October 2025

Final paving and restoration activities planned on SE 22nd St, SE 22nd Pl, 78th Ave SE, SE 24th St, and 81st Ave SE as early as October 27

Expect single lane alternating traffic and driveway impacts

Paving Impact and Temporary Closures Once grinding is complete, crews will begin paving the road as early as October 28, with striping scheduled for October 29. Paving is expected to be completed in one day and requires a few hours to cure.   During paving, crews may need to temporarily close the road and redirect traffic around the area. Once crews begin paving, they cannot stop or allow cars to drive on the newly paved roadway.

Parking advisory

During this time, driveways will be inaccessible for three to four hours while the pavement cures. Access to 77th Ave SE will be limited for three to four hours during paving and curing on the south side of SE 22nd St.

"No parking" signs will be in place, and crews will alert residents whose driveways will be impacted on 78th Ave SE and SE 22nd St. If you plan to leave your home during permitted hours (7 a.m. to 7 p.m.) on October 28, consider parking at the Mercer Island Park & Ride. If you have access concerns, please contact the Community Services team at 425-305-3578 or NMEsewer@kingcounty.gov.

Driveway apron restoration

Our project team determined that some driveway aprons (the segment of driveway that connects to the street or sidewalk) along the east side of 78th Ave SE would need to be restored. Crews will restore all driveway aprons on the side of the road where the sewer pipe was excavated and repaired.
