We use the systems that Massachusetts Secretary of Transportation Richard Davey has power over daily: the MBTA, turnpikes, highways, tolls, bridges, the port authority, and more.

Davey joined Boston Public Radio's Callie Crossley in studio to field questions and calls from listeners. Among the things he spoke about: tolls, traffic, MBTA debt and fare hikes, how the MBTA is serving communities of color, and more.
