The portion of 66th Street between Columbus Avenue and Central Park was renamed Tuesday after the Canadian-born anchorman who worked in the neighborhood and also lived nearby.
He even knew shopkeepers and street vendors in the neighborhood, said Mayor Michael Bloomberg.
"Peter spent decades speaking directly to each of us, with his face and that voice, and we'll walk down Peter Jennings Way, smile at the thought of an old friend and then continue on," Bloomberg said.
Jennings' wife, Kayce Freed, and two grown children, Elizabeth and Christopher Jennings, joined ABC News President David Westin, City Councilwoman Gale Brewer and the mayor for the dedication.
Jennings' family members said the gesture was especially meaningful to them and they hoped it would remind journalists and passers-by of his life and legacy.
