Madrid inaugurates the last underground passage of the Nudo Norte

22 months of works come to an end this Tuesday when, starting at midnight, vehicles begin to circulate through the underpass of the remodeled Nudo Norte de Madrid with which the City Council hopes to solve the usual traffic jams that are formed in the accesses to the capital

The Madrid alderman, José Luis Martínez Almeida, has detailed that the last access to reopen -that of the A-1 (Burgos road) in the direction of M-30/M-607 and towards Paseo de la Castellana- will cover this section . Only the new surface lane in the direction of Paseo de la Castellana will remain pending, which, as a deadline, will open to circulation on November 30, meeting the planned execution period, less than 24 months.

This new road, through which 27,000 vehicles will pass daily, will allow the direct connection of road traffic between the A-1 (Burgos road) and the M-11 (fairgrounds) to the M-30/Avenida de la Ilustracion and M -607 (Colmenar road).

Almeida stressed that this action eliminates an important black spot on the municipal road, relieving the traffic congestion that occurs, fundamentally, at rush hour in the morning and in the afternoon at the entrance to the city on the A-1 and M-40/M-11.

34,000 vehicles circulate daily through the Nudo Norte complex during the morning rush hour, from 8:00 a.m. to 9:00 a.m., and 33,800 vehicles in the afternoon rush hour, from 6:00 p.m. to 7:00 p.m. This road junction is used by more than 270,000 vehicles a day.

Almeida explained that the problem with this high-capacity road axis was the confluence of the M-30 and the M-607 (Colmenar Viejo dual carriageway), the Paseo de la Castellana, the M-11 and the A-1, being the section between this junction and the Manoteras junction one of those with the highest traffic intensity in Spain.

The remodeling project, with a final budget of 50 million euros (VAT included), has contemplated the adaptation works in all its connections to eliminate the four braids, which are the ones that caused the loss of capacity of the tracks and large traffic jams . The objective is to reduce traffic congestion at rush hour in this enclave of Madrid, since its influence affects the rest of the city.

For this, four structures have been built. Firstly, the direct connection viaduct between the Colmenar highway (M-607) and Paseo de la Castellana, which was completed in February this year; the direct connection underpass between the Castellana with the A-1 (highway to Burgos) and the M-11 (fairgrounds), which was completed in May 2022; the direct connection underpass between Paseo de la Castellana and Avenida de la ilustracion/M-30, opened in September.

Lastly, the one that the mayor visited today, the direct connection underpass between the A-1 (Burgos road) and the M-11 with the M-30 (Illustration avenue) and M-607 (Colmenar road) ).

The new underpass is 300 meters long and 8 meters wide, divided into two traffic lanes 3.50 meters wide each and two half-meter sidewalks. Attached to this passage is a gallery with a section of more than 40 square meters that houses two two-meter-diameter pressure pipes that form part of the Canal de Isabel II water supply network and that it has been necessary to set back in order to carry out this project. new step.

This underpass has been carried out with the highest standards in urban tunnel installations, with mechanical ventilation, fire detection, gas detection, access control and gauge systems, uninterruptible power supply, security lighting, emergency, as well as other security systems.

As in the other two underpasses, all these systems have been centralized through a Security and Control (ITS) system that will allow remote control of all equipment and signals from the Calle 30 Traffic Control Center through state-of-the-art technology that provides the new road with high safety.
