The Missouri Department of Transportation is urging driver to take it slow and be careful if they must travel this Christmas night.
In a blog post on the busiest travel day of the year last year, St. Louis mayor Francis Slay made it clear he wanted to make Lambert Airport smoke-free.
That goal is now policy.
The mayor's office announced Monday that starting January 2, passengers at Lambert who want to smoke will have to step outside. The airport's smoking lounges will no longer be available.
