Design drawing of a high-level corridor

Quick answer：

The design drawing of a high-level corridor typically includes detailed plans for the construction of elevated walkways or passages that connect buildings or other structures at a higher level. These corridors are often used in large complexes or urban environments to provide convenient access between different floors without the need to use stairs or elevators. The design would incorporate architectural elements such as structural supports, lighting, ventilation, and possibly escalators or elevators. It would also address safety and accessibility requirements, as well as integration with the surrounding environment.
