ST. LOUIS (AP) — More than 18 months after a tornado ripped through Lambert Airport in St. Louis, work is about to begin to make over two entrances damaged by the twister.

Lambert officials say they’re beginning to redo the entrances for Terminal 1. They say the terminal’s lower level entrances will be designed to enhance the airport’s historic architecture.

Glass panels will allow natural light that will brighten the pathway in the area of the lower level baggage claim. The entrance reconstruction is part of a $22 million tornado restoration campaign.

The tornado on April 22, 2011, blew out hundreds of panes of glass and damaged much of the airport, but no one was killed.

The project is expected to finish by the spring of 2013.
