As hundreds of thousands gather in Washington, D.C. on Jan. 21 to protest the official start of Donald J. Trump's presidency, an estimated 20,000 will hit the streets in Portland to do the same.

On Friday, organizers of the sister march in Bridge City revealed the route their demonstration will take through a 44-block area of downtown.

The Portland Women's March begins at Tom McCall Waterfront Park on the south side of the Morrison Bridge at noon. Demonstrators will walk south on Naito Parkway, then turn right on Jefferson Street until turning right again on Fourth Avenue.

The march route.

The march will continue north on Fourth until demonstrators turn right on Pine Street and head back to the waterfront.

The march is preceded by a children's event that starts at 11 a.m., according to the event's Facebook page.

So far, 26,000 have RSVP'd for the event on Facebook. The march saw controversy earlier this month when the NAACP withdrew its support -- a move that pushed event organizers to make the Jan. 21 march more inclusive.

The march in D.C. is estimated to draw upwards of 200,000 demonstrators. The Washington Post reports that the city is expecting 1,200 buses for the event. Meanwhile, officials have received 200 bus permits for the inauguration.
