The Community of Madrid has finalized the Arco Verde environmental project, a 262-kilometer network designed to improve natural connectivity across 25 municipalities. The infrastructure includes a 175-kilometer main ring and over 80 kilometers of branches that link regional parks, environmental education centers, and various natural areas.

In specific areas such as Arganda del Rey, authorities opted against direct interventions to preserve high-value river forests, instead providing access via the El Piul iron bridge to connect residents to routes leading toward San Fernando de Henares and other northern municipalities.
