When McCarran International Airport's $2.4-billion third terminal complex opens on June 27, it will mark the beginning of long delays for new big projects in the region.

The three-level, 1.9-million-sq-ft building comes with a 5,954-space, 2.3-million-sq-ft, $121.7-million garage built by McCarthy Building Cos., an eight-mile elevated roadway system and a 900-ft-long automated connecting tram. It brings the four-runway, 2,800-acre McCarran to final build-out.
