Thursday marked a big milestone for construction of a new passenger terminal for the Brownsville South Padre Island International Airport, which celebrated installation of the final steel beam in a traditional “topping out” ceremony.

The $43.8 million, 91,000-square-foot terminal project broke ground in late 2016 and is scheduled for completion in the fourth quarter of 2020. Construction remains on schedule and within budget, according to Airport Director Bryant Walker, who noted that roughly 95,000 man-hours have gone into the project so far.
