Story

King County is set to begin repairs to a section of Southeast May Valley Road severely damaged by a major landslide in 2014. Work will begin Monday, July 20, and will require complete closure of the roadway for approximately six weeks.

The section of Southeast May Valley Road between 223rd Avenue Southeast and 229th Drive Southeast was heavily damaged by a landslide triggered by heavy rain in March 2014. The slide caused the road pavement to crack and sink, reducing access to one lane of traffic to maintain safety.

Work will include excavating unstable soil, building a retaining wall, restoring damaged pavement and installing new guardrail. The project is expected to cost about $1.45 million, with more than 80 percent of the cost covered through federal disaster reimbursement.

Given the complicated nature of repair work, the road will need to be completely closed to vehicles, bicycles and pedestrians to maintain safety.

While construction is underway, traffic will be detoured onto Issaquah-Hobart Road Southeast, Newport Way Northwest and State Route 900.
