This should come as no surprise to most people who have driven on Chicago’s so-called “expressways:”

A new analysis of 30 freight bottlenecks assesses the severity of 30 freight bottlenecks within the U.S. interstate system, using unique analysis methods and data to produce a severity ranking for each location.
This research by the American Transportation Research Institute dovetails with the ongoing Freight Performance Measures initiative sponsored by the Federal Highway Administration and managed by ATRI.
The ATRI analysis of 30 national bottlenecks prioritizes chokepoints on the highway system previously identified by the research community. ATRI researchers used GIS/GPS technology and truck-specific information, as well as sophisticated analysis techniques, to determine what time of day freight was affected by traffic congestion and where the results of such congestion were the most severe.
According to the ATRI analysis, using a “total freight congestion value,” the biggest bottleneck on the list is the I-80 @ I-94 split in Chicago, which was fifth on the original list. The second worst was the I-95 @ SR-4 intersection in Bergen, N.J. Third was the I-90 @ I-94 Interchange (Edens Interchange), Chicago.
One of the reasons for the I-90/I-94 bottleneck being so bad is that there is no way for trucks to go from eastbound 94 to westbound 90, or vice-versa.
