Do all the above in one initial phase and wait and see the results. Then consider additional
additions to I-10 only if needed.
The financing method of the I-10 Interstate upgrades is questionable with GARVEE bonds so I recommend to use other financing methods (not a new tax).
Multiple alternatives, similar to the ones suggested, were considered in the Stage 0 Feasibility Study and did not move into the Stage 1 study due to a large number of environmental impacts.
