5:44 AM: We’re launching traffic watch earlier than usual because Northbound 99 is still closed in the stadium zone after an overnight car-motorcycle crash. TV crews there say one lane might be open soon – but for now, you can’t use 99; your options are I-5 or surface streets instead. Buses that use 99 have been diverted. Here’s the “live” camera view:

We’ll of course update. SPD says the crash was caused by a wrong-way driver hitting a motorcycle rider, who has life-threatening injuries.

Also this morning:

BIKE TO WORK DAY: It’s Bike To Work Day around Puget Sound, and if you are riding your bicycle this morning, make time to stop at the special “commute station” open until 9 am under the high bridge, co-presented by West Seattle Bike Connections and DIY Bikes.

Alerts for the next few days:

SATURDAY & MONDAY PROTESTS: Saturday is most likely to bring congestion around Don Armeni Boat Ramp and Seacrest Park with kayakers gathering for an on-the-water demonstration because of the Shell rig Polar Pioneer‘s arrival; Monday, an early-morning on-land demonstration is planned, going from the fishing bridge to Terminal 5, which might affect commute-hour travel on and around the low bridge.

SUNDAY, WEST SEATTLE 5K: The first and biggest run/walk of the season on Alki is happening Sunday morning, 9:20 am, with Alki Avenue closed to vehicles (and heed the “no parking” signs) until 11 am or so. Once again, NO “car-free day” festival afterward, for the first time in many years, so the road will fully reopen afterward.

6:01 AM UPDATE: One lane of northbound 99 is now open.

6:48 AM: Both lanes of NB 99 are now open.
