Bridges

With over 2,300 bridges in the OKI region, maintaining the safety and functionality of those bridges is critical to keeping people and goods moving. “Functionally Obsolete” is a status used to describe a bridge that is no longer by design functionally adequate for its task. Reasons for this status include that the bridge doesn’t have enough lanes to accommodate the traffic flow or it may not have space for emergency shoulders.

Functionally Obsolete does not communicate anything of a structural nature. A Functionally Obsolete bridge may be perfectly safe and structurally sound, but may be the source of traffic jams or may not have a high enough clearance to allow an oversized vehicle. “Structurally Deficient” is a status used to describe a bridge that has one or more structural defects that require attention. This status does not indicate the severity of the defect but rather that a defect is present.

Map of Bridge Ratings


Sufficiency Rating

The bridge sufficiency is a method of evaluating highway bridge data by calculating four separate factors to obtain a numeric value which is indicative of bridge sufficiency to remain in service. The result of this method is a percentage in which 100 percent would represent a entirely sufficient bridge and zero percent would represent an entirely insufficient or deficient bridge.

Sufficiency Rating is essentially an overall rating of a bridge’s fitness for the duty that it performs based on factors derived from over 20 NBI data fields, including fields that describe its Structural Evaluation, Functional Obsolescence, and its essentiality to the public. A low Sufficiency Rating may be due to structural defects, narrow lanes, low vertical clearance, or any of many possible issues.

Functionally Obsolete

Functionally Obsolete is a status used to describe a bridge that is no longer by design functionally adequate for its task. Reasons for this status include that the bridge doesn’t have enough lanes to accommodate the traffic flow, it may be a drawbridge on a congested highway, or it may not have space for emergency shoulders. Functionally Obsolete does not communicate anything of a structural nature. A Functionally Obsolete bridge may be perfectly safe and structurally sound, but may be the source of traffic jams or may not have a high enough clearance to allow an oversized vehicle.

Structurally Deficient

Structurally Deficient is a status used to describe a bridge that has one or more structural defects that require attention. This status does not indicate the severity of the defect but rather that a defect is present. Please see the Structural Evaluation and the Condition ratings of each bridge Deck, Substructure, and Superstructure for details of the nature and severity of the defect(s).

Pavement Condition

Our region boasts a robust roadway network of over 9,000 miles, largely built during the 20th century.  We are faced with the challenge of preserving these thousands of miles of pavement across all eight counties. Today, nearly 76% of our interstate miles and 32% of non-interstate miles are considered in good condition.
