TUCSON, AZ - Tucson International Airport has broken ground on a new control tower.
The Arizona Daily Star reports officials marked the site Wednesday where a new tower will be built.
They say at 252 feet, the tower will be twice the height of the existing 55-year-old tower.
Tucson Airport Authority CEO Bonnie Allin says the old building will be preserved.
The new tower is expected to have a 13,000-square-foot base and an adjacent solar panel farm that will contribute some electricity.
The Federal Aviation Administration is investing $42 million in the project.
Tucson airport officials plan to commercially develop thousands of acres of airport-owned land in order to increase cross-border freight transactions.
