Imagine driving on a highway without any road signs. Without continually looking at a road map you would have no idea where you were or how to get where you wanted to be. Signs, of course, do not just magically appear on highways. MoDOT is responsible for making and installing the signs you see on state highways.

Here are five things you can tell your family, friends and neighbors about MoDOT’s Sign Shop:

• MoDOT produces about 130,000 signs per year.
• The largest sign produced was 36 feet wide by 16 feet tall.
• MoDOT saves more than $1 million annually by recycling signs.
• Sign life expectancy is 10 to 12 years.
• 3M, the company that MoDOT contracts with for sheeting, claims MoDOT is the largest user of electrocut film in the world.
