The Hofbogen in Rotterdam, a 1.9 km railway viaduct built in the early 20th century, is set to be transformed from a forgotten piece of infrastructure into a lively, sustainable urban environment focusing on culture, business, and community. Key to this redevelopment is the construction of a new bridge across the A20 highway, enhancing connectivity and promoting environmentally friendly transportation options. The project aims to create a green technology and innovation cluster, contributing to the city's sustainability while fostering social interaction through cultural and social activities.
The construction of a new bridge starts with the assembly of prefabricated arches using specialized formwork, followed by their placement as the main structural elements. Subsequent steps include welding staples and roof elements to these arches for stability, and finally installing the prefab deck that supports pedestrian and cyclist traffic, completing the bridge for use.
The bridge is constructed using prefabricated elements with arches as load-bearing structures, welded together in stages to ensure uniformity, safety, and aesthetic appeal, culminating in a securely attached deck for user safety.
