TERRE HAUTE, Ind. (AP) _ Indiana State University officials hope to begin a $4 million project to demolish two towers built in 1968 by the end of the year.
 
  The Tribune-Star reports the project to raze the 15-story Statesman Towers will require state approval because of its cost. ISU Vice President for Business Affairs Diann McKee says she doesn’t expect it to go out to bid until this fall.
 
  The buildings have been used as residence halls and academic buildings, but ISU officials say they are expensive to maintain and aren’t energy efficient.
 
  The method of demolition hasn’t been determined.
 
  ISU director of capital planning and improvements Bryan Duncan says the work could take four to six months once it begins.
