Delridge repaving update: Detour map fixed, thanks to WSB readers

| Delridge | West Seattle news | West Seattle traffic alerts

That’s an updated detour map for Phase 2 of the Delridge Way repaving project, scheduled to take effect sometime next week – probably not before Wednesday, according to SDOT’s LeAnne Nelson, who thanks commenter Jim P for pointing out a problem with the map sent yesterday:

Your readers bring up a good point regarding the map. It shows the right-of-way routes for both 25th and 26th Avenue SW even though parts of what would be the roadway are unimproved. Attached is an updated map. Thank you to your readers for pointing out the issue!

Nelson also addresses an issue that commenter Breeze brought up:

Comments to your Phase 2 story include a question about why we detour to 35th Avenue SW. We strive to detour traffic along arterials, and the only consistent arterials flanking Delridge are the west sides of Trenton and Thistle (east sides of those streets are not arterials) and 35th Avenue SW to link them north/south.

We cannot disallow vehicles from utilizing public streets, but we can encourage arterial use. If speeding is witnessed repeatedly on the street, let us know, and we could place speed tubes to track the problem and potentially request more enforcement in the area. We also strongly suggest neighbors partner with our Neighborhood Traffic Calming Program team to apply for roadway assessment and possible traffic calming measures. Details are at: seattle.gov/transportation/ntcp_calming.htm

Again, provided weather doesn’t get in the way of Phase 1’s completion between SW Trenton and Henderson, Phase 2 of the repaving will start sometime next week along Delridge between Trenton and Thistle, and that’s when the – revised! – detour map will apply. This phase of the project is expected to last about 2 1/2 months.

I am surprise they only worked on the West side (southbound lane) of the road during Phase 1. At no time did they tear up/replace the roadway on the right (northbound) side. I figured they were going to replace ALL of the roadway, and just move the single northbound lane West/East as needed depending on which part of the road they were working on.

Any insight into this? Is it just the West half of the road for the entire project?

YEY! they’re moving on. so happy to be done with the extra 10 billion cars speeding down the treet.

Exactly what Ray said. Are they going to be working on the east side of the roadway? That side has cracks too

From what I’ve seen of the plans, it appears most of the two center lanes will be replaced, except at a few locations where the pavement is still in good shape, from Trenton to Holden. There will only be some pavement replacement in selected areas on both the east and west side parking lanes. The Thistle and Holden intersections will be completely replaced with new pavement. North of Holden the roadway is asphalt, which will be ground off and replaced curb to curb to just north of Orchard. Hope this helps.

Thanks, Marty. This was the same plan during the last extensive repaving project here in West Seattle, Fauntleroy Way, a few years back. We walked the route with then-paving guru Jessica Murphy (who now is leading the seawall project) – she explained that some sections of road don’t need to be replaced, and pointed out how you can tell the difference (concrete roadway sections are placed in “panels). Here’s that story – the explanation is roughly in the second half:

Thank you Ray for your comment. For maintenance projects in the arterial asphalt and concrete program (AAC) the arterials are assessed for life expectancy and current condition. From approximately where Delridge intersects 18th Avenue SW to where it intersects Trenton, the northbound lane was found to be in good condition. There are some cracks in the concrete, but as engineers noted, there hasn’t been differential settlement at the cracks, crack spalling, or multiple cracks in single concrete panels or excessive rutting, as it’s called.

Meanwhile, Phase 2 is set to start March 20th, weather permitting, with just some sidewalk and curb work left in Phase 1.

Sorry, comment time is over.
