Eco visual - la rama (the branch) - The Rambla of Montevideo is an avenue that goes all along the coastline of Montevideo, Uruguay, and also the longest continuous sidewalk in the world. At a length of over 22.2 uninterrupted kilometres (13.7 mi), the promenade runs along the Río de la Plata and continues down the entire coast of Montevideo. Since all the southern departments of Uruguay are against either the Río de la Plata or the Atlantic Ocean, they all have ramblas as well. The Rambla is an integral part of Montevidean identity and has been proposed as a World Heritage site.
