using my existing plan as the base enhance the area while strictly preserving the original layout scale road geometry and building positions maintain the same camera angle and perspective replace all existing pedestrian crossings white crosswalk lines with elevated pedestrian bridges crossing above the roadway these overpasses should allow pedestrians to move safely without interrupting vehicle traffic design the pedestrian bridges with a clean and contemporary architectural style ensuring they integrate harmoniously into the campus environment include access ramps or stairs and use materials such as wood steel or concrete to create a high quality and realistic appearance ensure the roads remain uninterrupted with no at grade pedestrian crossings maintain clear separation between pedestrian and vehicle circulation keep the rendering professional and clean with minimal or no people and no vehicles if not required focusing on design clarity and spatial organization
