The subject of the project is the construction of a new tram line in the territory of the City of Prague with a length of about 1.7 km connected to the existing tram loop Levský to the new Úvraťová finite Libuš. Four new stops will be built on the new section of the tram line. The line will be terminated by the collapse of the future Libuš metro station on line D. In the future, it will follow the project Phase 2, in which a fully-fledged tramway will be built in the area.
