Tomorrow (Saturday, May 25) you have one more chance to talk with SDOT reps in person about the Highland Park Way hill project – a proposal to remove one downhill motor-vehicle lane and replace it with a protected bike lane, an expanded multi-use path, or (eventually) both. SDOT will be at the Delridge Farmers’ Market (9421 18th SW) 10 am-2 pm Saturday. Meantime, as we reported yesterday, attendees at this month’s HPAC meeting had some questions the SDOT reps were unable to immediately answer – so we sent some of those questions to the department, and got answers late today, as follows:
WSB: “What are the cost estimates of the three options? … And how much money has been spent so far on this very early stage of the project?”
SDOT: “We are engaging the community to shape the scope before we develop draft cost estimates for the options. Generally speaking, Option 1 (protected bike lane) has fewer construction needs since it removes a travel lane and adds concrete barriers. Option 2 (multiuse path) has more complex construction needs since it involves moving a curb line, potential drainage work, and a wider landscape buffer and path. So far, we have spent $145,000 for this project.”
WSB: “(SDOT reps at the meeting) had the current car traffic data. What is the most recent bicycle usage and pedestrian usage data for that section of HP Way?”
SDOT: (Provided table as seen below)
“We plan to collect additional data this summer.”
WSB: “It’s oft-cited ‘if you build the infrastructure (for riders) they will come.’ So it was asked (at the meeting), what is the bicycle usage data for other semi-new lanes in West Seattle, like the Delridge lane post-Delridge rechannelizing?”
SDOT: “We have not measured the bicycle usage on Delridge since the project was completed. We do have data from the West Marginal Way SW Safety Corridor Project, gathered from August-October last year:
“·Weekday bike volumes have increased by 144% from an average of 103 bikers before the project was installed to an average of 251 daily bikers. Weekend bike volumes have increased by 53%.
“·The number of people walking or using a mobility assistance device (like a wheelchair or accessibility scooter) increased significantly, 96% on weekdays and 91% on weekends.
“Here are a few local and national studies showing the effect of bike lanes:”

Those aren’t all the questions HPAC attendees had, just the ones we asked SDOT in followup, so watch for more info from HPAC. Meantime, whatever you think about the project, you can also comment – June 15 is the deadline – via this survey, or via email at HighlandHolden@seattle.gov, or via voicemail at 206-900-8741.
