Leaders in Georgia celebrated the addition of 400 new jobs in Trenton.
Officials held a groundbreaking ceremony Thursday for Vanguard's National Trailer Plant. 
The semi-trailer manufacturing plant will be 350-thousand-square-feet and cost about 30 million dollars to build.
Governor Nathan Deal said this will give people a reason to stay in the community. 
Vanguard will eventually make about 10-thousand semi-trailers at the plant each year.
