Frontier West anticipates using crossover traffic patterns and lane shifts during construction to ensure that I 90 traffic does not stop during construction.
- Traffic will be reduced to one lane in each direction.
- Both east and westbound traffic will travel on the same side of I 90.
- Speed limits will be reduced.
- Width and length restrictions will be in place (visit www.511mt.net for the most up-to-date information).
Clark Fork River
The river will remain open, but signage may direct river traffic to one side of the river at certain times.
