(Richmond, IN)--It’s bound to have a big impact on eastside Richmond businesses.  INDOT announced Monday that drivers going east or west on I-70 will not be able to exit at U.S. 40 for around two months.  The closure will begin in about two weeks.  During that time, crews will be removing existing pavement and begin roundabout construction at the interchange.  The fully reconstructed interchange isn’t expected to open for two and a half years, although the exits will again be usable by mid-September.  Also Monday, the Cardinal Greenway Trail closed in the area where it passes under I-70.  That closure will remain in place through at least the end of this year.
