Eds.: The report’s Appendix includes the following data for the Interstate system in all 50 states:  pavement and bridge conditions, congestion levels, fatality rates, lives saved annually, and travel trends including Interstate use by large trucks.

Washington, DC –California’s Interstate highways are among the most congested and deteriorated in the nation as the U.S. Interstate marks its 60th anniversary this week. According to a new report released today by TRIP, a Washington, DC based national transportation organization, 85 percent of California’s urban Interstates are congested during peak travel times, the highest rate in the nation. California’s Interstates carry more than 19,000 vehicles per lane mile each day, the highest rate of travel in the U.S. In addition to crowding and congestion, California’s Interstate highways are the second most deteriorated in the nation, with 30 percent of pavement in poor or mediocre condition.

The TRIP report, The Interstate Highway System Turns 60: Challenges to Its Ability to Continue to Save Lives, Time and Money finds that the Interstate Highway System faces increasing congestion, unprecedented levels of travel – particularly by large trucks – and insufficient funding to make needed repairs and improvements.  The nation’s most critical transportation link continues to save lives with its enhanced safety features and is largely well-preserved, but an aging Interstate system will increasingly require more long-term, costly repairs.

The chart below details the top 10 states whose Interstate systems have the largest share of pavements in poor and mediocre condition, the highest urban share that are congested, and the highest rate of travel per lane mile.

"These are not rankings that bode well for the future of our state. The Interstate system has made a significant contribution to California's economy and quality of life for 60 years, but that contribution is diminishing each year as we continue to ignore needed investment in our transportation infrastructure,” said Will Kempton, executive director of Transportation California.  

While the Interstate Highway System represents only 2.5 percent of lane miles in the U.S., it carries 25 percent of the nation’s vehicle travel. The system is increasingly congested, with truck travel growing at a rate twice that of overall Interstate travel. And, while the nation’s Interstates tend to be in better condition than other roads and bridges, the aging system lacks the required funding for needed improvements and repairs.

“The culmination of overdue infrastructure maintenance and lack of capital investment into California’s transportation infrastructure will continue to define our metropolitan cities and paint the state in a negative light among locals,” said Tom Holsman, CEO of the Associated General Contractors of California. “Gridlock is at an epic high and travel in California will only increase in the coming years. It is imperative a viable solution for funding is not only met but sustained.”

The current backlog of needed improvements to the Interstate Highway System, as estimated by the U.S. Department of Transportation, is $189 billion. The nation’s current transportation investment is less than two-thirds (61 percent) of the amount needed to keep Interstates in good condition and make the improvements necessary to meet the nation’s growing need for personal and commercial mobility. And, while the recently enacted federal surface transportation program, the Fixing America’s Surface Transportation (FAST Act) provides a modest increase in spending, it lacks a long-term, sustainable revenue source. By 2020 the annual shortfall into the nation’s Highway Trust Fund will be $16 billion annually.

“The United States moves in large part thanks to the efforts of many elected officials, organizations and citizens whose shared foresight led to the construction of the national interstate system,” said Bud Wright, executive director of the American Association of State Highway and Transportation Officials. “Now, as we commemorate the 60th anniversary of the Interstate act, it’s clear that our investments in preserving the system are not keeping up even as our nation continues to grow.”

Since 2000 travel on the Interstate system is increasing two times faster than new lane capacity is being added. As a result, 43 percent of urban Interstate highways are considered congested during peak hours and the average annual amount of travel per Interstate lane mile increased by 11 percent from 2000 to 2014. Eighty-five percent of California’s urban Interstates are congested during peak travel times, the highest rate in the country. The state also has the highest rate of daily travel per lane mile on its Interstates. Across the nation, travel by combination trucks on the Interstate increased by 29 percent from 2000 to 2014, more than double the 14 percent rate of growth for all Interstate vehicle travel during the same period. Combination trucks make up 17 percent of rural Interstate travel in California.

“It's hard to believe it's been 60 years since the Interstate Highway System was developed,” said Ed Mortimer, executive director for transportation infrastructure at the United States Chamber of Commerce. “The vision of President Eisenhower has enabled economic mobility throughout our nation and showed we can accomplish big things.  As we work to maintain, and in many cases rebuild this great system, let's continue to think big as we work to fund and finance an improved, smarter network.”

In 2015 vehicle miles of travel on the Interstate Highway System was four percent higher than in 2014 and through the first three months of 2016 travel on the Interstate Highway System was five percent higher than during the first three months of 2015.

“Drivers are frustrated with the condition of the nation’s transportation system,” said Jill Ingrassia, AAA’s managing director of government relations and traffic safety advocacy. “While a record 36 million travelers plan to hit the road for Independence Day weekend, nearly 70 percent are concerned that roads and bridges are not in great driving condition. AAA urges lawmakers to keep their eye on the ball to identify a sustainable funding source to maintain and improve our Interstate system for the future.”

The design of the Interstate – which includes a separation from other roads and rail lines, a minimum of four lanes, paved shoulders and median barriers – makes it more than twice as safe to travel on as all other roadways. Nationwide, the fatality rate per 100 million vehicle miles of travel on the Interstate in 2014 was 0.54, compared to 1.26 on non-Interstate routes. In California the non-Interstate fatality rate was more than double the Interstate fatality rate – 0.52 versus 1.07. TRIP estimates that the Interstate Highway System saved 5,359 lives nationwide in 2014 and 481 lives in California. This estimate is based on the number of additional fatalities that would have occurred had Interstate traffic been carried by other major roadways, which often lack the safety features common to Interstate routes.

While the condition of U.S. Interstate pavement and bridges is acceptable, some deficiencies exist. Twelve percent of Interstate highways are in poor or mediocre condition. Three percent of Interstate bridges are structurally deficient and an additional 18 percent are functionally obsolete. Structurally deficient bridges have significant deterioration of the major components of the bridge, while functionally obsolete bridges no longer meet modern design standards, often because of narrow lanes, inadequate clearances or poor alignment.  In California, four percent of Interstate bridges are structurally deficient and 15 percent are functionally obsolete.

“The long-term vision that helped establish the current Interstate system 60 years ago is needed again today,” said Will Wilkins, TRIP’s executive director. “In order to maintain personal and commercial mobility, transportation investment and a sustainable, long-term funding source for the federal surface transportation program must remain a priority.”
