Sources: 5. Developments: 2. Authorities in Seville are evaluating several infrastructure projects to improve regional connectivity and public transport. Initial discussions focused on a proposed railway connection between the Santa Justa station and the airport, estimated to cost over 300 million euros. While a preferred route involving a tunnel under the A-4 highway was proposed to serve 2.1 million passengers, the Seville City Council and the Junta de Andalucía raised objections regarding its distance from business hubs and potential impacts on urban development. Efforts to enhance mobility have expanded to include broader metro and commuter rail strategies. Officials are considering the expansion of the Seville Metro through new lines, such as a metropolitan Line 2 to connect Sevilla Este with surrounding municipalities. Alternatively, planners are exploring the creation of an interchange between the metro and the Cercanías commuter rail system, specifically at El Higuerón Norte, to better integrate the Aljarafe region and La Rinconada into the metropolitan network. ## Timeline ### 2026-09-06: Seville explores metro expansion and rail interchanges Seville is evaluating metro expansions for Lines 2 and 3 alongside a proposed rail interchange at El Higuerón to improve connectivity between the province and the capital. 4 sources. https://clstr.news/cluster/seville-explores-metro-expansion-and-rail-interchanges ### 2026-08-25: Seville railway project to connect Santa Justa and airport faces 300 million euro debate Spain is reviewing two proposed railway routes to connect Seville's Santa Justa station and the airport, involving an investment of over 300 million euros amid local government opposition. 2 sources. https://clstr.news/cluster/seville-railway-project-to-connect-santa-justa-and-airport-faces-300-million-euro-debate --- Cite as: Seville regional transport infrastructure development.
