The Berkshire Regional Transit Authority posted a notice on its website saying that, Tuesday morning, a deal between union members and the Authority was approved before a federal mediator.
That means all BRTA bus lines will be back to normal beginning on Wednesday.
The buses in Pittsfield were empty the week of December 5, as those who were usually behind the wheel were forming a picket line.
The group of operators picketed since Monday that week, which left the BRTA no choice but to suspend some of its services. The strike was due to an ongoing contract dispute that lasted almost half a year.
