A rooftop view of Lambert’s reconstruction project on Runway 12R-30L.

A rooftop view gives the best perspective to a massive project underway to reconstruct a major portion of Runway 12R-30L. For weeks now, contractors have been chipping away at the decades old runway in preparation for a new concrete base that needs to handle hundreds of aircraft landings and takeoffs each day. In the forefront, is a massive hill built from the remnants of the former runway. The old concrete is crushed for reuse as a base for the new runway. The project will be completed by late fall.
