Bridge Inspections / Sufficiency Ratings

5

Oak Hill Bridge - Public Information Meeting, April 30, 2014

• Each bridge is thoroughly inspected by Caltrans

every 2 years and rated on 140 elements

• Given a Sufficiency Rating (SR) score of 0 to 100
• Rating is overall measure of the bridge condition

and sufficiency to remain in service

• Used to determine eligibility for federal funds and

prioritization

Federal Funding Eligibility Criteria

6

• SR < 80 is eligible for Rehabilitation
• SR < 50 is eligible for Replacement

– Oak Hill Road Bridge SR = 46.0 (January 2011 inspection)

• Rehabilitation projects – cannot use any additional

federal aid for 10 years.

• Replacement projects - bridge must be either

structurally deficient or functionally obsolete.

Bridge Sufficiency Terminology

7

Oak Hill Bridge - Public Information Meeting, April 30, 2014

Structurally Deficient: Limitations of the structural condition of the bridge, such as weight limits or load capacity. Functionally Obsolete: Built to standards that are not used today, such as inadequate lane widths, shoulder widths, or vertical clearances to serve current traffic demand. The status of this bridge is Functionally Obsolete.

Why Replace the Existing Bridge?

11

• Bridge is almost at 75-year life expectancy
• Bridge is classified as Functionally Obsolete
• Anticipated 100% federal funding; this funding may

not be available in the future, if the project is postponed

• No County funds are proposed to be used for this

project

• Narrow one-lane bridge restricts emergency access
