Roads & Transportation
Transportation in Big Sky is complex — responsibility is shared between BSOA, Rural Improvement Districts, the counties, and the state. We've put it all in one place.
Who maintains my road?
The answer depends on where your property is and what type of road it is. Here's how it breaks down.
BSOA-Maintained Roads
BSOA maintains certain roads and common area infrastructure within its jurisdiction. Annual member assessments fund winter road maintenance, street lights, speed control, and road signs across BSOA-managed roads.
Rural Improvement Districts
Most Big Sky neighborhood roads are maintained through Rural Improvement Districts — special assessment districts that collect funds for road upkeep. Your RID is typically listed on your property tax bill. BSOA is currently leading a major effort to consolidate and improve RIDs across Big Sky, including a "Global RID" initiative on the Madison County side.
County Roads & State Highways
Some roads in Big Sky are maintained by Gallatin County or Madison County Road & Bridge departments. Lone Mountain Trail (Highway 64) is a state highway maintained by Montana Department of Transportation (MDT). Big Sky spans both Gallatin and Madison Counties.
Contact the BSOA office with your property address and we'll point you to the right answer — even when that answer isn't us. Helping owners navigate Big Sky's organizational structure is one of the most important things we do.
RID Improvement Project
BSOA believes Big Sky's transportation infrastructure is lagging behind population growth and real estate development. In 2026, the Board made improving the RID system a top priority.
Global RID Initiative
BSOA is working with Gaston Engineering to design a consolidated "Global RID" on the Mountain in Madison County that would cover maintenance on all arterial roads — potentially reducing costs for property owners currently paying into multiple overlapping RIDs.
Bridge Repair & Funding
835 properties in the Little Coyote Road area are part of a discussion about bridge repair funding. BSOA's position is to keep this out of general dues increases and instead create a targeted bridge-focused RID for the affected neighborhood.
Speed & traffic calming
BSOA has taken an active role in traffic safety within its jurisdiction. Following a traffic calming study on Little Coyote Road, BSOA facilitated the installation of driver feedback signs, which have proven effective at reducing speeds. BSOA also worked with the Little Coyote Traffic Safety Group to install speed tables on Little Coyote Road — requiring a Gallatin County ordinance amendment.
Construction noise must be limited to 7 AM – 7 PM. Heavy machinery must end operations by 5 PM. Report violations to the BSOA office.
