Southeast May Valley Road reopened to commuters Aug. 19.
The King County Department of Transportation completed work to repair the landslide-damaged road more than a week ahead of schedule.
Workers completely closed a section of road between 223rd Avenue Southeast and 229th Drive Southeast beginning July 20 while crews removed unstable soil from the site, rebuilt the roadway and installed new guardrails.
A 2014 landslide damaged the road, requiring its partial closure for more than a year before construction began. Temporary signals directed traffic through the area in alternating directions during that time.
Southeast May Valley Road was supposed to be closed until Sept. 1, but King County officially finished repairs and reopened the roadway at 7 p.m. Wednesday.

After over a year of being reduced to just one lane, Southeast May Valley Road will be closed to all traffic beginning July 20.
The King County Department of Transportation will repair damage done to the road by a landslide in March 2014. The road is expected to stay closed for approximately six weeks.
The affected section of road runs between 223rd Avenue Southeast and 229th Drive Southeast. May Valley Road traffic is being detoured onto Issaquah-Hobart Road Southeast, Newport Way Northwest and state Route 900.

At 10:37 a.m. March 22, one of the largest landslides in the history of the state happened between the towns of Arlington and Darrington and became generally known as the SR 530, or Oso, landslide.
The slide killed 43 people, destroyed more than 40 homes and other structures, and grabbed national attention.

Southeast May Valley Road has been down to only one lane near the 22500 block for months, and it may stay like that for a while.
A March downpour led to a landslide and damaged the road, causing pavement to crack and settle, according to the King County Department of Transportation website. For safety reasons, the county closed the road and installed a temporary signal to shift traffic.
“This was kind of an act of God,” King County road engineer Rick Brater said. “After the prolonged rains we got last winter, we start to see these slides happen. We have a lot of roads that are old, and it’s in these areas where we have found unsteady ground.”

King County Sheriff ordered an emergency closure on a stretch of Cedar River after a landslide May 10.
No injuries and only minor property damage were reported, according to a press release from the Sheriff’s Department. No homes have been evacuated.
Sergeant DB Gates said the landslide was 200 to 250-feet across.
The closure is from the State Route 169 to the Maxwell Road at the Maple Valley Highway and is effective until further notice.

After the devastating Oso mudslide March 22, long-held fears arose in Issaquah.
“It’s scary,” resident Philip Cherian said about the large hill steeply rising over Southeast Black Nugget Road, blocked from the roadway, Home Depot and Fred Meyer by a wall. “We live in the area and drive by there, and you can see water seeping through.”
Rapid earth movement at that site, and at others around town, has long been a concern for the city. Public Works Engineering Director Sheldon Lynne said the city has remained vigilant over the Southeast Black Nugget Road site, performing studies on the private property.
