For the Thanksgiving holiday weekend, thousands of cars will be on the road as people throughout the US travel to be with friends and family. About 91% of Thanksgiving trips are made by car. What does that mean for carriers? Hours added to travel time.

Last year, congestion on the nation’s highways added over $9.2 billion in operation costs to the trucking industry. California led the nation with over $1.7 billion in costs.

The Weather Channel’s list of America’s top 10 most congested roads stem from these cities:

  1. I-95 Corridor (I-95 from NYC to Washington DC) – Some experts estimate that this 225-mile trek is the slowest stretch of highway nationwide during the holiday season.
  2. Boston (Westbound Massachusetts Turnpike from downtown Boston to I-84 in Sturbridge)
  3. Chicago (Borman Expressway I-80/I-94, the Tri-State Tollway)
  4. NYC (Throgs Neck Bridge and Whitestone Bridge)
  5. San Francisco (Eastbound I-80 to Sacramento and Tahoe)
  6. Atlanta (I-285 in both directions between I-75 and I-85)
  7. Washington DC (I-495 from Merrifield VA to Landover MD)
  8. Dallas (I-35)
  9. Detroit (Northbound US-23 and Northbound I-75 merge)
  10. Miami (The Palmetto Expressway near MIA)
