Milligan began his career with TxDOT in 2003 as an engineering assistant in the district's bridge design section.
From there, he moved to the Southwest Dallas County Area Office working first in design, then in construction. His construction experience included managing the $216 million SH 161 Western Extension Project.
Following this assignment, he moved to the district's East Dallas Area Office where he managed multiple construction projects, including the Woodall Rodgers Deck Park Project (Klyde Warren Park) and the Woodall Rodgers Extension Project, which incorporated the construction of the Margaret Hunt Hill Signature Bridge designed by Santiago Calatrava.
