Madrid faces two years without the Conde de Casal tunnel: how daily traffic will be affected
Madrid is entering a new phase of construction works that will affect thousands of daily journeys. The Conde de Casalcierra tunnel closes completely from this Friday and will not reopen until February 2027, disrupting one of the key access points in the southeast of the city.

Traffic will change from the early hours. Vehicles coming from the A-3 will lose entry capacity and many will have to divert above ground, while Plaza de Conde de Casal will absorb much of the tunnel’s usual flow.
The changes will also impact specific movements within the area. Some turns will be restricted and several usual routes will temporarily disappear, forcing residents and drivers to rethink their daily journeys for months.
Public transport is also affected. Several EMT lines are changing stops and routes to adapt to the works, including changes to lines connecting southeastern neighbourhoods with the centre of Madrid.
The project is part of the redevelopment of the future interchange and the connection with new transport infrastructure. The Ayuntamiento de Madrid maintains that, once the works are finished, the area will have greater capacity and reduced congestion.
But until then, the transformation will be very visible in daily routines. Traffic jams, route changes and more pressure on nearby streets will define the rhythm of one of the busiest entry and exit areas of Madrid.
UPD: The Ayuntamiento de Madrid has announced new overnight closures on the M-30 near Conde de Casal between the nights of 6 and 9 July. The disruptions will take place from 23:00 to 6:00 and will affect different carriageways and bypasses of the M-30, with diversions signposted via side or central carriageways depending on the night. The first intervention, from 6 to 7 July, will close the outer side carriageway between kilometre points 9.8 and 8.7, as well as the access ramp from the A-3 to the outer carriageway of the M-30. The Ayuntamiento recommends avoiding private vehicles in the area and checking traffic conditions before driving near Conde de Casal.
