De brug (The bridge) is a 1928 Dutch documentary silent short film directed by Joris Ivens.

The view shifts to outside the train looking down at the harbor water far below, then to clouds of steam obscuring and revealing the bridge's steel structure.

The bridgemaster at the control console commands the raising of the central section, and the massive alignment grooves, pulleys, cables, and counterweights are all detailed in their steady synchronized operation until the bridge's maximum height of 38 meters is reached.

In 1927, Joris Ivens, along with writer Menno ter Braak and others, established the avant-garde film association Nederlandsche Filmliga (1927-1933).

[3] This enthusiasm, and the interest to make a film about a railway bridge, was also informed by Germaine Krull, whom Ivens had met during his studies in Berlin, and married in 1927, while she was working on her photographic portfolio Métal.
