Roadworks on the A-5 will disrupt travel in southwest Madrid this summer
Drivers using the A-5 this summer should expect lane closures, diversions, and narrowed lanes between Alcorcón y Navalcarnero. The Ministerio de Transportes y Movilidad Sostenible is starting a full resurfacing of a key stretch in the southwest of Madrid, between kilometres 10 and 36.7.
The project, awarded for 15.4 million euros, will affect a motorway heavily used by residents of Alcorcón, Móstoles, Arroyomolinos y Navalcarnero, as well as those leaving Madrid for Extremadura or the western area during summer weekends.
The first major disruptions will begin from 6 July heading towards Toledo. Between kilometres 13.4 and 14.2, the right shoulder, right lane, and part of the centre lane will be closed. Only the left lane and part of the centre lane will remain open, so traffic will be slower at this point.
The access from the junction at kilometre 13 towards the A-5 in the direction of Badajoz will also be closed. Drivers will need to use alternative routes via Avenida San Martín de Valdeiglesias and the M-50, a change that may particularly affect those who regularly travel in the area.
Towards Madrid, the works will also cause restrictions between kilometres 24.4 and 23.5. In this section, the shoulder and right lanes will be closed, while traffic will continue on the left lane and part of the centre lane. The service road will remain open, though it may experience heavier traffic at certain times.
These disruptions will be in place from 13 July to 26 August, as part of a work schedule that includes interventions at various points along the motorway. The works will mainly take place from Monday night to Friday midday, to reduce the impact on weekend travel.
Even so, the effects will be felt. July and August see less commuter traffic on some stretches, but also more holiday departures, getaways, and trips to second homes. Any reduction in lanes on the A-5 can lead to congestion at busy times.
Drivers in the area are advised to check traffic conditions before setting out, allow extra time, and pay attention to temporary signage. Lane changes, closed accesses, and the presence of machinery will require extra caution behind the wheel.
The resurfacing aims to improve safety and extend the lifespan of the road surface, a necessary intervention on a route that handles a high volume of daily traffic. For users, however, the cost will be less comfortable travel for several weeks.
The A-5 is one of the main gateways to the southwest of Madrid. This summer it will remain essential, but not as smooth as usual. For many drivers, the difference will be in planning each journey more carefully and accepting that some trips will take longer than expected.
