Geometric Bridge First Attempt

So I have mocked up this rough model trying to incorporate a geometric element into the design. It hasn't turned out very well due to trying to combine the curvature form it must follow, with geometric elements. But any who, below are some images of how it came out:

I have then just chucked some wood textures on it to try and give it somewhat of realism. The geometric triangles would have glass or something similar to James' pattern for his tree houses. This would be for safety purposes as well as aesthetic purposes.
