Nearly 56,000 bridges called structurally deficient

The American Road and Transportation Builders Association (ARTBA) list of 55,710 deficient bridges includes high-profile spans such as Throgs Neck in New York, Yankee Doodle in Connecticut and Memorial Bridge in Washington, D.C.

The list is based on Transportation Department data. The department scores bridges on a nine-point scale, and while the deficient ones might not be imminently unsafe, they are classified in need of attention.

More than one in four bridges (173,919) are at least 50 years old and have never had major reconstruction work, according to the ARTBA analysis. State transportation officials have identified 13,000 bridges along interstates that need replacement, widening or major reconstruction, according to the group.

“America’s highway network is woefully underperforming,” said Alison Premo Black, the group’s chief economics who conducted the analysis. “It is outdated, overused, underfunded and in desperate need of modernization.”
