St. Louis’s Lambert International Airport traces its history back to aviation’s beginnings. The man it’s named after–Albert Bond Lambert–learned to fly with the Wright brothers. In 1928, the facility became one of the first municipally owned airports in the U.S. In a bid to give the facility a refresh, the city has been pursuing a plan to hand day-to-day operations to a private company. It’s one of dozens of public-private partnerships—including a $9 billion plan to expand highways outside Washington or the build-out of a “smart city” system in Kansas City, Mo.—that have been pitched throughout the U.S. in recent years to provide much-needed upgrades to infrastructure.
