"미 전국 교량 중 7.7% 구조적 결함 있어" Report: 7.7% of America’s Bridges are “Structurally Deficient” in 2019, Down Slightly YOY

Report: 7.7% of America’s Bridges are “Structurally Deficient” in 2019, Down Slightly YOY

April 8, 2019 Shane Hedmond

Each year, the American Road & Transportation Builders Association (ARTBA) puts out their annual Bridge Report, which highlights the general state of America’s bridges.  Their recently released 2019 report shows that we’re making progress on th structurally deficient bridges across the country, but the association is not satisfied with the speed of repairs.

"미 전국 교량 중 7.7% 구조적 결함 있어" 총 616,087개 교량 중 47,052개     매년, 미국 도로교통건설협회(ARTBA)는 매년 교량 상태를 나타내는 연례 교량 보고서를 내놓고 있다.  그들이 최근 발표한 2019년 보고서는 우리가 구조적으로 취약한 전국의 교량 수에 대해 많은 진전을 보이고 있지만, 협회는 그 개선 속도에 만족하지 못하고 있다.  ARTBA 보고서에따르면 현재 미국에는 616,087개의 다리가 있으며 이 중 47,052개의 다리가 "구조적으로 취약하다"고 한다. 이것은 "주위를 요하는 하나나 그 이상의 구조적 결함이 있다"는 것을 의미한다.  보고서는 지난해 612,677개 이상의 교량 중 구조적으로 부족한 교량은 5만4,249개로 매년 1.2% 감소하여 올해 8.9%에서 7.7%로 감소했다고 밝혔다. 총 결함 교량이 가장 많은 주는 4,675개의 아이오와주가 결함 교량 비율이 가장 높은 주는 23%의 로드 아이랜드주가 차지 했다. 황기철 콘페이퍼 에디터 큐레이터 Ki Cheol Hwang, conpaper editor, curator

There are currently 616,087 bridges in the US, according to the ARTBA report and 47,052 of them have been rated as “structurally deficient. The term signifies that there are “one or more structural defects that require attention.” 

Last year, the report stated that there were over 612,677 bridges and that 54,249 of those were structurally deficient, Year over year, that amounts to a 1.2% reduction in structurally deficient bridges, down from 8.9% to 7.7% this year. 

The ARTBA doesn’t want you to get too excited about the decline, however, because a definition change that became effective on January 1, 2018 has greatly reduced the amount of bridges that can be classified as structurally deficient. Because of that definition change, there are 6,533 bridges rated as structurally deficient on last year’s report that were not included on this year’s, bringing this year’s total reduction down to 567 bridges.

The report states that the rate of work was at its slowest point in five years last year, as the average reduction over that time was 1,700 bridges.

Including the 47K+ bridges listed as structurally deficient, there are over 235,000 bridges that have been identified as needing repaired, amounting to roughly 38% of the total fleet.
