Major projects Between May 1980 and March 1982, a major project was conducted on I-40 in Knoxville that widened the route, eliminated several interchanges, added frontage roads, and reconstructed the congestion-prone cloverleaf interchange with I-75, which had earned the nickname "Malfunction Junction", into a three-level stack interchange. This was conducted as part of a larger $250 million (equivalent to $ in ) road improvement project in the Knoxville area in preparation for the 1982 World's Fair.
