On Saturdays and Sundays, from March to November, Paris shuts down some of the highways the run along the Seine. On the Right Bank the road is closed to motorized traffic from the Tuilleries to the Pont Charles De Gaulle. On the left bank, a portion of the Voie Expresse Rive Gauche is also closed, from near the Eiffel Tower to Bridge de la Concorde, where you can then switch to the right side. During July and August it may always closed to motorized traffic. Bikers share the highway with “rollers” and pedestrians. Since the views along the Seine are spectacular, this is a popular outing and something we try to do every Sunday we are in Paris.
