The Milltown State Park Confluence Area will be closed to vehicles from Monday, Aug. 11 through an estimated October 31, 2025, while BNSF Railway Company (BNSF) repairs the railroad bridge located just downstream of the state park on the Clark Fork River.

The road to the Milltown Confluence Area will be impacted by the BNSF construction work, blocking access to the main parking lot and prompting the temporary closure to vehicles. Public access to the area will be walk-in only through the overflow parking on Juniper Road.

Montana Fish, Wildlife & Parks encourages floaters to consider going to a different area while construction is underway. The first public access site downstream from the construction area on the Clark Fork River is Sha-Ron Fishing Access Site (FAS), and it will not be impacted by the project. FWP encourages floaters to put in at Sha-Ron and float downstream, avoiding the Milltown railroad bridge construction area.

Upstream on the Blackfoot River, Weigh Station FAS is the last takeout above the Milltown area, and Turah FAS is the last takeout upstream on the Clark Fork.

FWP says it will work with BNSF to assess the need for temporary river closures for floaters in the Milltown area when construction begins. If closures are needed, FWP will put signs at river access sites upstream and post updates in the news, social media and website.
