The construction of the Dvorecký Bridge will include a new tram line measuring 361.4 meters. Construction of the line began in September 2022, with a total cost of CZK 1.45 billion. The line is scheduled to open in March 2026.

The tram line will provide two new main connections. Line 20 will run from Modřany and Braník via Smíchovské nádraží and on to Anděl, Malá Strana, and Dejvice. Line 21 will run from Barrandov to Podolí and on to Vinohrady.

As part of the construction of the new tram line, additional tram route adjustments will be made. Line 15 will replace Line 20 on the route to Barrandov. In Kotlářka, line 7 will replace line 15, and in Radlice, line 4—which will now operate all day—will provide a connection to the city center.

On Line 2, the long-awaited trams will finally appear on weekdays, though they will now continue from Charles Square to Nusle. Line 14 will temporarily leave the Prague tram network so that it can reappear in a completely new form after the opening of another major connection: the tram line on Wenceslas Square.
