A regional board Thursday will recommend nine metro Atlanta transit projects for possible state funding next year. At a time of tight budgets, there’s no guarantee that funding will come. But the project list could set the stage for perennial state funding at a time when metro Atlanta is poised for a transit construction boom. Last month the board discussed narrowing the list to three or four projects, but opted to pass along nine projects for consideration. Among them are several bus rapid transit lines, the rehabilitation of MARTA stations and construction of new park-and-ride lots.
