A Frontier Airlines jet taxis behind the dusty work of a concrete breaker vehicle which is being used in rebuilding a section of Runway 12R-30L at Lambert-St. Louis International Airport.

Rebuilding or rehabilitating taxiways and runways are a key part of maintaining a safe airfield. This summer, the major project is the replacement of approximately 3,800 ft of Runway 12R-30L, one of Lambert’s two parallel runways. Concrete breaker vehicles do most of the dirty work. The remote controlled vehicles use a guillotine-style drop hammer to crack the worn out pavement so crews can remove the concrete debris and recycle for other uses.
