What to expect during construction

As we move into construction, King County will provide information about the schedule of work for each area.

Work has been approved to take place during these times:

  • AUBURN: 7 a.m. to 7 p.m. Monday through Friday, and 9 a.m. to 6 p.m. on Saturday
  • ALGONA: 7:30 a.m. to 6 p.m. Monday through Friday, and 9 a.m. to 6 p.m. on Saturday
  • PACIFIC: 7 a.m. to 7 p.m. Monday – Saturday
  • There may be longer hours, and Sunday and night work.

During construction, you can expect the following:

  • Noise, dust, and vibrations
  • Partial street closures and detours where construction crosses roads
  • Increased truck traffic as crews stage machinery and equipment
  • Access to businesses will be maintained; there may be temporary disruptions
  • Access to homes will be maintained; there may certain times of the day where only walk-in access can be provided
  • After construction, all disturbed areas – including streets and roads – will be restored to pre-construction conditions

Work next to the Interurban Trail

Some work along the Interurban Trail will be on private properties or along property owners’ fence line. We have talked to the property owners and residents about this work.

Work along Seattle Boulevard South and First Avenue

King County will be working in the street on Seattle Boulevard South and First Avenue South. Seattle Boulevard South will be widened after construction is complete and the street is restored and paved. As a result, some mailboxes and sign posts will need to be moved.
