Oklahoma Transportation

Oklahoma is an integral point on the U.S. Interstate Network. Three major interstates connect at a point in Oklahoma City known as "The Crossroads of America." These interstates are: Interstate 35, Interstate 40, and Interstate 44.

Interstate 35 traverses the state from north to south across the center of the state. Interstate 40 runs through the center of Oklahoma in a bisecting fashion, traversing in an east/west direction. Interstate 44 runs through Tulsa, bisecting the state from the northeast to the southwest. Interstate 44 is a turnpike for most of its duration through the state, with exceptions within the cities of Tulsa, Oklahoma City, and Lawton. In addition, the state has 10 major turnpikes. Oklahoma also has the longest drivable stretch of Route 66 in the country.

The state is connected to the nation's rail network via the Heartland Flyer, an Amtrak-operated rail line which stretches from Oklahoma City to Fort Worth, Texas. There are also plans to connect the Heartland Flyer to Tulsa. Two major airports serve Oklahoma: Will Rogers World Airport in Oklahoma City and Tulsa International Airport. There are also numerous other regional and general aviation airports. See List of airports in Oklahoma for further information. In addition, the Tulsa Port of Catoosa, the nation's most inland seaport, is the state's primary connection to international ocean trade routes.
