M-45 (Madrid) is an orbital high-capacity highway in the Community of Madrid forming a partial bypass to the south and east of the Madrid metropolitan area. Commissioned in the early 2000s, it was designed to relieve congestion on the M-30, M-40 and A-2 corridors and to serve satellite towns such as Getafe, Leganés, Alcorcón, and Alcobendas. Its planning and execution involved regional authorities including the Community of Madrid government and private concessionaires, with impacts on Comunidad de Madrid mobility, air quality discussions tied to European Union directives and debates among municipal administrations like Madrid (city), Alcalá de Henares, and Fuenlabrada.
The route begins near Mostoles at a junction with the A-5 corridor and arcs eastward passing close to Alcorcón, Leganés, and Getafe before intersecting radial axes serving Madrid (city), Parla, and Rivas-Vaciamadrid. It connects with highways such as the M-40, the M-50 via links, and the A-3 near Vicálvaro while skirting the Sierra de Guadarrama foothills. The alignment traverses municipal boundaries including Fuenlabrada, Getafe, Valdemoro, Rivas-Vaciamadrid, and San Sebastián de los Reyes and provides access to infrastructure nodes like Adolfo Suárez Madrid–Barajas Airport, industrial estates in Torrejón de Ardoz, and logistics parks serving IFEMA and Plenilunio Madrid. Service areas and interchanges are sited near urbanized zones and environmental areas such as the Parque Regional del Sureste.
Initial proposals for an outer bypass emerged amid late 20th-century growth in the Madrid metropolitan area as traffic on the M-30 and A-2 became chronically congested. Regional transport plans under administrations of the Community of Madrid in the 1990s commissioned studies involving consultancies, local councils including Getafe City Council and Leganés City Council, and national ministries such as the Ministry of Public Works. European funding frameworks and European Commission air quality directives influenced environmental impact assessments referencing sites like the Parque Regional del Sureste and Natura 2000 areas. Debates included stakeholders such as Comunidad de Madrid policymakers, opposition parties like the Spanish Socialist Workers' Party and the People's Party (Spain), and private concession companies negotiating toll and maintenance models.
Construction contracts were awarded to consortia including major firms active in Spanish infrastructure such as ACS (company), Ferrovial, and Sacyr along with specialized engineering consultancies. Works included earthworks, viaducts over the Guadalix basin, noise barriers near Fuenlabrada and Alcorcón, and drainage systems compliant with European Union directives. Upgrades over time incorporated smart-traffic systems interoperable with the Dirección General de Tráfico network and urban mobility initiatives from Madrid City Council. Expansion projects addressed junctions with the A-42 and reinforced bridges to accommodate freight traffic serving logistics hubs near Algete and Torrejón de Ardoz. Concession renewals involved negotiations with entities like Globalvia and financial institutions including Banco Santander and BBVA.
The M-45 serves commuters traveling between suburban municipalities such as Alcobendas, Parla, and Getafe and freight traffic to logistics centers near San Sebastián de los Reyes and Coslada. Traffic studies by the Dirección General de Tráfico and academic groups at the Complutense University of Madrid and the Polytechnic University of Madrid quantified peak flows, modal shifts from the Cercanías Madrid network and bus services by operators like EMT Madrid. Seasonal and event-driven variation links to activities at IFEMA and sporting events at venues such as the Wanda Metropolitano. Incident management coordinates with emergency services in Madrid (city), SUMMA 112, and provincial police including the Guardia Civil traffic unit.
Implementation provoked controversies over environmental effects on the Parque Regional del Sureste, air quality debates tied to European Union infringement procedures, and urban sprawl concerns raised by activists and NGOs such as Ecologistas en Acción. Political disputes involved the Community of Madrid administration and municipal governments including Móstoles and Alcorcón over land use, noise pollution, and compensation. Financial scrutiny examined toll models, public-private partnership terms involving firms like Abertis, budget allocations debated in the Assembly of Madrid, and audits by the Court of Auditors (Spain). Legal challenges reached administrative courts and featured participation by civic platforms and neighborhood associations in Getafe and Leganés.
Proposals for capacity improvements consider integrated mobility plans from the Community of Madrid, coordination with high-speed rail nodes like Madrid–Puerta de Atocha, and multimodal freight strategies linked to the Atlantic Corridor (TEN-T). Discussions include urban projects by Madrid City Council promoting public transport integration with Cercanías Madrid and bus rapid transit corridors, emissions reduction aligned with European Green Deal objectives, and smart infrastructure pilots involving companies like Indra. Potential extensions or link enhancements toward A-1 and A-4 corridors remain under feasibility evaluation by regional planners and research units at the Institute for Transportation Studies (Spain), with stakeholder input from municipal councils and logistics operators.
