In a series of 16 videotaped interviews, leaders of top state transportation departments share how consulting engineers help them meet the changing demands of the nation's aging transportation networks.

Organized by Terracon, an engineering consulting firm based in Olathe, Kan., the “Green Light Series” was filmed at the Design-Build in Transportation Conference in March. The series includes interviews with:

  • Susan Martinovich, PE, director of the Nevada DOT and 2011 American Association of State Highway and Transportation Officials (AASHTO) President
  • Dave Nichols, chief engineer with Missouri DOT
  • Jeff Burst, Project Management Division administrator of the Louisiana DOT

With the underlying theme being innovation in transportation, the interviews address construction and engineering of highways, bridges, airports, and rail projects; and issues specific to the industry, such as how their clients' needs are changing the way design-build teams do business.
