More than 55000 USA bridges structurally deficient

INDIANAPOLIS, Ind -They're a familiar sight on every commute, but now a new study says thousands of American bridges are in disrepair.

The inventory of structurally deficient bridges only decreased by 0.5% in a year's time.

The association analyzed recently released 2016 data from the National Bridge Inventory from the United States Department of Transportation, which says that nationally, almost 56,000 bridges throughout the country are considered structurally deficient.

"America's highway network is woefully underperforming", said Allison Premo Black, the group's chief of economics who conducted the analysis. "It is outdated, overused, underfunded and in desperate need of modernization". If that's all the improvement that can be gained in 12 months, the group says it would take more than 20 years to improve or replace all of the bridges on the list. And while the nation's inventory of structurally deficient bridges has declined 0.5% since 2015, it would take more than two decades to replace or fix all of them if the current pace holds.

During the Presidential campaign, Donald Trump focused on the nation's "crumbling infrastructure" as one of his priorities.

Norwalk's Yankee Doodle Bridge on I-95, which spans the Norwalk River, is the state's most heavily traveled structurally deficient bridge. They are rated on a scale of zero to nine-with nine meaning the bridge is in "excellent" condition.

The ARTBA report is presented through an interactive map of the United States, in which each state is color-coded based on the percentage of structurally deficient bridges it contains. The information was compiled into ARTBA's 2017 Bridge Report. The District of Columbia (9), Nevada (31), DE (43), Hawaii (64) and Utah (95) have the least. In 2007, a span of an I-35 bridge in Minneapolis collapsed during rush hour, killing 13 people and injuring 135.
