Karina Ricks and Leah Treat, two top deputies at DDOT, will be leaving the organization they've worked at for a combined 22 years.
Ricks says the department's career employees are in a sort of purgatory, because Gray still hasn't chosen a permanent director, five months into his term.
Council member Tommy Wells, who chairs the transportation committee, says the city will miss Ricks and Treat, but their departures aren't a sign that DDOT is undergoing a mass exodus.
"I have a lot of confidence in the department," he says. "The department's not gutted. We still have a lot of good folks there."
A spokesperson in the mayor's office says this kind of staff turnover is normal when a new administration comes in.
