The Troja Bridge (Czech: Trojský most) is a prominent bowstring arch bridge spanning the Vltava river in Prague, Czech Republic. Designed to accommodate road traffic, pedestrians, and most notably the city's tram network, it was completed in 2014 as part of the Blanka Tunnel Complex project. The bridge is characterized by its slender white arch and dense network of hangers, which have made it a modern architectural landmark in the Holešovice and Troja districts.

Constructed primarily from steel and concrete, the bridge serves as a vital transit link for Prague's integrated transport system. Its design was the result of an architectural competition, emphasizing a low-profile silhouette that does not obstruct the historic skyline of the city. The structure is maintained by the Technical Road Administration of the City of Prague, ensuring its longevity as a key piece of European urban infrastructure.
