some basics for the march in L.A. and elsewhere in Southern California:

Transportation: Driving downtown is likely to be difficult during the march. Spring Street will be closed between Temple and 7th streets, along with portions of Broadway and other adjacent streets as needed.

The March for Our Lives in Los Angeles will start at 6th and Spring streets and head toward Grand Park.

The main event: The main march will start with a rally and speaker program. Supporters will assemble at 9 a.m. at 6th and Spring. At 10 a.m., participants will begin marching along both Spring and Broadway toward City Hall and Grand Park.

The organization that was behind the L.A. Women’s March in January filed the permit for the downtown event. The permit application anticipates 50,000 participants.
