Authorities had carefully planned for Saturday's event in Charlottesville, which past year became the scene of the Unite the Right rally's clash with the leftist Antifa protesters.
As reported past year, following Heyer's death, "about 1,000 people attended a memorial service for Heyer in Charlottesville".
The mother of Heather Heyer, the 32-year-old woman who was hit by a vehicle and killed last year, has also spoken publicly leading up to the anniversary.
Katrina Turner was at the rally a year ago and was nearly hit by the auto herself. Controversy also surrounded the planned removal of a statue of Confederate Gen. Robert E. Lee from a downtown park.
A 20-year-old man from Ohio, James Alex Fields Jr., was charged with second-degree murder in Heyer's death.
But a heavy police presence frustrated the activists, who called it an overcompensation for last year's events.
The group said it is "organizing marching bands, drummers, puppets, and vibrant displays of art and culture to show the diversity and power of united communities in the face of right-wing violence".
Citizens and media outlets seeking information related to current events in the Charlottesville area are encouraged to follow social media accounts for the City of Charlottesville and the University of Virginia.
Jason Kessler, one of the organizers of last year's Unite the Right rally, is again at the forefront of this year's event.
It's not that Fox never mentions neo-Nazis and white supremacists. We don't want well-wishers trampling other people's graves.
What are police doing about security?
President Trump - who a year ago faced widespread condemnation for blaming the violence on "both sides" - wrote on Twitter Saturday morning that the protests had "resulted in senseless death and division" and that he condemns "all types of racism and acts of violence".
By late Sunday afternoon, the barricades surrounding downtown Charlottesville, which some said had put the city under "martial law," were coming down, and the 700 Virginia State Police began heading home.
Newsham said no guns will be allowed near the rally sites, even if someone has a legal carry permit.
Besides some verbal confrontations between riot police and demonstrators, a rally in Charlottesville marking the anniversary of last year's deadly clash between right- and left-wing activists passed without any major incident.
As he said that, shouts could be heard down Fourth Street, and when asked what was going on, he said, "They're yelling at police".
