Interstate 55 runs 964 miles from LaPlace, Louisiana (just outside New Orleans) to Chicago, Illinois, shadowing the Mississippi River for much of its length. It is the principal north-south corridor of the central US, tying together New Orleans, Jackson, Memphis, St. Louis, and Chicago. The route replaces much of historic US Route 66 between St. Louis and Chicago.
For freight, I-55 is the main truck route along the Mississippi River intermodal network. Container traffic from the Port of New Orleans and the Memphis FedEx hub moves on I-55, and the St. Louis-to-Chicago segment is a heavily used freight route, designated a Tier 1 nationally significant corridor by the Mid-America Freight Coalition for its truck volumes and its connections to other major interstate freight corridors. The route connects to I-40 at Memphis (one of the busiest east-west truck transfers in the country), to I-70 and I-64 at St. Louis, and to I-80 / I-90 / I-94 in Chicago.
Geographically I-55 is mostly flat, crossing the Mississippi delta in Louisiana, the bluffs around Memphis, the rolling Ozark foothills in southeastern Missouri, and the prairie of central Illinois. Weather hazards are dominated by hurricane evacuations from coastal Louisiana, Mississippi River flooding that closes the Bonnet Carré and other low-lying segments, severe weather across the Mid-South, and lake-effect snow at the Chicago terminus.

Memphis-Arkansas Bridge, TN/AR (MM 1 TN - 0 AR)
The I-55 Memphis-Arkansas Bridge is one of the few Mississippi River crossings between Memphis and Vicksburg. When the parallel I-40 Hernando de Soto Bridge was unexpectedly closed in 2021, all I-40 traffic was rerouted onto the I-55 bridge, overwhelming capacity for weeks. Plan for the worst whenever either bridge is restricted.
Bonnet Carré spillway, LA (MM 0-15)
I-55 in Louisiana crosses the Maurepas swamp and runs low to the Bonnet Carré spillway. Major Mississippi River flooding events have closed the corridor in the past. Hurricane storm surge can also flood the route. Monitor 511 Louisiana..
Chicago Stevenson Expressway (MM 281-295)
I-55 in Chicago (the Stevenson Expressway) ranks among the nation's worst truck bottlenecks: it was the #3 bottleneck in the country in ATRI's 2024 ranking, though its congestion has been easing since (#21 in 2025, #38 in 2026; ATRI Top 100 Truck Bottlenecks). Container drayage between the BNSF Logistics Park and the I-90 / I-94 stack moves on I-55. Plan deliveries outside the 6-9 AM and 3-7 PM peaks.
Mississippi Delta severe weather (MM 78 LA - 285 MS)
I-55 across Louisiana and Mississippi runs through Dixie Alley, where nighttime tornadoes and damaging-wind events are common March through May. Park under solid shelter when warnings are active.
St. Louis I-44 / I-55 / I-64 / I-70 stack (MM 207)
The I-55 stack in central St. Louis converges I-44, I-55, I-64, and I-70 in a tight downtown footprint. Lane drops, tight curves, and short merge zones cause chronic incidents. MoDOT publishes real-time alerts.
