The German "Brücke" is a feminine noun and therefore "Die Brücke" the correct title.
In German, nouns for things can have a gender ("der Mond", "die Sonne") while nouns for living creatures can also be neutral ("das Kind"). There are also some basic rules for this and very many nouns are to be considered again separately. Therefore, those who want to learn German are advised to always memorize nouns with their respective gender.
