Great Dane in Terre Haute recently built its 100,000th trailer.
It was built especially for the decades-old customer The Celdadon Group.
The facility's been open for 17 years and employs more than 450 people.
Officials say the milestone trailer shows is a sense of accomplishment both now and in the future.
"The next few years are going to be a very exciting time for Great Dane. We've got a lot og changed on the horizon, a lot of updates to our models of trailers, a lot of changes that we're going to push through for our customers. So the next few years are going to be a jumping board for where we go in the future," said Cory Lookebill, plant manager at Great Dane Terre Haute.
Great Dane's Terre Haute facility manufactures around 8,000 trailers a year.
The company's other location in Brazil, Indiana has three production lines and is currently hiring.
