The final shift at the Kellogg's plant in London will start work at 11 p.m. on Wednesday.
The shift will end Thursday morning, meaning the final box of cereal will roll off the line sometime between 7 a.m. and 9 a.m.
A skeleton crew will remain at the facility to help fully shut down the plant on Dec. 23.
The Kellogg's plant in London has been in operation since 1924 and its closure leaves hundreds out of work.
