If you're flying into northern Alabama, you might very well be landing at a facility operated by the Huntsville-Madison County Airport Authority. The agency operates the Huntsville International Airport, which handles about 100 flights daily. In addition, the Huntsville-Madison County Airport Authority oversees the International Intermodal Center, a US Customs Port of Entry which is equipped to handle cargo arriving by airplane, train, or truck. The agency also maintains the 4,000-acre Jetplex Industrial Park, which offers air, rail, and truck transportation.
