The bridge is a spatial structure made of wooden and wood-glued elements. The main forming element is an oval frame. 13 such frames are installed one after the other along the arcuate axis of the bridge, the frames are installed in such a way that at the place where the bridge supports are located the frames are horizontally oriented and in the middle of the bridge they are vertically oriented. This makes the structure more stable and in the place of the largest deflection of the bridge, namely in the middle, increases the vertical section of the bridge structure. Also, the frames from the supports to the center of the bridge smoothly change their position from horizontal to vertical, which creates the effect of smooth flow of forms when facing the bridge with wooden slats. The frames are interconnected with wooden beams. The outer outline of each frame consists of 16 faces, so that when moving from one frame to another, these faces rotate at a certain angle around the central axis of the frame, which, when lined with slats, creates the effect of twisting the lining along the bridge axis. Strips of facing in the upper part of the bridge are made of glass, which protects pedestrians from precipitation. The canvas of the bridge has an arcuate shape with a small boom, which makes it possible to raise the lower point of the bridge above 4.5 meters above the road for passing heavy vehicles. Also, this form of the bridge has a small elevation angle, which, together with two railings on both sides of the bridge, facilitates the movement of slow-moving groups of people along it. The supporting elements of the bridge are slabs made of reinforced concrete. These slabs, in turn, are grillage of reinforced concrete piles, driven in places of bridge piers. Wooden structures of the bridge are attached to the metal embedded elements installed in the plates. Information boards are located at each end of the bridge. It seems to me that this bridge will not only be convenient for movement on it, but will also have a modern attractive appearance.
