Closures and diversions on the M-50, A-4, A-5 and A-6 this summer

The works will be concentrated in July and August, months when daily traffic usually decreases, although outbound, return and weekend journeys increase. The aim is to take advantage of this period to carry out resurfacing, maintenance, waterproofing and road safety improvements.

The M-50 will be the most affected road. Between kilometres 17 and 45.9, works will take place in different phases, requiring full carriageway closures and diversions along alternative routes. For those who use this ring road daily, the schedule will be key.

On the right carriageway of the M-50, there will be closures from 6 to 17 July and from 20 to 24 July. Afterwards, works will move to the left carriageway, with disruptions from 27 to 31 July and from 3 to 14 August.

In addition, between the M-45 and the A-2, nightly closures are planned every day from 17 to 28 August. These works will take place between 21:00 and 6:00, a time slot chosen to reduce the impact, although it may affect those driving at night, working shifts or returning home late.

The Eje Culebro will also see works for much of the summer. On this section of the M-50, waterproofing and resurfacing will first affect the right carriageway from 6 to 31 July, then the left from 3 to 28 August, with diversions signposted as each phase progresses.

The disruptions will not be limited to the M-50. On the A-4, the stretch between the M-40 and the M-30 heading out of the city will be closed over the weekend of 10 to 12 July. Diversions will be via the M-45 and the M-40, so it’s advisable to check your route before heading south.

The A-5 will also face closures and lane narrowings. Between kilometres 13.9 and 14.2, there will be disruptions from 6 to 7 July, while between kilometres 24.3 and 23.5, works will continue from 13 July to 26 August. This motorway will be a sensitive point for those travelling between Madrid, Alcorcón, Móstoles y Navalcarnero.

On the A-6, works will be concentrated at night around Calle 30. From 6 July to 18 August, the main carriageway will be resurfaced, with night closures that may affect usual routes in and out via the northwest.

The DGT recommends checking traffic conditions before setting off. Variable message signs, the 011 phone line and official channels on X will provide updates on closures, delays and alternative routes.

For drivers, the key will be not to assume your usual route is available. A closed junction, an occupied lane or a temporary diversion can lengthen your journey, especially on getaway days, Friday afternoons or Sunday returns.

The works come at a time when many families take the opportunity to travel, visit second homes or move around the region more frequently. Although scheduled in summer to reduce inconvenience, the impact will be felt on access roads, ring roads and journeys between municipalities.

The M-50, in particular, has become a key part of metropolitan mobility. It connects residential areas, industrial estates, shopping centres and major motorways without passing through the centro de Madrid. That’s why any closure on this road is felt beyond the exact affected stretch.

The aim of the works is to improve the road surface, extend the lifespan of the roads and enhance safety. Before those benefits arrive, drivers will have to deal with cones, diversions and more unpredictable journey times.

Madrid doesn’t stop in summer, but its map changes. During July and August, driving on its major roads will require patience, up-to-date information and some flexibility to choose another route when the tarmac is being worked on.
