Construction Supervision for New Trolleybus Line Project

This project involves the construction supervision of the new trolleybus line connecting Patrónka and Riviéra in Bratislava. The total length of the connection is approximately 6.38 km, with the Patrónka to Riviéra segment measuring about 3.05 km and the Riviéra to Patrónka segment about 3.33 km. The project requires the installation of new trolleybus overhead lines consisting of two tracks made from 100 mm2 copper wire. The line will start with a symmetrical switch on Karloveská Street and will continue along Botanická Street, where new shared overhead lines for trams and trolleybuses will be considered. Under the Lanfranconi Bridge, the trolleybus line will cross the existing tram line twice and proceed along Mlynská dolina Street to the intersection with Valašská Street, where a new switch will be established. A new turnoff will be created from Gaštanová Street into Pri Habánskom mlyne Street, where new overhead lines will be built up to the junction switch on Mlynská dolina Street. A symmetrical switch will also be established at the Mlynská dolina - Valašská intersection, allowing trolleybuses to continue along Mlynská dolina Street back to Botanická Street and then to Karloveská Street. Additionally, the existing transformer station in Karlova Ves will be upgraded from 9 to 13 feeding fields equipped with new technology and quick disconnects.
