Typical temporary stream crossing methods and their applicability.

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) |
