According to the Denver Post, the first signs of formal construction on Denver International Airport's $500 million South Terminal project will appear Wednesday when traffic controls are installed on some of the facility's roadways. Work already is under way on the East Corridor Light Rail Line that will run from Union Station in downtown Denver to DIA; trains are expected to begin running in 2016. The South Terminal Redevelopment project also includes a 500-room Westin hotel connected to the terminal. A train station designed by Spanish architect Santiago Calatrava was planned, but the architect pulled out of the project last month. Airport officials have told the Post that they expect to be able to use Calatrava's concepts.
