The King County Road Services Division is planning two projects to repair flood-damaged roadways between Fall City and Snoqualmie during late summer/fall of 2017. The two projects are on opposite sides of the Snoqualmie River, on different roads.

SE David Powell Road

Sept. 5, 2017 - Repair work on SE David Powell Road begins Wednesday, Sept. 6, and should last about four weeks.

This project will repair about 300 linear feet of SE David Powell Road about one mile southeast of Preston-Fall City Road. This part of the road has had chronic problems during flooding and storms. The county will build a rock buttress wall; replace a catch basin and a culvert under the roadway; repair the roadway, shoulder, and slope; install new guardrail along the river side of the road; and plant native vegetation.

The total project area will cover about a third of an acre, including space needed for construction, access, and staging. One lane of the road will remain open throughout the project (about four weeks) for two-way controlled traffic and emergency vehicles.

This project will repair about 180 feet along the southwest (river) side of SE Fish Hatchery Road, about half a mile southwest of State Route 202 and a mile west of Snoqualmie. This part of the road developed small failures along the southeast shoulder, next to the Snoqualmie River, due to river scour and storms. A section of the shoulder dropped about six feet, leaving a near vertical cut along the south edge of the roadway.

The county will rebuild the subgrade under two sections of the roadway and install guardrail on the river side of the road. Utilities will be moved before construction begins. This section of the road will be completely closed for about three weeks. Road signs will direct traffic along a recommended detour during the closure.
