West Pier, an expansion to Terminal D, will open Oct. 22 to the public. The expansion, which is part of the IAH Terminal Redevelopment Program, will have space for six wide-body or 10 narrow-body airplanes.

The long-awaited expansion of George Bush Intercontinental Airport Terminal D is complete and will open Oct. 22. Why it matters: The renovation and expansion of the international terminal will accommodate growing passenger and airline demand while strengthening Bush Airport's status as a global aviation hub.

After years in development and over a billion dollars in investment, the expansion of a terminal at George Bush Intercontinental Airport (IAH) is ready to open.

Closure of lanes will occur over night during the month of October to get rid of the old elevated departures ramp.
