The Taguig City Integrated Terminal Exchange (TCITX), originally conceptualized as the South Integrated Transport System (ITS-South), is a proposed intermodal transport terminal in Arca South, Taguig. It is primarily a bus terminal for buses going to and from Southern Luzon, Visayas, and Mindanao but connected to the FTI station and the under-construction Metro Manila Subway and the North–South Commuter Railway, as well as the Southeast Metro Manila Expressway. Originally scheduled for completion by 2022, construction has yet to begin as pre-construction activities were temporarily suspended due to the ongoing COVID-19 pandemic, but it was lifted in July 2023.
