A day after President Donald Trump's inauguration, tens of thousands of people are gathering in Center City, Philadelphia, along the Ben Franklin Parkway for the Women's March on Philadelphia.
Here's everything you need to know if you're planning to attend -- or want to avoid the area:
When and Where Is the Women's March?
The event Saturday, Jan. 21, begins 10 a.m. at Logan Circle, which is between Love Park and the Art Museum of Philadelphia. The crowds will then march west on the parkway toward Eakins Oval.
They are expected to arrive at the oval over the next two hours, and then rally for a few hours until about 3 p.m., city officials have said.
What's the Purpose of the March?
March organizers said in a mission statement posted to their website that participants will "march in solidarity with marchers in Washington, DC for the Women’s March on Washington. We stand together in solidarity with our partners and children for the protection of our rights, our safety, our health, and our families."
"In the spirit of democracy and honoring the champions of human rights, dignity, and justice who have come before us, we join in diversity to show our presence in numbers too great to ignore.," the site says.
Who Is Organizing the March?
After Trump won the presidency, a retired attorney in Hawaii posted to Facebook about marching in Washington, The Washington Post reported. By the time Teresa Shook went to sleep, 40 women said they wanted to march. By the time she woke up, that number had ballooned to 10,000, the Post reported.
The march plans spread to over regions, and now marches are planned for cities and towns in all 50 states, according to organizers.
