Transportation
The boulevards are, of course, city streets and open to vehicular traffic. They do not constitute an expressway or limited-access motorway in the fashion of the Boulevard Périphérique; the speed limit on the boulevards is generally 50 km/h.
There are also bus lanes separated from the normal lanes of traffic, and a bicycle path on the sidewalk has been installed. The Paris Tramway Line 3 (Ile-de-France) follows the boulevards of the marshals along the southern edge of the city.
