The northwest sierra, awaiting the layout

The M-505 is one of the main access roads to the northwest sierra from the metropolitan crown and supports daily and weekend mobility traffic. The tender is added to the series of bypass studies that the Department has been calling for in recent months, including those for the M-322 in Colmenar de Oreja and the M-226 and M-235 in Los Santos de la Humosa, all with sections of about 3 kilometers and a term of 20 months.

The result of this contract does not yet execute any work: it defines and compares layout alternatives and evaluates their environmental impact, an essential preliminary step so that the project can be submitted for public information. For the residents of Galapagar and surrounding municipalities, the study will determine if the future bypass diverts through traffic from the urban center and under what conditions. The 20-month period places the conclusion of the document, in the best-case scenario, at the end of 2028.
