We have reviewed more than 100 river crossing options for the Burnside lifeline route. We have thoroughly screened these options and narrowed them down to a short list of four alternatives. 

In the environmental review phase of the project, we are studying and documenting the four options, as well as a no-build option. By the end of this process, we will have selected a final option and be ready for the next steps.
