### Transportation

After the [Ada Bridge](/wiki/Ada_Bridge "Ada Bridge") across the Sava was finished in 2012, a major *Radnička* [interchange](/wiki/Interchange_%28road%29 "Interchange (road)") was built above the river's mouth into the Čukarica Bay. Within the projects of the optimizing the bridge's function since then, there are some changes concerning the river itself. Within the scope of the construction of the new tram routes across the bridge, the already existing tram bridge across the Topčiderka will be removed but the pillars will be preserved and used for the new track bridge. The planned construction of the road connection of the bridge with Rakovica includes the relocation of the Topčiderka riverbed for 1 km (0\.62 mi), construction of a new bridge across the *Pere Velimirovića Steeet* in Rakovica's neighborhood of Kanarevo Brdo and reconstruction and widening of the *Bulevar patrijarha Pavla* which is designated to be the most important traffic route in this part of Belgrade. Stretching along the valley of the river, it is envisioned as the main transit corridor which would connect the [European route E75](/wiki/European_route_E75 "European route E75") (Belgrade\-[Niš](/wiki/Ni%C5%A1 "Niš") highway), [New Belgrade](/wiki/New_Belgrade "New Belgrade"), Ada Bridge, *Patrijarha Dimitrija* Street, [Ibar Highway](/wiki/Ibar_Highway "Ibar Highway"), Kružni put and the [Belgrade bypass](/wiki/Belgrade_bypass "Belgrade bypass"). As of January 2018, the timeline of the entire project is unknown, as only a partial request for tendering was announced.

Due to the road, bridge and interchange construction, the section of the river was moved  to the east. As this is the location where the stream of Kaljavi Potok flows into the Topčiderka, its mouth was also moved while the final  of its flow were conducted underground, through the pipes. The new bridge is  long and  wide, with three lanes in each direction. The works on the relocation of the river began on 1 March 2018, and were finished by August 2019\. The bridge became operational on 22 March 2019\. Further widening of the boulevard along the river began in the late summer of 2019, and was set to finish in the spring of 2021, but the deadline was moved to September 2021, then to May 2022, and to October 2022, before the deadline was moved for the summer of 2024\. In October 2023 mayor [Aleksandar Šapić](/wiki/Aleksandar_%C5%A0api%C4%87 "Aleksandar Šapić") blamed the [Russian invasion of Ukraine](/wiki/Russian_invasion_of_Ukraine "Russian invasion of Ukraine") for further delays.


When were the works on relocating the river started?
