Hubert H. Humphrey Terminal

  • Location: St. Paul, MN
  • Architect: Miller Dunwiddie
  • Client: Metropolitan Airports Commission

Project Highlights

  • Cast-in-place concrete
  • Cantilevers and long spans


The two-story terminal building includes 12 gates, ticketing, and baggage claim and is primarily framed using cast-in-place concrete. The floor and roof decks were built using a wide-module pan and joist system. Although most of the structure was designed utilizing mild steel reinforcing, there are a number of cantilevered floor beams and long-span roof beams in the ticketing lobby area that were reinforced with post-tensioning tendons. The high bay concourse roof framing and expansive mechanical penthouses are structural steel. A 16-gate expansion is currently under design.
