Crossing Information*
Type of Crossing: Culvert(s)
Number of Structures: 1
Structure Shape: Round
Inlet Type: Projecting
Outlet Type: At Stream Grade
Structure Material: Metal
Structure Substrate: Mixture
General Conditions: Major deterioration from corrosion or abrasion (10-50% of the length of structure is rusted through) or cracking or spalling or chipping (large chunks sloughing off, large cracks, exposed metal reinforcement). OR Major shape changes (described above) reducing the capacity of the structure by up to 50%. OR segment disconnection with evidence of water piping under or around the culvert.
Structure Interior: Corrugated
Is Structure Rusted through? No
Dimensions of Structure: Length 60 ft. Width 2.5 ft. Height 2.5 ft.
Percentage Plugged: 41% - 60% Inlet
Percentage Crushed: 61% - 80%
Structure is NOT Perched
Structure Inlet
