Any driver who spends enough time on the interstate highway system can speculate about which cities and states have the worst traffic and road conditions, but a recent report from TRIP, a nonprofit that researches transportation trends and needs, reveals its calculation of the worst offenders.
TRIP's report, released Tuesday, coincides with the 65th birthday of America's interstate highway system, concluding that it direly needs repair and investment. The report comes as a national debate over interstate funding rages and the freight market runs hotter than ever before.
“Our rapidly deteriorating infrastructure is a clear and present danger to our nation’s supply chain. Breakdowns in the Interstate Highway System add an annual $75 billion to the cost of freight transportation, and 67 million tons of excess carbon dioxide emissions are released into the atmosphere every year from trucks stuck in traffic congestion,” Chris Spear, president and CEO of the American Trucking Associations said in a statement on TRIP's report. “This report quantifies how severe this crisis has become, and it underscores the urgent need for Congress to make real infrastructure investments that are backed by a fair and equitable user-based revenue source.”
The report is based largely on the findings of a 2019 report prepared by the Transportation Research Board at the request of Congress. TRB is part of the National Academies of Sciences, Engineering, and Medicine. Here's what the report said about America's highways in 2021:
Traffic is back
"During the initial stages of the COVID pandemic, we saw a 45% drop in overall vehicle travel on the nation's interstate highway system, but by this April vehicle travel on the interstate highway system is only 6% below pre-pandemic levels," the report said.
In other words, the pandemic-induced holiday from heavy traffic is mostly over.
States with the worst traffic
California, Maryland, New Jersey, Delaware, and Florida have the worst congestion. California's congestion rate is 40 percentage points higher than the national average of 47%.
States with the worst-paved highways
Thankfully, the state with the most extreme percentage of poor roads isn't one an OTR hauler can visit. Hawaii has 23% of its interstate highway pavement in "poor" condition, according to the report. This runs 20 percentage points higher than the national average of 3%.
Delaware, New Jersey, Louisiana, and New York make up the rest of the top five, though they range from 9% to 6% of interstate pavement in "poor" condition.
Highway design is saving lives
Despite concerns over ailing infrastructure, the TRIP report says that years of certain highway improvements have mostly worked to reduce fatalities.
The report says safety features like the separation from other roads and rail lines, a minimum of four lanes, paved shoulders and median barriers make interstates more than twice as safe as all other roadways.
"The fatality rate per 100 million vehicle miles of travel on the Interstate in 2019 was 0.55, compared to 1.30 on non-Interstate routes. TRIP estimates that additional safety features on the Interstate Highway System saved 6,555 lives in 2019," the report said.
