Well, we’ve now entered a phase of the ARC drama where I think it’s fair to wonder whether Chris Christie may simply be adept at brinkmanship. After having a sit-down with Ray LaHood in Trenton today, Christie agreed to reconsider his decision to kill the trans-Hudson rail tunnel project. Sprawl vs. compact development, traffic vs. trains, economic stagnation vs. an engine for growth — it all hangs in the balance.

The parties have mapped out a two-week process for U.S. DOT and New Jersey officials to review different options to move the ARC project forward. The Star-Ledger has the story.

If you’re an optimist about these talks, I think the relevant question now is: What conditions will LaHood have to meet? Share your scenarios in the comments.
