Houston Transportation Pipe Dream: Convert every freeway within the loop into an underground subway line.

Houston is in dire need of transportation change as it grows.

1. Demolish freeways within the loop
2. Utilize cap and cover construction method (cheaper than tunneling) on existing freeway routes for a new subway, which would be more cost efficient.
3. Have the resulting space turned into a park.
4. No freeways within the 610
