The last man standing

Jeffrey Mullan is out walking his dog in the fading summer twilight. I see him as I drive down a street in Milton and pull over to say hi. It’s the second time in weeks that I’ve bumped into him (the first was at a road race in Milton where he was handing out a prize), and the conversation turns quickly again to his job as executive director of the Massachusetts Turnpike Authority. He says he’s trying to bring all of the state’s roads and bridges under unified management. Cars squeeze by behind him as we chat, but he pays them no heed. “This is big,” he says. “You ought to think about writing something about it.”
