WEST LAFAYETTE, Ind. (AP) _ West Lafayette officials are worried about big additional expenses coming soon when the city has to take over several streets around the Purdue University campus from the state.
 
  That handover is expected this fall under a 1997 agreement when the Indiana Department of Transportation opens up the new U.S. 231 bypass around West Lafayette.
 
  The city will then be responsible for maintenance and snow removal on the streets that now carry five state highway routes through and around Purdue.
 
  Mayor John Dennis tells the Journal & Courier that he hopes state officials will help with the city’s added costs.
 
  Highway department official Alan Plunkett says he’s been talking with the mayor but the agreement in place has the city taking over those streets once the bypass is done.
