It is the brainchild of Mayor Anne Hidalgo and is designed to lower excessively high air pollution.
The first of the monthly pedestrian-only days was declared a convincing success by tourists and residents of the city who were able to enjoy the 2km long (1.2-mile) avenue leading to the Arc de Triomphe.
Pedestrians were able to watch a variety of street performers on the famous thoroughfare

"It's magnificent," AFP news agency reported city resident Roger, 67, who lives just off the Champs-Elysees, as saying.
"All of Paris should be like this," he said.
Paris city authorities have taken various measures to reduce pollution levels, including rental bicycles, cycling paths and a fleet of electric cars
