120.5.1 Guard Cable

Performance Expectation

Guard cable sections shall be functional, visible, without any structural damage and have vegetation control.

Performance Measures

Visual inspections will be conducted on randomly selected tenth-mile segments in the spring and fall to determine if the guard cable sections look good and are performing as intended.

Performance Objectives

100% of the guard cable shall be properly aligned, properly tensioned, mounted at the proper height, delineated and functioning as intended. Necessary repairs shall be completed within 5 days for emergency repairs and 7 days for routine repairs.

Good
Poor


120.5.2 Guardrail

Performance Expectation

Guardrail sections shall be functional, visible, without any structural damage or corrosion and have vegetation control. All guardrail end sections shall be crashworthy.

Performance Measures

Visual inspections will be conducted on randomly selected interchanges and tenth-mile segments in the spring and fall to determine if the guardrail sections look good and are performing as intended.

Performance Objectives

90% of each section of guardrail shall be properly aligned, mounted at the proper height, delineated and functioning as intended. No more than 20% of the front surface of the railing shall show signs of corrosion. Necessary repairs shall be completed within 5 days for emergency repairs and 10 days for routine repairs.

Good
Poor

120.5.3 Sound Walls and Retaining Walls

Performance Expectation

Sound walls and retaining walls shall be functional, clean, free of structural distress and have vegetation controlled.

Performance Measures

Visual inspections will be conducted on randomly selected tenth-mile segments in the spring to determine if the sound walls and retaining walls look good and are performing as intended.

Performance Objectives

100% of the sound walls and retaining walls are structurally sound and free of graffiti that can be seen from the interstate. Graffiti shall be removed within 30 days of detection.

Good
Poor


120.5.4 Concrete Median Barrier

Performance Expectation

Concrete median barrier shall be functional, free of structural distress and free of vegetation and debris. Repaired sections shall match the typical section of the adjacent barrier wall.

Performance Measures

Visual inspections will be conducted on randomly selected tenth-mile segments in the spring to determine if the concrete median barriers look good and are performing as intended.

Performance Objectives

100% of the concrete median barrier shall be in place and free of structural distress. Necessary repairs shall be completed within 14 days of detection.


Good
Poor


120.5.5 Impact Attenuators

Performance Expectation

Impact attenuators shall be properly installed, delineated and function as intended.

Performance Measures

Visual inspections will be conducted on randomly selected tenth-mile segments in the spring to determine if the impact attenuators look good and are performing as intended.

Performance Objectives

100% shall be properly installed, show no signs of major damage and function as intended. Necessary repairs to the attenuator devices shall be completed within 5 days of detection.

Good
Poor


120.5.6 Fence

Performance Expectation

Chain link fence located between the interstate roadway and an outer road shall be functional and free of vegetation and litter.

Performance Measures

Visual inspections will be conducted on randomly selected tenth-mile segments in the spring to determine if the fencing components look good and are performing as intended.

Performance Objectives

All fences shall be in good repair and functioning as intended. No more than 20% of fabric shall show signs of corrosion or damage.
