Infrastructure Condition

The Federal Highway Administration (FHWA) requires that all states and Metropolitan Planning Organizations (MPOs) measure bridge and roadway pavement conditions. This is 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, 490 of which are located on the National Highway System (NHS), maintaining their safety and functionality 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?

The 2-year target is based on an average of the most recent two years of bridge condition data. For the 2020 2-Year target, 2018 and 2019 data were used.

The 4-year target is based on an average of the most recent four years of bridge condition data. For the 2022 4-Year target, 2018-2021 data will be used.

What Determines Pavement Condition?

Performance ratings of good, fair, or poor condition for pavement are determined by the Federal Highway Administration (FHWA). It uses 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 based on 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 2019, more than 2,200 centerline miles of pavement were rated based on roughness, faulting, cracking, and rutting. Of these centerline miles, 930 were located on the NHS.
