Boston 2024, the group pushing to make Boston the host city for the 2024 summer Olympics, has hired the state's former transportation secretary as its new CEO.


Richard Davey, the transportation boss under former Gov. Deval Patrick, succeeds Dan O'Connell, who was housing and economic development secretary under Patrick.


John Fish, president of Suffolk Construction, is chairman of Boston 2024, which is also being assisted by executive vice president Erin Murphy Rafferty, a former Greater Boston Chamber of Commerce official, and Northwind Strategies, a consulting firm that features numerous former Patrick administration aides.


In a statement, Fish called Davey the "perfect fit" to continue O'Connell's work.


Boston 2024 is counting on public infrastructure investments and the public transportation system to effectuate its vision of a "walkable" Olympics.


Davey worked previously as general manager of the MBTA and at the Massachusetts Bay Commuter Railroad Company, the former operator of the state's commuter rail system.
