Beginning on May 6, a seven-mile portion of the Grayback Road (Forest Service Road 4611) will be closed for culvert replacement. The closure area starts at FSR 4611 at its junction with State Highway 46 and ends at the junction of FSR 4611 with FSR 4611070, from milepost 0.0 to milepost 7.2. The junction of FSR 4611 with State Highway 46 is approximately 12 miles east of Cave Junction on State Highway 46, just past the Grayback Campground.

Detour Option #1: Continue 2 miles on State Highway 46 past the 4611 junction to the 4613 junction, take FSR 4613 6.9 miles to its junction with FSR 4611070, and continue 3.3 miles on the 4611070 until it reconnects with the 4611 above the closure.
Detour Option #2: Continue on State Highway 46 past the 4611 junction approximately 7 miles to the 4611960 junction, take the 4611960 road 2.9 miles to its junction with FSR 4611070, and continue on the 4611070 3.4 miles until it reconnects with the 4611 above the closure.
