What's wrong with the Taconic State Parkway?
Thus, the Taconic corridor is beautiful and inhabited by many tree hugging NYC
weekenders. I would leave it alone.
Conversely, no apparent reason why NY 22 corridor should NOT have an
interstate. This is a more depressed area that could use some development, ROW
cheaper, etc.
