Chaffin Creek Road 374, south of Darby, will be closed starting May 1.

Two culverts will be replaced by the Bitterroot National Forest to remove fish barriers and reclaim an estimated mile of Westslope Cutthroat Trout spawning habitat.

The new, larger culverts will also help natural stream flows on Chaffin Creek. The flow capacity will pass 100-year flood events. The road will also be widened, re-graded and drainage will be improved.

The work is expected to take about two weeks, according to Tod McKay, public affairs officer with the Bitterroot National Forest. Road closure signs will be posted at West Fork Road and around the construction areas.
