figures, seemingly incongruous especially after the issues caused by the 2021 I-40 bridge closure which forced all traffic crossing the river at Memphis (including trucks) to use this bridge, may be explainable by way of the routing of I-40, I-55 and U.S. 78 (supplanted in part by I-22 and its connecting freeway I-269) thru the Memphis area, as well as the locations of major distribution and transportation hubs in the area ranging from the FedEx Express "super hub" at Memphis International Airport to regional grocery warehouses operated by Kroger and Associated Wholesale Grocers . Despite the U.S. Supreme Court's landmark 1971 decision in Citizens to Preserve Overton Park v. Volpe that led to the cancellation of I-40's originally planned route thru Overton Park (which in part dictated the location of the I-40 bridge), the advantages of I-40 as a cross-country interstate proved to be undeniable; thus the I-40 bridge is used by long-haul truckers & other cross-country travelers, as well as by commuters from Arkansas going to & from jobs in downtown Memphis which is generally closer to that bridge. Meanwhile, most Memphis area distribution and transportation hubs are in the southern part of Memphis and its Mississippi suburbs such as Southaven and Olive Branch, with ready access to I-55 via such routes as I-240 across south Memphis (not to be confused with the I-240 in north Memphis that became I-40 after the Overton Park cancellation), U.S. 78, I-22 and I-269; thru truck traffic to & from Birmingham, Alabama and points east (such as Atlanta) also flows thru Mississippi & south Memphis via U.S. 78, I-22, I-269 and I-55. Finally, though both I-40 and I-55 go thru Memphis, they actually cross in West Memphis, Arkansas and not Memphis proper; the rerouting of I-40, along with both the original and current designs of its interchange with I-240 west of Overton Park, do not facilitate high volumes of trucks from the south seeking to use the I-40 bridge. Thus, it is generally easier for trucks going between Memphis (as well as Birmingham via U.S. 78 / I-22) and points west of Memphis, ranging from Arkansas grocery stores all the way to Los Angeles, to use this bridge to reach I-40 at West Memphis rather than the I-40 bridge itself, on top of the expected traffic using I-55 (and in some cases I-57 further north) to reach St. Louis, Chicago and other major
