The airport has recently undergone renovations which include a new terminal building with room for expansion, which was completed in 2009 and designed by CSHQA and The Abell Architectural Group Inc. The new terminal has an observation deck on the second floor, a restaurant for screened and unscreened passengers, and second-story loading bridges. Now that the terminal is complete, there is a main concourse, and two open air concourses. A new control tower was completed in late 2008; the $3.6 million, tower uses a state-of-the-art geothermal system to heat and cool the building.
