Typical temporary stream crossing methods and their applicability.
Link to this table
Stream crossing type | Applicability | Limitations |
---|---|---|
Temporary bridge |
|
Use in large channels may require pier(s) or other supports, which increase disturbance to stream (see Construction recommendations and specifications) |
Temporary culvert (pipe) |
|
|
Temporary ford (drive-through) |
