Alberto Ruiz-Gallardón, former mayor, was the first to present this idea, taken up by the current councilor, José Luis Martínez-Almeida, after years of complaints from neighbors affected by highway noise. If all goes as planned, this road will become an urban corridor next year.

Parque Ventas will also join two neighborhoods separated by 16 lanes through which, before the start of the work, 1.4 million vehicles circulated every day.

In addition, the new neighborhoods in the southeast will see the light of day next year, with Madrid Nuevo Norte, Los Berrocales and Valdecarros in their sights. In the latter, the urbanization of the first three of the eight stages of the project should be completed in 2026.

In Madrid Nuevo Norte, the first urbanization works in Las Tablas Oeste will begin at second quarter 2026so that the first housing units will be delivered in 2029.

Changes in the suburbs

One of the most anticipated openings this year was that of metro line 6, which reopened its doors to users on December 20 with its renovated infrastructure. After two hundred days of work and with the alternative of the Special Bus Service, the line in both directions is operational again. The reopening of the section between Moncloa and Legazpi, interrupted since September 6, has been brought forward by eleven days.
