7.4. To increase the amount of usable land because the space beneath the bridge can still be used
7.5. To use for public transportation such as trains while not affecting existing roads

8.2. Stone in the early time
8.3. Steel
8.4. wood
8.5. Reinforced and prestressed concrete
8.6. Cement
9. (Jeff/Bridge Selected: 七賢橋) Why would we need to build a bridge on the Love River?
9.1. The bridge finished its construction in November, 1977, and is already in need of repair.
9.2. It is one of the huge bridges across Love River, that had a lot of traffic.
9.3. Because it is a beam bridge with little to no design elements, and it is not aesthetically pleasing. It does not fit in to the artistic philosophy what Kaohsiung wants to represent now.
9.3.1. As what represents in the Art Museum of Gu- Shang District.
