The Gauja National Park Footbridge is a well-planned structure located at the entrance to Gauja National Park. It is designed to create a connection between the artificial landscape of the motorway and the natural beauty of the park. The concept is inspired by the simple act of crossing a creek using a log, which emphasizes the bridge’s role in facilitating movement and transition. By integrating functional needs with cultural significance, the design engages visitors and enhances their experience with the environment.

Structural Design

The footbridge features a curved steel box girder structure, which is supported by internal diaphragms and longitudinal stiffeners. This design results in three spans: a large central span and two smaller side spans. The engineering approach ensures that the structure is both efficient and economical, showing a careful balance between functionality and aesthetic considerations.

User Experience

The deck is designed with varying widths that range from 2.5 to 4.0 meters, providing an open feeling for those crossing. These dimensions cater to expected pedestrian traffic and create a welcoming atmosphere for visitors. The design enhances the interaction between people and the surrounding landscape, making the experience of crossing the bridge more enjoyable and meaningful.

Material Engagement

Weathering steel is the primary material used in building the footbridge. This type of steel is known for its durability and its ability to develop a protective rust layer over time. This feature helps the bridge blend into its environment. The barriers, made of horizontal steel plates, not only provide safety but also align well with the overall design, ensuring that the structure does not obstruct the views of the park.

The details of the footbridge highlight a focus on clear forms and functionality. The careful connections and the overall shape illustrate the craftsmanship involved in its construction. This design resonates with the natural setting while serving the practical needs of those who travel through the park.
