Here at Streamline, we are doing our best to support the Gallatin County community during the current pandemic.

We have implemented robust cleaning measures on all of our buses and are asking riders to maintain social distancing when possible.

Face masks are required for all riders (over the age of four) on all Streamline and Galavan vehicles.

We are also asking all passengers to sit six feet apart from other riders. To help promote social distancing, we will continue to run our 1/2-hour frequency service through the MSU winter break.
