Oh great, so the solution to eliminating a security risk is to consolidate passengers into an even more confined space with curbside access! That's convenient for the every day terrorist who wishes to drive past curbside and shoot directly into the complex. Why not look at alternatives to make the 5th floor check points more secure? Ballistic glass could be installed or areas can be blocked off. Consolidating everything onto one floor does not seem to be a feasible solution and sounds like it would limit airline growth. Dumb project. Airports are meant to be a mechanism for travel, not to be a shopping mall. Passengers want to get to their gates first and foremost. Also, let's face it. This is DENVER. So unless they're planning on selling endless amounts of Northface, granola or marijuana (whoops, forgot the whole cannot ship across state lines thingy), this will not be successful. Invest in concourse concessions instead since the majority of current concourse concessions blow.
