Lambert Concourse reopens today

City officials are celebrating the reopening of the C Concourse at Lambert St. Louis International Airport today.

The concourse has been closed since April 22 of last year when a tornado hit causing significant damage.

The concourse is new and improved according to director Rhonda Hamm-Niebruegge with brighter ceilings, new lighting and new restrooms among the improvements. Hamm-Niebruegge recalls the evening the tornado hit.
