BIKE-TO-WORK DAY TOMORROW: For participating bicyclists, there’s the “commute station” by the west end of the “low bridge” plus, if you’re coming from White Center, or heading through there, two WC stops, Caffé Delia and Dubsea Coffee, all detailed in the preview we published earlier this week.

ALASKAN WAY VIADUCT WEEKEND CLOSURE REMINDER: 11 pm Friday to 5 am Monday, so WSDOT can keep working on reinforcing the section of The Viaduct that the tunnel will go beneath.

SUNDAY CLOSURES/CHANGES ON ALKI: Sunday starts with the West Seattle 5K (co-sponsored by WSB) benefit run/walk at 9 am, and at 11 am, Seattle Summer Streets (aka “car-free day”) – here are the Alki traffic changes you can expect as a result – note that even though the car-free events are on a limited section of the street, the rest of it is ONLY open to residents. Here’s how SDOT explains the plan:

•From 9 a.m. to 11 a.m.: Alki Avenue SW will be fully closed from 63rd Avenue SW to the Don Armeni Boat Launch Ramp for the West Seattle 5K Run/Walk. All parking will be restricted from 63rd to 56th and along the waterside from 56th to the boat ramp.

•From 11 a.m. to 5 p.m.: Alki Avenue SW will be fully closed from 63rd to 56th Avenue SW for the Summer Streets event. Parking will be restricted on both sides of the street during this time.

Access exceptions will be made for emergency vehicles and people with disabilities. After 11 a.m. local access to condos will be allowed from 56th Avenue SW to the Don Armeni Boat Launch Ramp. As in the past, SPD will detour those who do not live in the vicinity from Alki on to California Ave SW until 5 p.m.

(Added Friday morning: The citywide weekend event alerts, here.)

NEXT WEEK AND BEYOND, SPOKANE STREET VIADUCT PLANS: A roundup of what’s ahead for the Spokane Street Viaduct section of the West Seattle Bridge includes two notes looking past next week, before next week’s closure schedule – the switch from eastbound 1st ramp open to eastbound 4th ramp open is not going to happen next week after all; plus, in early June there will be a full=weekend closure of the westbound SSV – read on for complete details from SDOT:

The eastbound off-ramp at Fourth Avenue S has been closed since mid-April, when eastbound traffic was temporarily shifted onto the new viaduct structure in order to make room for repairs and repaving of the bridge deck on the old structure. It had previously been reported that the Fourth Avenue off-ramp would reopen next week (May 22 or 23), however, this has now been delayed. SDOT now expects the Fourth Avenue off-ramp to be open for the morning commute on Wednesday, May 30, at which point the eastbound off-ramp at First Avenue S will close. The First Avenue off-ramp is expected to remain closed for about four weeks.

Looking ahead, all westbound lanes of the Spokane Street Viaduct from I-5 to SR 99 will be closed from 6 p.m. Saturday, June 9 until 5 a.m. Monday, June 11.
