The subject of the project is the construction of a new trolleybus line on Výstupní Street in Ústí nad Labem. This line will connect the existing trolleybus lines in Krásný Březno and Dobětice. The new trolleybus line will be built as a two-track (in the direction of Krásná Březno - Dobětice), operation on it will be provided by partial trolleybuses. The project will be preceded by the modernization of the Krásné Březno transformer station (part of a separate application for support from the OPD).
