A proposal in 1991 would have moved the city 's main post office to a triangular lot along State Street , but this plan was never put in place and that site is now home to Dr. Martin Luther King , Jr . Plaza . The post office suffered an anthrax scare during the U.S. anthrax attacks of 2001 , when a postal worker discovered brown powder in a sorting bin . Another closing plan was announced in 2009 , where the building would be sold and its operations consolidated with the other three existing offices in Racine . Since then , the downtown office 's staff and open hours have both been reduced , but it remains open as of May 2017
