The viaduct contains LED lighting and provides itself with energy by means of the solar tree. This artificial tree, with solar panels as leaves, generates enough energy for the LEDs on the bridge. The design of the solar tree consists of elements that can be found in the viaduct itself. The fence of the viaduct contains the triangular details that match the leaves of the tree. The curved posts of the solar tree refer to the handrails of the viaduct. So, these objects are two stand-alone objects that go well together in the environment. Real eye-catchers!
