FOLLOWUP: Highland Park traffic-calming, round 1, almost done

Even as the Reconnect West Seattle feedback process continues, Highland Park already has had some traffic-calming measures in the works. Last week, Cindy sent us a photo of a sign that’s already installed and waiting along 9th SW – though the speed bumps it mentions aren’t in place yet:

We checked with SDOT on the installation status, and they sent us the map above, saying, “We have completed installing all of the traffic calming measures everywhere except 9th Ave SW, which we are still working to schedule.” As noted on the map, the 9th SW installations are planned as “speed cushions” – here’s the difference, as explained by SDOT:

Speed humps are designed to slow traffic speeds on low volume, low speed streets. They are a solid hump across the travel lane and are installed near streetlights where they will be visible to people driving and biking.

Speed cushions are typically installed where average speeds are 5 mph higher than the speed limit. Speed cushions leave space for emergency vehicles to pass through quickly and are used on designated fire and emergency routes on residential streets.

This project also included the Highland Park Way/Holden traffic signal that was rush-installed right after the West Seattle Bridge closure, after local residents had worked for years to get safety upgrades at that intersection.

P.S. If you live/work/travel through the area, be sure to give your feedback on the neighborhood-specific list of more potential projects, before July 31st.

        I have asked for speed bumps four different times and got the run around  each time .4100 block of 38th SW it is a speedway Signs just do not work

    Are there any plans at all for 16th Ave SW and Holden?  That intersection needs some serious attention to say the least.

    Why doesn’t sdot have cameras at W. Marginal and Highland Pkwy, they’ve got them on all the other detour route?

    • SLEEPLESS IN WEST SEATTLE July 20, 2020 (6:38 pm)

      Great suggestion! I totally agree that we need traffic cameras for both the top and the bottom of Highland Parkway SW hill. I mentioned this in the survey.

    TR, do you know if diverters for side streets along SW Holden St. were considered for the neighborhood at all? 

  • Brenda July 20, 2020 (5:59 pm)

    TR, we are experiencing high volumes of traffic, speeding, and have had 4 accidents on Sylvan Way since the bridge closure.  I have seen focus on Holden and Highland Park Way but nothing for Sylvan way which is the farthest north “cutover” point for the detour.  Who should we be writing to, contacting, to get action?  The survey I took didn’t address Sylvan Way.  Thanks!

    I live on 16th and Holden. Hate the speed bumps, even on the Greenway and I am a bicycle rider. What about that signage at the 7-11, is that allowed by the city?

    As someone who lives on 15th Ave SW with speed humps installed at part of the Delridge-Highland Park Greenway (also now a Stay Healthy Street), the height of them are totally useless.  Neither of these projects have slowed or calmed traffic.  Even prior to the WS Bridge closure, cars would speed down 15th to get around the traffic backed up by the signal at 16th and Holden.  The speed humps need to be at 4 inches higher and then it may slow them down…

    It would be nice if SDOT recognized that the majority of traffic travels along Holden/Sylvan (not over 9th) and that this rushed project included safety features in  Riverview and also  helped us leave our neighborhood.  There are no breaks in uphill traffic on Highland Park Way which moves at such high speeds that accidents are inevitable.

    Here is an idea, improve the arterials you’ve downgraded so you don’t have to do traffic calming on every neighborhood street on the peninsula.

      Crazy talk!

    • Stevie J July 22, 2020 (5:41 pm)

      Downgraded for whom?

      • Matt July 24, 2020 (5:28 pm)

        Traffic volume. 

Sorry, comment time is over.
