8/15/17- After reviewing the comments the design team WSP has narrowed down the options from eight to three and is investigating options on each.
1. Prefabricated Truss-with the possibility of making the truss deeper and replicating the curvature of the existing bridge
2. Perfabricated Steel Arch/Tunable System- With the possibility of improving the aesthetics of a couple of details noted in the comments.
3. Steel Tied Arch- possibly combining the preferred attributes of Alternatives 3 & 6, noting that extending the base o f the arch to a lower elevation as shown in Alternative 6 would not be preferred due to hydraulics, permitting and other concerns.
