Istanbul Proposed Metro Lines — Planned Subway Routes and Future Underground Expansions

Istanbul – planned and proposed metro lines. Future underground routes and rapid transit expansion projects before construction begins.

Istanbul – metro and subway lines formally proposed or in active planning: future underground corridors announced, studied or included in urban transport master plans but not yet under construction. Shows where cities plan to extend rapid transit coverage — new orbital lines connecting suburbs without routing through the city centre, extensions to areas beyond the existing network and entirely new metro systems in cities currently without subway.

Istanbul – 167 proposed metro segments.
