4th Ave S Paving Project

Updated January 25, 2017


The Seattle Department of Transportation (SDOT) plans to repave 4th Ave S between S Royal Brougham Way and S Spokane St in 2017. Construction is slated to begin in May, and is likely to take about 6 months to complete.

Before repaving the street, a 2-inch deep layer of the existing asphalt will be ground off. Crews will then evaluate the underlying base asphalt and identify areas where full depth reconstruction is warranted. The curb lanes on both sides of the street will be reconstructed with a full depth asphalt section, in order to better withstand the weight of heavy buses and trucks. Once the full depth repairs have been made, the street itself will be repaved.

The project will also:

  • Replace curb ramps at some intersections to bring them into compliance with the federal Americans with Disabilities Act
  • Replace traffic detection loops in the pavement
  • Install drainage systems at select locations
  • Replaced buckled sidewalks in select locations

Details about the construction schedule and sequencing of construction wont be available until the project has been awarded, probably around the first of the year.
