Signe infini, Metal sculpture at highway intersection in Ambérieux, France.
Signe infini is a large vertical infinity symbol constructed from welded metal and concrete, positioned at the intersection of the A46 and A6 highways. The structure rises prominently from the roadside and is visible from considerable distances as travelers approach the junction.
Marta Pan won a design competition in 1992 for this commissioned work, leading to the sculpture's installation in 1993 at the highway junction. The project emerged during a period when France was actively promoting contemporary art in transportation zones.
The sculpture marks a moment when artists began placing modern works directly into highway spaces, creating unexpected encounters with contemporary art during routine travel. This installation shows how public sculpture can become part of the landscape people pass through every day.
The sculpture is easily visible from both the A46 and A6 highways but cannot be accessed directly as it sits in the road divider. The best views come from driving past it or stopping at a nearby rest area for a closer look.
The infinity symbol was deliberately placed at a location of constant passage where thousands of travelers encounter it daily without necessarily noting it as art. This embedding into everyday commuting makes the work a quiet companion to journeys rather than a focal gallery piece.
