New data this month: Infrastructure Week edition

Counties are leaders in the nation’s infrastructure system. From building and maintaining roads and bridges to providing efficient transit options, counties are a driving force connecting communities and strengthening our economy.


Infrastructure Expenditures

In 2016, county governments invested more than $122 billion on infrastructure and maintaining and operating public works.†


Bridge Ownership

38 percent of all bridges across the nation are owned and maintained by counties.


Structurally-Deficient Bridges

In 2018, there were more than 45,700 bridges classified as structurally deficient and considered to be in poor condition.*


Road Ownership

45 percent of public roads across the nation are owned and maintained by counties.


County Public Road Miles

In total, more than 1.8 million public road miles are county owned.

†Data are from the U.S. Bureau of the Census, Survey of State and Local Government Finance, which provides government finance statistics for two-thirds of counties with county governments.
*Effective Jan. 1, 2018, the Federal Highway Administration changed the definition of structurally-deficient bridges which limits the classification to bridges where one of the key structural elements — the deck, superstructure, substructure or culverts — are rated in poor or worse condition.
