Crossing Information*
Type of Crossing: Culvert(s)
Number of Structures: 2
Structure Shape: Round
Inlet Type: Projecting
Outlet Type: Freefall into Pool
Structure Material: Metal
Structure Substrate: None
General Conditions: Severe deterioration from corrosion or abrasion (more than 50% of the structure is rusted through) or cracking or spalling or chipping (more than 50% of the structure is compromised). Or Major shape changes (described above) reducing the capacity of the structure by greater than 50%. OR Segment disconnect causing major subsurface erosion/piping and/or partial fill failure and/or sink holes in the fill.
