Create a detailed architectural visualization of a circular ramp with a canopy roof. The ramp connects a modern bridge over a serene river to a pedestrian pathway that runs alongside the riverbank. The bridge features sleek, contemporary design elements with minimalist railings. The circular ramp should gracefully spiral down from the bridge, integrating seamlessly into the natural landscape. The canopy roof should provide shelter and be designed with a light, airy structure, possibly using transparent or semi-transparent materials to blend with the surroundings. The pedestrian pathway beside the river should be inviting and well-lit, with greenery and benches lining the path, enhancing the overall aesthetic and user experience. Include people walking and biking to show the ramp in use.
