After considering three potential designs, it was decided that a pedestrian bridge to replace the existing bridge would be best for the community. The proposed design and redevelopment of the surrounding areas is shown in Figure 1 below. Figure 2 and Figure 3 show the alternative proposed designs that were considered. A weighted decision matrix was used to assist in the selection of the best design which can be seen in Table 1. Due to the advanced deterioration of the existing bridge, the longevity of the proposed bridge received the highest weight.
Criteria | Vehicular Bridge on a New Alignment | Vehicular Bridge Spanning from Rumson Road | Pedestrian Bridge Spanning from Rumson Road |
Cost (1) | 1 | 2 | 3 |
Longevity (2) | 1 | 2 | 3 |
Design Constraints (1.5) | 2 | 1 | 3 |
Realistic Constraints (1.5) | 3 | 2 | 1 |
Community Impact (1) | 3 | 2 | 1 |
Total Score | 13.5 | 12.5 | 16 |
