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.

After nearly five years of construction, Terminal D is back.

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.

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