complete rebuild of the southwest quadrant from SR-201 to 4700 South in Taylorsville was completed. The $105 million project replaced the concrete road surface, added auxiliary lanes between exits, resurfaced and widened several bridge decks, and replaced two major bridges over SR-201. As part of the original proposal of a belt route through Salt Lake City, the southeastern quadrant received the designation of I-415. To maintain continuity in the belt route, the 415 number was replaced in favor of the I-215 designation covering the entire route in 1969.
