Traffic congestion at the intersection of Interstates 285 and 85 North, Atlanta’s so-called “Spaghetti Junction,” and other bottlenecks on the U.S. National Highway System (NHS) added over $63.4 billion in operational costs to the trucking industry in 2015, the American Transportation Research Institute (ATRI) reported.

ATRI, part of the American Trucking Associations, updated its annual “Cost of Congestion to the Trucking Industry” research, and its Top 100 Truck Bottlenecks List, which named the Atlanta intersection as the nation’s worst for the second consecutive year. Most of the backups occur in big cities.

Here’s the rest of the Top 10:

2) I-95 at State Route 4 in Fort Lee, New Jersey
3) I-290 at I-90/94 in Chicago
4) I-65 at I-64/71 in Louisville, Kentucky
5) I-71 at I-75 in Cincinnati
6) SR 60 at SR 57 in Los Angeles
7) SR 18 at SR 167 in Auburn, Washington
8) I-45 at US 59 in Houston
9) I-75 at I-285 North in Atlanta
10) I-5 at I-90 in Seattle

The congestion analysis found the top 10 states experienced costs of over $2 billion each, with Florida and Texas leading with over $5 billion each. ATRI calculated delays on the NHS totaled more than 996 million hours of lost productivity, or 362,243 commercial truck drivers sitting idle for a working year.
