Project Update – January 5, 2012

The Rainier Corridor Project Has Reached Substantial Completion

The Seattle Department of Transportation (SDOT) and its contractor would like to thank you for your cooperation and patience while we completed this necessary work.  We hope you enjoy the improvements to Rainier Avenue South and 51st Avenue South.

Please contact the project phone line at (206) 972-6198 for James Sido, Community Communications Officer, or email


Project Overview:

The Seattle Department of Transportation (SDOT) will repave two sections of Rainier Avenue S; a large section of 51st Avenue S; and a one block section of S Henderson Street in 2011.  The work is all part of the 2011 Rainier Avenue S Corridor Paving Project.

The project is funded by the “Bridging the Gap” transportation levy approved by Seattle voters in November 2006. 

Project Description:

This project will resurface sections of the roadway and make other street-related improvements along the Rainier Avenue corridor and adjacent areas.  Benefits include:

  • New asphalt pavement
  • Sidewalk repair and replacement
  • New and upgraded curb ramps to improve travel for wheelchair users
  • Installation of environmentally friendly drainage facilities

Project Locations: 

  • Rainier Avenue S - S Walden Street to S Alaska Street (Phase 1)
  • Rainier Avenue S -  S Austin Street to S Cloverdale Street (Phase 2)
  • 51st Avenue S - Rainier Avenue S to S Bangor Street (Phase 3)
  • S Henderson Street – Rainier Avenue S to 52nd Avenue S (Phase 4)

Project Locations – Sidewalk Reconstruction Only:

  • Rainier Avenue S - S Alaska Street to S Edmunds Street (Phase 5)
  • Rainier Avenue S -  S Henderson Street to S Baron Street (Phase 6)

Project Schedule:

Construction is scheduled to begin in early July 2011 and be completed in November 2011.  Construction will be phased to better manage traffic and disruptions.  Phases 1 through 4 will not be under construction at the same time.  More detailed schedule information will be provided during construction. 

What to Expect During Construction:

  • Lane closures during off-peak hours*
  • Temporary pedestrian detours
  • Temporary bus stop closures
  • Temporary parking restrictions
  • Moderate construction noise
  • Normal work hours of 7 a.m. to 4 p.m. with occasional night and weekend work

*In each of the major phases of construction (phases 1-4), traffic will be reduced to one lane in each direction, up to 24 hrs a day, and as much as seven days per week.  Uniformed police officers will be on hand to help keep traffic moving at key intersections.
