Deficient and Functionally 
Obsolete Bridges 
An Overview
There are more than 600,000 bridges and roads in the United States. However, 
many of them are structurally deficient and functionally obsolete. Clearly, bridges 
and roads are crucial to the nation’s transportation network. Well, in order to 
solve the problem of infrastructure crisis, private transportation infrastructure 
companies invest in bridge infrastructure fund. This process is also known as a 
public-private partnership. Basically, this is an agreement according to which 
private bridge infrastructure companies invest capital to help the government in 
solving the infrastructure crisis in the United States. 
According to a recent survey report by Federal Highway Administration (FHWA), 
approximately 46,0000 bridges are structurally deficient and dangerous for heavy 
vehicles.
