Transportation
Houston’s freeway system is made up of 575.5 miles of freeways and expressways in a 10-county metro area. Its highway system uses a hub-and-spoke freeway structure serviced by multiple loops. The innermost loop is Interstate 610, which encircles downtown, the medical center, and many core neighborhoods with around a 10-mile diameter. Beltway 8 and its freeway core, the Sam Houston Tollway, form the middle loop at a diameter of roughly 25 miles. A proposed highway project, State Highway 99 (The Grand Parkway), would form a third loop outside of Houston. Currently, the completed portion of State Highway 99 runs from just north of Interstate 10, west of Houston, to U.S. Highway 59 in Sugar Land, southwest of Houston, and was completed in 1994.
Houston also lies along the route of the proposed Interstate 69 NAFTA superhighway that will link Canada, the U.S. industrial Midwest, Texas, and Mexico. Other spoke freeways either planned or under construction include the Fort Bend Parkway, Hardy Toll Road, Crosby Freeway, and the future Alvin Freeway.
The Metropolitan Transit Authority of Harris County, Texas, or METRO, provides public transportation in the form of buses, light rail, and lift vans. METRO's various forms of public transportation still do not connect many of the suburbs to the greater city, causing Houstonians to rely on the automobile as a primary source of transportation.
METRO began light rail service (METRORail) on January 1, 2004. The inaugural track runs about 8 miles (13 km) from northern Downtown at UH–Downtown to the Texas Medical Center and Reliant Park. METRO is currently in the design phase of a 10-year expansion plan that will add five more lines to the existing system.
Amtrak, the national rail passenger system, provides service to Houston via the Sunset Limited (Los Angeles–New Orleans), which stops at a train station on the north side of the downtown area. The station saw 10,855 boardings and alightings in fiscal year 2006.
Houston is served by two commercial airports. The largest is George Bush Intercontinental Airport (IAH), the ninth-busiest in the United States for total passengers, and seventeenth-busiest worldwide. Bush Intercontinental currently ranks third in the United States for non-stop domestic and international service with 182 destinations. In 2006, the United States Department of Transportation named George Bush Intercontinental Airport the fastest-growing of the top ten airports in the United States. Houston is the headquarters of Continental Airlines and Bush Intercontinental is Continental Airlines' largest hub. The airline offers more than 700 daily departures from Houston. In early 2007, Bush Intercontinental Airport was named a model "port of entry" for international travelers by U.S. Customs and Border Protection.
The second-largest commercial airport in Houston is William P. Hobby Airport (named Houston International Airport until 1967). The airport operates primarily small to medium-haul flights and is the only airport in Houston served by Southwest Airlines and JetBlue Airways. Houston's aviation history is showcased in the 1940 Air Terminal Museum located in the old terminal building on the west side of Hobby Airport.
The third-largest airport is Ellington Field, a former U.S. Air Force base, used by military, commercial, government and general aviation sectors.
The Federal Aviation Administration and the state of Texas selected the "Houston Airport System as Airport of the Year" for 2005, largely because of its multi-year, $3.1 billion airport improvement program for both major airports in Houston.
