An 18-month construction project to extend the main Runway 14/32 at Lone Star Executive Airport in Conroe, Texas, has been completed. The addition of 1,500 feet of pavement, extending the runway at the dedicated business aviation airport to 7,500 feet, makes it possible for most business aircraft to take off without weight restrictions during the scorching Texas summer heat. The Houston-area airport is also anticipating the addition of U.S. Customs and Immigration service next April.
