HELENA, Mont. — Montana Fish, Wildlife & Parks (FWP) has temporarily closed a section of the Sun River to all public access as a safety precaution during an ongoing bridge replacement project near the Pishkun Road Bridge.

The emergency closure, which went into effect on July 23, restricts access to the river from 500 feet upstream to 500 feet downstream of the bridge site. This means boaters, anglers, swimmers, and other recreationists must avoid this stretch until construction crews complete the work and the area is cleared for safe public use.

A Much-Needed Bridge Upgrade

The Sun River Bridge, also called the Pishkun Road Bridge, is a vital rural crossing that supports local ranchers, farmers, residents, and outdoor enthusiasts traveling through Teton County and Lewis and Clark County. Originally built decades ago, the bridge has experienced significant wear and tear from Montana’s harsh winters and heavy farm traffic.

Replacing the bridge will improve structural integrity and safety for vehicles, farm equipment, and emergency services that rely on the crossing year-round. The project is part of a broader effort by the state to maintain and modernize aging infrastructure that connects rural communities and supports Montana’s agricultural economy.

Impact on Local Recreation and Wildlife

The Sun River is a beloved destination for fly fishing, floating, and wildlife viewing. It supports diverse fish species and provides important habitat for birds, deer, and other wildlife that thrive in the riparian corridor.

FWP officials said the temporary closure is necessary to protect both public safety and the river ecosystem during construction. Heavy machinery, demolition debris, and construction runoff could pose risks if the public were allowed to enter the area.

Outside the closed stretch, the rest of the Sun River remains open for fishing and paddling. Outdoor users are encouraged to use alternative river access points until the project wraps up.

How Long Will the Closure Last?

There is no exact date for reopening yet. The emergency rule will remain in effect until construction is complete and the site is inspected and deemed safe for visitors. If work finishes ahead of schedule, the closure may be lifted sooner. Otherwise, it could remain in place into fall, depending on weather conditions and construction progress.

Investing in Montana’s Future

Rural bridges like this one are critical for moving crops, livestock, and supplies — and ensuring families have reliable access to schools, medical services, and businesses. Infrastructure upgrades like the Sun River Bridge replacement help keep Montana’s rural communities connected and resilient.

Stay Updated

FWP advises river users to check for updates on its website and social media channels for news on when the stretch will reopen. The department also reminds the public to respect posted signs and barriers for their own safety and to avoid interfering with construction crews.
