Construction will begin this month on a $47 million addition to Harrah's East Chicago riverboat casino. Las Vegas-based Harrah's Entertainment Inc. expects work to be completed in fall 2001 on the 15-story, 292-room tower.

Each guestroom will be at least 504 sq. ft., 70% larger than the Chicago region's standard hotel room, according to Harrah's. The company also recently completed renovations at Harrah's Joliet in metro Chicago.
