The department took part in a multi-state earthquake drill.
MODOT simulated its emergency response plan.
The department's top priority after an earthquake would be to get highways open for emergency response, and then restore traffic as soon as it's safe.
Experts anticipate most of the respond would be needed in eastern Missouri, which would likely suffer the most damage.
With a plan in place, MODOT can get things moving again if disaster does strike.
"What it does, is we can react pretty quick to the roads system to make sure we can keep them safely on the highway," said Don Wichern of MODOT. "There'll be some drivers out there that will keep driving, that won't have a clue."
This is the first earthquake drill the Northwest Missouri Office of MODOT has had since it expanded from 12 counties to 20 two years ago.
