The interruptions will occur in the direction of Madrid, specifically between 10:00 PM and 6:00 AM, primarily affecting the section between kilometers 25.500 and 23.800. These works are crucial for improving the capacity of one of the main routes connecting the northern region with the capital.

During the nights of Tuesday and Wednesday, there will be a total closure in the Madrid direction. Drivers in the area can use exit 24, diverting via Parque Avenue and the service road as an alternative. Subsequently, on Thursday, during the same nighttime hours, exit and merge ramp 24 in the Madrid direction will be closed to pave the weaving lane.

In addition to the nightly restrictions, lane narrowings are expected during the day on Tuesday and Wednesday due to the placement of metal barriers. These tasks could lead to temporary, sporadic closures. Exit ramp 24 from Tres Cantos towards Colmenar Viejo could also be affected during the day, although passage will be guaranteed for buses of the Regional Transport Consortium of Madrid in case of a complete closure.

Finally, on Thursday and Friday, work on merge ramp 25 towards Colmenar Viejo could cause narrowings and sporadic closures, depending on the progress of the on-site work.
