Several hundred people marched across the bridge in a candelight vigil, hoping to send a message to legislators.
Attorney Norman Siegel says the rally was meant as a symbol of changing attitudes toward gun control.
He says those marching single file across the bridge hoped to inspire new gun laws after 20 small children and six adults were killed Dec. 14 at Sandy Hook Elementary School in Newtown, Conn.
The names of the dead were read aloud in the middle of the bridge.
And some of the demonstrators chanted "no more guns." One marcher, Melanie Waldman Lloyd, says she is appalled that people are allowed to own assault weapons. She has a 5-year-old child.
Some came from as far as away as France and Brazil, saying these shootings never happen back home.
"It's not allowed and people just don't think it's common to have guns at home," said Maggie Alves of Brazil. "That's not common, that's not our reality."
Siegel insisted the Newtown shootings have changed everything.
"It is time for New Yorkers and all Americans to call for action to stop gun violence that is eroding the fabric of America. Enough is enough," said Siegel.
