An expansion program was carried out between 2011 and 2013, which extended the runway from 4,750 feet (1,450 m) to 6,234 feet (1900 m). The runway was resurfaced and lighting systems were upgraded. The terminal building was also renovated, including improvements to security screening, passenger facilities, and parking infrastructure. The extension increased the airport's operational capacity, allowing it to accommodate larger regional aircraft.
