The Leblanc portion of the name comes from the name of a street in Laval that was expropriated to build the autoroute. That street was named after Alpha Leblanc, a local landowner. Portions of that street remain on both sides of the autoroute.
In 2000, a proposition to rename the bridge after the late Pietro Rizzuto was initially approved, then rejected by the Commission de Toponymie du Québec, which ruled that the name Papineau-Leblanc was already entrenched in local culture and non-controversial. Most locals simply refer to this bridge as Papineau.
