1) One idea looks at creating a series of essentially non-negotiable frameworks that the design would have to ensure. These include no new right-of-way taken, a reduced footprint anywhere possible (especially on on-off ramps) to gain developable (taxable) land, and the construction of increased connectivity across the freeway through more bridges. The more negotiable but ideal solutions would include: a trenched design that allows for the entire city grid to extend across the top of the freeway, a deck park (similar to Klyde Warren Park in Dallas) on top of the freeway between 6th and 9th Streets, and a design to enable streetcar use/ expansion across freeway.
