UPDATED 8 a.m. Nov. 10: The election of Donald Trump to the presidency brought an unprecedented wave of protests Wednesday in urban areas including New York, Chicago, Boston, Berkeley, Portland, Austin and Los Angeles.

In Los Angeles, the march grew to thousands of protesters as the night wore on and 29 were arrested for blocking the 101 freeway through downtown, according to the Los Angeles Times. A large effigy of Trump’s head was burned.

More than 3,000 people had rsvp’ed on Facebook to an L.A. Emergency Rally set for 8 p.m. Wednesday at Los Angeles City Hall. Another rally is planned for 10 a.m. Saturday at Los Angeles’ MacArthur Park, sponsored by Union del Barrio.

In Berkeley, more than 1,000 high school students massed on the campus of UC Berkeley Wednesday, while UCLA and UC Irvine students protested as soon as the election was called Tuesday night.

Participants throughout the country carried signs reading “Love Trumps Hate,” “Fight Racism” and “Not My President.”

In New York, a crowd estimated at close to 10,000 protestors headed toward the Trump Tower and gathered at Union Square and Columbus Circle, while Chicago demonstrators also picked that city’s Trump Tower as the target of their anger at the election of a candidate with no previous political experience who has repeatedly expressed racist and sexist views.

The New York group carried Trump effigies and signs urging a protest at the Jan. 20 presidential inauguration in Washington, D.C.

“Have you ever seen a mess like this?” asked one person on Twitter. While a few fires broke out in Oakland, Calif. on Tuesday and Wednesday night, the protests Wednesday appeared to be largely peaceful with some tagging and other vandalism reported.
