As crews dig in to the Delridge Way SW/SW Trenton Street intersection work this weekend, plans are underway to tackle Phase 2 of the Delridge Paving Project – from SW Trenton to SW Thistle streets. During the second phase, southbound traffic will be detoured to 35th Avenue SW; that’s because Trenton and Thistle streets east of Delridge are not arterials (hence 16th Avenue SW isn’t a southbound detour option). Throughout the project northbound traffic will be maintained – aside from intersection work, which is planned for weekends to reduce commute impacts. During Phase 4, SW Holden to SW Myrtle streets, crews will maintain both northbound and southbound Delridge Way SW traffic.
With the current schedule it looks like crews can start mobilizing for Phase 2 Mid-March. They’ll begin with moving equipment northward and saw-cutting the pavement in preparation for removal. Meanwhile, this week, crews poured concrete all along Delridge Way SW between SW Henderson and SW Trenton streets.

The Delridge Paving Project began January 10, 2013 with construction from just slightly south of SW Henderson Street to SW Trenton Street (Phase 1). The first of the two intersections was completed in just under two days (24 hours of that was concrete curing time), with crews working around the clock February 8 – 10. Pavement and concrete work is weather dependent, so recent rain bumped the schedule for Trenton to this weekend. This go ’round crews started a bit earlier, with pavement removal on the east side of the intersection taking place Thursday, February 28. That pre-work will reduce night-time noise this weekend and allow the concrete pour to begin earlier on Saturday.
Besides rebuilding most of the roadway between SW Henderson and SW Orchard streets, crews are also installing new storm water detention capacity beneath Delridge Way SW as well as upgrading and building new curb ramps to consistently meet accessibility standards.
Each of the five planned phases on this project is expected to take between two and three months to complete. The entire project is expected to be substantially complete by December of 2013 and is part of a larger effort to maintain Seattle’s major arterial asphalt and concrete roadways.
