The Tel Aviv Metropolitan Area Mass-Transit System is a planned mass transit system for the Tel Aviv Metropolitan Area. The system will include different types of rapid transit like light rail (which will run underground in some areas), bus and more.

Work on the Red Line, the first in the project, started on September 21, 2011, following years of preparatory works and numerous delays.^[1] The Red line is planned to open in 2021. Both the Green and Purple lines will start construction in 2018 and are planned to open in 2024.^[2]
