NEW YORK — Police started arresting demonstrators outside of Trump International Hotel in Columbus Circle Wednesday night.

"You are unlawfully in the roadway," the NYPD told protesters standing in the streets.

Police told protesters that if they voluntarily moved out of the street and onto the sidewalk, no charges would be placed against them.

Video shot by PIX11 showed NYPD officers putting several protesters in handcuffs and escorting them away.

Protesters yelled "shame on you" as police took fellow demonstrators away in handcuffs.

Hundreds of demonstrators showed no signs of slowing down by 11:15 p.m., yelling "we just started" as they stood across the street from the hotel.

Thousands of demonstrators brought Fifth Avenue to a standstill Wednesday night to protest Donald Trump being elected president of the United States.

Hundreds of protesters met at Union Square at 6 p.m. Another group of protesters met in Columbus Circle.

The two joined forces and by 8 p.m., the number of protesters grew to the thousands.

They carried rainbow flags and anti-Trump signs. One woman was seeing carrying a sign with photos of Trump and Adolf Hitler side by side saying "history is about to repeat."

Protesters walked up Fifth Avenue and began rallying in Columbus Circle.

Celebrities took to social media to show support for protesters.

"Hamilton: The Musical" creator Lin-Manuel Miranda said he would be in Union Square with protesters if he wasn't in Mexico.

If me & @Vegalteno weren't in Mexico, we'd be in Union Square with y'all. — Lin-Manuel Miranda (@Lin_Manuel) November 10, 2016

City officials tweeted that traffic delays should be expected throughout Manhattan including Union Square, Times Square and Columbus Circle. Drivers are encouraged to use alternate routes.

The midtown protest was just one of several across the country.

Protesters chanted anti-Trump slogans in front of Trump buildings in Chicago.

"Not my president, not today" was the chant heard and protests spanning from Boston to Los Angeles.

Trump was elected the 45th president of the United States in a stunning victory against Democrat Hillary Clinton.

Clinton conceded in a phone call to Trump early Wednesday morning.
