Wednesday morning, the Gwinnett County Commission approved a contract with MARTA and called for a transit referendum next March.

Voters will decide whether or not to join MARTA under the new regional transit agency "The ATL" and pay a penny sales tax to fund the expansion.

Tyler Estep is the Atlanta Journal-Constitution's reporter covering Gwinnett County. He was at the meeting this morning and joined me via phone to talk about the vote.
