Malfunction Junction - Tennessee

Tennessee

• Interstates (40/275 (originally Interstate 75)) in Knoxville, which caused traffic snarls before diversion of I-75 west of Knoxville and reconfiguration of the interchange.Map and Aerial photo
• Interstates (240/55) in Memphis. Interstate 55 assumes the southbound (from Mississippi) and westbound (from the Mississippi River and Arkansas) routes of this interchange, while Interstate 240, formerly Interstate 255, consists of the northbound and eastbound. Due to the irregular exchange of route markers, expressway exits have been extensively modified to handle the excess amount of traffic (compared to driving from east-to-west or north-to-south). Accidents frequently occurred not only to the confusion caused by route changes, but by trucks unprepared for the low clearances used on the Arkansas-bound stretch of Interstate 55. (Although not part of the interchange, tractor trailers and tractor tankers would frequently get lodged under the low bridges found on I-55 west of this junction.) Map and Aerial photo
