58K U.S. Bridges Deemed Deficient

Monday, February 22, 2016

The American Road and Transportation Builders Association (ARTBA) recently designated 58,495 U.S. bridges as structurally deficient—out of a total of 609,539 contenders—and actually 2,754 less than reported last year.

The ARTBA conducts an annual review of bridge conditions in the U.S. and concludes that at the current rate of bridge investment, it would take over 21 years to address the deficient bridges with upgrades or repairs.

The Association released its latest report Feb. 2.

At the current rate of bridge investment, it would take over 21 years to address the deficient bridges with upgrades or repairs.

The Association notes that if placed end-to-end, the deck surface of the nation’s structurally deficient bridges would stretch from New York City to Miami—a total of 1,340 miles.

Inspection and Rating System

To help ensure public safety, bridge decks and support structures are regularly inspected by the state transportation departments for deterioration and remedial measures and are rated on a scale of zero to nine—nine indicating that a bridge is in “excellent” condition. A rating of four or below designates a bridge as structurally deficient.

While these bridges are in various states of deficiency, some less unsafe than others, the purpose of the report, the association said, is to help educate the public and policymakers that there are structural deficiencies that need repair.

Over 200 Million Daily Crossings

The Association estimates that there are nearly 204 million daily crossings on U.S. bridges in need of structural repair, the 250 most heavily traveled of which are listed on the ARTBA website.

“Every year we have new bridges move on the list as structures deteriorate, or move off the list as improvements are made,” said Dr. Alison Premo Black, ARTBA’s chief economist, who conducted the analysis.

Almost all of the 250 most heavily crossed structurally deficient bridges are on urban highways, particularly in California, according to the association. Nearly 85 percent were built before 1970. Iowa (5,025), Pennsylvania (4,783), Oklahoma (3,776), Missouri (3,222), Nebraska (2,474), Kansas (2,303), Illinois (2,244), Mississippi (2,184), North Carolina (2,085) and California (2,009) have the most structurally deficient bridges, the analysis found. The District of Columbia (10), Nevada (35), Delaware (48), Hawaii (60) and Utah (95) have the least.

At least 15 percent of the bridges in eight states—Rhode Island (23 percent), Pennsylvania (21 percent), Iowa (21 percent), South Dakota (20 percent), Oklahoma (16 percent), Nebraska (16 percent), North Dakota (16 percent) and West Virginia (15 percent)—fall in the structurally deficient category.

“Every year we have new bridges move on the list as structures deteriorate, or move off the list as improvements are made,” said Dr. Alison Premo Black, ARTBA’s chief economist, who conducted the analysis. 

On the Positive Side

In the 2015 report, there were 4,625 structurally deficient bridges that were not so classified in 2014, she says. On the positive side, about 7,200 bridges classified as structurally deficient in 2014 were repaired, replaced, rebuilt or removed from the 2015 inventory. The net effect, Black says, is a slow national reduction in the overall number of structurally deficient structures.

About 7,200 bridges classified as structurally deficient in 2014 were repaired, replaced, rebuilt or removed from the 2015 inventory.

Black notes the recently enacted five-year federal highway and transit law provides a modest increase in funding for bridge repairs. 

But “the funding made available won’t come close to making an accelerated national bridge repair program possible,” she said. “It’s going to take major new investments by all levels of government to move toward eliminating the huge backlog of bridge work in the United States.”
