Abstract: A footbridge support is provided which is constructed of aluminum or other lightweight, weather resistant metal frame of bow truss design. Specifically, the footbridge support consists of dual bow truss frames, each supporting opposite side regions of the footbridge. The top rail of the truss frames is of curved configuration, with a given radius of curvature corresponding to the radius of curvature of the footbridge. The footbridge support also includes bottom members and transverse cross-members which connect the dual truss frames. A medial support member is positioned on the longitudinal midline of the footbridge and also corresponds to the radius of curvature of the footbridge to support the medial section of the footbridge. Decking is provided across the footbridge support, running from one of the dual truss frames to the other frame. With this footbridge support, longer and wider footbridges can be constructed with increased weight limits.
