Another “construction starting soon” notice just in – this time, for the permanent protected bicycle lane on West Marginal Way SW. It’s a two-way lane that will run just under half a mile on the west side of the street between the bridge and the Duwamish Longhouse. (The temporary bike lane installed during the low-bridge closure is still in place there.) Along with building the permanent lane, SDOT will be “updating all 17 Duwamish Trail / driveway crossings on the east side of the corridor with signs and pavement markings.” All this is expected to start in early April – weather permitting, SDOT hopes to finish the bike-lane construction over the first two weekends of the month. Here’s the construction notice, which notes: “Construction will be on weekends for the bike lane and on both weekday and weekends for the Duwamish Trail driveway crossing treatments. Trail detours in short sections will be noted on signs. Please dismount bikes and walk around wet paint near driveways.”
BACKSTORY: SDOT first unveiled the bike lane as an option in January 2021. Various rounds of discussion ensued (including a February meeting at which attendees were invited to begin with a “moment of meditation and reflection”). Then the department told the West Seattle Bridge Community Task Force in July 2021 that it would go ahead with the plan. Here’s the design they showed then:
SDOT promised at the time that construction wouldn’t start until after the reopening of the West Seattle Bridge (which has now been back in service for 6 months, following its 2 1/2-year closure). The department says the change will add a few seconds at most to travel times. Other changes will follow as part of the corridor safety project, as noted on its webpage.
