Infrastructure Condition
The Federal Highway Administration (FHWA) requires that all states and Metropolitan Planning Organizations (MPOs) measure bridge and roadway pavement conditions to establish performance targets to keep roadway infrastructure in a state of good repair.

Bridge Condition
With more than 2,000 bridges in the OKI region, 540 of which are located on the National Highway System (NHS), maintaining the safety and functionality of those bridges is critical to keeping people and goods moving.
What Determines Bridge Condition?
A bridge is in good condition if its deck, superstructure, and substructure were rated in good, very good, or excellent condition.
How is the OKI Region doing?
Since 2017, the number of bridges in both Ohio and Indiana considered to be in “good condition” has increased 3.4% and 4.3%, respectively, between 2017 and 2021. The number of bridges in Kentucky in “good condition” has slightly decreased by 0.6% during the same period.
Bridges considered to be in “poor condition” has stayed relatively flat in Ohio and Indiana between 2017 and 2021, while bridges rated in “poor condition” in Kentucky have increased.

Pavement Condition
What Determines Pavement Condition?
Performance ratings of good, fair, or poor condition for pavement are determined by FHWA using a combination of several metrics derived from data elements collected by state DOTs and reported to the Highway Performance Monitoring System (HPMS).
These metrics collectively provide a way to quantify pavement condition in terms of roughness and cracking for all pavement types, rutting for asphalt pavement surfaces, and faulting (misalignment between slabs) for jointed concrete pavement surfaces.
Roughness affects users’ travel speeds, safety, comfort, and transportation costs. Cracking, rutting and faulting are considered surface indicators of structural deterioration in different pavement types.
How is the OKI Region doing?
In 2021, more than 1,500 centerline miles of pavement were rated based on roughness, faulting, cracking, and rutting. Of the 1,500 centerline miles, 702 were located on the NHS.
