The Liberty Municipal Airport started out rather humbly as a grass landing strip in the 1950s and later became a paved runway in the early 1960s. Hangars were initially erected at five different areas on the airport grounds. Two of these were removed due to declining conditions, and two others were destroyed in September 2008 during Hurricane Ike. One is still in use today.
During the 1980s, two orange community hangars were built and are in use today. In 1980, the runway was lengthened to 3,801 feet. The runway had a slurry seal put on it in 1994 and was remarked at the same time. The runway lights and concrete ditch drainage were added in 2009.
In 2012, thanks to the hard work of the Liberty City Council, Liberty Community Development Corporation and funding from the FAA and the State of Texas, the airport completed major upgrades which included security fencing, twenty new t-hangars, a pilot's lounge, and a resurfaced apron. In addition, a refurbished fuel farm consisting of two 12,000 gallon tanks for 100LL Avgas and Jet A fuel was put into service.
