Photo of the Week: Snow Prep Posted on August 14, 2020 in News Temps may be pushing into the 90s, but STL is already thinking about snow. It takes a lot of prep work to get more than 40 pieces of snow removal equipment ready to clear four runways that average 9,100 feet long and more than 150 feet wide. That is like driving a one lane road almost 335 miles from STL past Topeka, Kansas.
