That’s a new, enhanced map from the city webpage for Celebrate Seattle Summer Streets, showing tomorrow’s detours and special features, and giving us new fodder for one more reminder before the big day arrives: From SW Maryland near Don Armeni, to 63rd SW by Cactus, Alki Avenue will be closed to vehicle traffic tomorrow from 9 am-5 pm (except for an inside lane to be used mostly by the King County Water Taxi shuttle – and the city website notes that extra shuttle service will be added). The day begins with the second annual West Seattle 5K Run/Walk, organized by and benefiting the West Seattle High School PTSA, co-sponsored by local businesses including WSB. If you haven’t registered yet, you can sign up tomorrow morning starting at 8 am by the bathhouse. After the WS5K, a full day of activities unfolds along Alki, starting around 11 am – you can see some of the activity locations listed on the map above; one waterfront business that always goes all-out on the “car-free day” is Coastal Boutique – here’s what they’re planning. If you have any questions about vehicle access and parking, here’s a link to the FAQ on the Summer Streets site.
