Hamburg’s major traffic arteries are more than just entry and exit routes – they serve as city gateways, landmarks, urban living spaces, and at the same time, dividing barriers. The documentary Lifelines explores the role of these arterial roads in the cityscape: as the first point of arrival, as vibrant neighborhood centers, but also as transit spaces that connect and create boundaries. With striking visuals and fascinating insights into urban development, the film delves into the past, present, and possible future of these vital lifelines of the city.
