Two more high-ranking officials have resigned from the state Department of Transportation. DOT Commissioner Vance Smith said in a statement that he accepted the resignations of Intermodal Director Erik Steavens, in charge of mass transit, and Human Resources Administrator Robin Stevens.

Asked if he had resigned voluntarily, Steavens declined to comment. No permanent replacements have been hired.

The DOT is also without a permanent treasurer or deputy commissioner, two of its top three positions.
