People traveling in Lynnwood and Alderwood should plan for overnight closures of southbound State Route 525 and multiple ramps near the Interstate 5/I-405 interchange Tuesday night, May 26, until Friday morning, May 29, and again Sunday, May 31 until Friday morning, June 5.

What to expect
According to the Washington State Department of Transportation (WSDOT), the following closures are from 8 p.m. until 5 a.m. nightly Tuesday, May 26, until Friday morning, May 29:

  • A single lane of southbound SR 525 between SR 99 and Alderwood Mall Parkway.
  • The northbound SR 99 ramp to SR 525.

The following closures are from 10 p.m. until 4:30 a.m. Sunday, May 31 until Friday morning, June 5:

  • Southbound SR 525 between SR 99 and Alderwood Mall Parkway. All southbound SR 525 traffic will have to exit at SR 99.
  • The northbound and southbound SR 99 ramps to SR 525.
  • The southbound SR 525 off-ramp to Alderwood Mall Parkway.

Contractor crews working for WSDOT will grind and repair pavement as part of the SR 525/I-405 Interchange to SR 99 Vicinity – Paving & ADA project. This work will repave roughly two miles in both directions of SR 525 from the I-405 interchange to just south of 148th Street Southwest, as well as eight ramps in the area.

Drivers should expect delays and follow signed detours or use alternate routes. This work depends on dry weather and may be rescheduled.
