The Torrelaguna tunnel will experience traffic closures in both directions from Monday, September 28, due to sanitation network renovation works.

Sanitation network renovation works on Torrelaguna street will necessitate new traffic closures and changes in the area. Starting Monday, September 28, the Torrelaguna tunnel will be closed to traffic in both directions for the duration of the works.
During this period, access to Ferrocarril and Marqués de Santillana streets will be maintained from Parque street. Diversions and closures will be clearly indicated with advance informational signs for drivers.
The Local Police advise drivers to use alternative routes, follow instructions, and exercise extreme caution in the area. Circulation on nearby streets will also be modified as the works progress, which are expected to last several weeks.

We apologize for any inconvenience and thank you for your understanding and cooperation.
