Construction Division Director
Duane Milligan, P.E., is the director of Construction.
Milligan began his career with TxDOT in 2003 as an engineering assistant in Bridge Design. 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.
He then 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.
Milligan then became the project manager of the Dallas Horseshoe Project, the first Design-Build project to be undertaken by TxDOT under the Design-Build authority granted by the Texas Legislature in 2011. As project manager, he oversaw the procurement, design, and construction of the $798 million project that rebuilt portions of l-35E and I-30 near downtown Dallas, two of the most congested freeway sections in the nation.
In August 2014, Milligan was named director of construction for TxDOT’s Dallas district and served in that capacity until April 2019 when he became deputy director of the Construction Division. He won the Luther DeBerry Award for his contributions to the state of Texas in 2018.
Milligan earned his bachelor's degree in civil engineering from the University of Texas at Austin in 2000 and then earned his master's degree in civil engineering from the University of Houston.
