Protesters swarmed the Spring and Main street overpasses of the 101 Freeway, with police on standby to prevent them from trying to walk onto the highway.

Draped in Mexican and Salvadoran flags, roughly 1,000 demonstrators gathered near City Hall shortly before noon, blocking traffic at Spring and Temple streets.

Hundreds of demonstrators were marching the streets of Los Angeles on the same day as a nationwide movement protesting President Donald Trump's plans for mass deportations.
