June 2025

Final paving and restoration activities planned on S.E. 22nd St, 78th Ave S.E., and S.E. 24th St as early as June 18

Expect single lane alternating traffic and driveway impacts

Starting as early as June 18, crews will begin paving and restoration activities on Southeast 22nd Street, Southeast 78th Avenue Southeast, and Southeast 24th Street.

Grinding the roadway Crews will first grind the roadway to create a flat surface for paving. Grinding is expected to be completed in one day, with driveway access maintained. Residents may hear increased noise and experience vibrations during grinding. Please plan for up to 20 minutes for crews and equipment to complete grinding work in front of your driveway for access.   Crews will start work on one side of the road before switching to the other. Single lane alternating traffic will be in place along S.E. 22nd St, 78th Ave S.E., and S.E. 24th St during this work. Please drive slowly and pay attention to signage and flaggers.

Paving Impact and Temporary Closures Once grinding is complete, crews will begin paving the road as early as June 20. Paving is expected to be completed in one day and needs a few hours to cure.   During paving, crews may need to temporary close the road and redirect traffic around the area.

Parking advisory

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

No parking signs will be in place, and crews will alert residents whose driveways will be impacted on 78th Ave S.E. and S.E. 22nd St. If you plan to leave your home during permitted hours (7 a.m. to 7 p.m.) on June 20, 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 S.E. 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.

What to expect during construction:

• Approved work hours are 7 a.m. to 7 p.m. Monday to Saturday.
  • There is no planned overnight work for permanent repaving in this area.
• All work will be performed in the public right-of-way.
• Noise, dust, and vibrations typical of an active construction project.
  • Grinding will create additional noise and vibrations.
• There will be parking restrictions on both sides of the roadway.
  • Crews will place no parking signs on both sides of the roadway for the duration of this work.
• Flaggers and single-lane alternating traffic during work hours.
• Emergency vehicle access will be maintained.
• Garbage, recycling, composting, and mail service will be maintained.
  • If services are interrupted, please call the project hotline at 425-305-3578.
