Construction on Sammamish’s main artery, 228th Avenue SE, is scheduled to begin Aug. 21 and run through the end of the month.

Work will be done between Southeast 24th and 35 streets and will include grinding off the top layer of pavement, patching, and repaving the surface with a new two-inch layer of hot mix asphalt.

During this work, the road will remain open to traffic. However, the number of lanes will be reduced to one in each direction.

Residents should anticipate delays.

Access to driveways and side streets will be maintained except for brief, intermittent closures that are anticipated to be 15 minutes or less andwill only occur when work is directly in front of the driveways or side streets.

Construction hours are 7 a.m. to 5 p.m. and 8 p.m. to 7 a.m. Work will only take place on weekdays and is scheduled to end Aug. 31.
