Driving up I-35 this morning and looking at the I-35/I-30 mixmaster, which has ramps to the Express Lanes. Hard to believe the toll authority, the state, the feds, the railroad, will be able get behind this plan. I suppose there is some level of synergy potentially with the I-30 Corridor Project, but I don't think they're going to want to add cost to that. It would have to be in line for after that is complete which will likely take a decade or more to complete. Interesting study but I'm not sure it could ever get traction.
It's just a thought.
Besides, the ramps on that mixmaster would stay. The only thing that's changing is that section of 35W.
