A disaster exercise is coming up this summer, and the City of Grafton will play a role. 

The Missouri National Guard Mobile River Bridge Company will be in the river town just north of St. Louis between July 15 -17 as part of a mock New Madrid Fault earthquake response exercise. Grafton Mayor Mike Morrow explains the scenario.

He says the company will use float bridge, ribbon bridge trucks, and Chinook helicopters as part of the exercise. The ferry landings on both sides of the river will be used, and Morrow says this will be a fairly big exercise over the three days.
