This summer, NHPR has brough you stories from along Route 4 in New Hampshire. 

The roadway stretches across the state, covering many regions from the Seacoast to the Vermont border. That's a lot of road to manage.

Bill Lambert is a statewide administrator and traffic engineer for the New Hampshire Department of Transportation. He sat down with NHPR's Morning Edition Host Rick Ganley to answer some listener questions about traffic and road safety along Route 4.
