Seattle/Tacoma – Coming in at number 10 on the list of worst-congested U.S. cities in 2010, Seattle/Tacoma is 15th in terms of population size at 3.4 million. Average trip time is 49 percent longer than normal. Worst day/time is Thursday at 5:15 p.m., making Sea/Tac the fourth top 10 city with Thursday as the most-congested travel day.
Of course, none of this makes us feel any better, whether we’re shuttling the kids to/from school or extracurricular activities, driving in or around town on business, shopping, running errands or just plain living. One thing is abundantly clear, however. If you’re in cities with the worst traffic congestion – and you know who you are – you know exactly when to avoid being on the road.
Or just prepare to spend a lot of wait time behind the wheel.
Final point worth mentioning – the five least-congested metro areas are: Palm Bay-Melbourne-Titusville, FL; Modesto, CA; Bradenton-Sarasota-Venice, FL; Lakeland-Winter Haven, FL, and Cape Coral-Fort Myers, FL.
