Monica Tibbits-Nutt is parting ways with the Massachusetts Department of Transportation, where she has served as the secretary and chief executive officer, officials said Thursday.

Gov. Maura Healey said Tibbits-Nutt made the decision to step down from her positions as secretary of the Department of Transportation and CEO of MassDOT.

Tibbits-Nutt, who plans to return to the private sector, has agreed to continue as an advisor through Dec. 31 to ensure a smooth and efficient transition for MassDOT, officials said.

Tibbits-Nutt was named the secretary of transportation by Gov. Maura Healey in November 2023.

In her role, she was responsible for the four divisions of MassDOT: Highway, Rail and Transit, Registry of Motor Vehicles and Aeronautics. As secretary, she also served on the Massport and MBTA Board of Directors.

“Under her leadership, we made significant progress on some of the most complex and consequential infrastructure investments in state history, including the Cape Cod Bridges, West/East Rail, and the Sumner Tunnel Restoration.
