The department’s October 14 notice identifies an adjacent trail closure, not a closure of the entire boulevard. People using that segment should plan around the posted work area; the announcement does not name an official detour.
Crews plan to put up advance notices and mark treatment locations. The stated closure includes time for the treatment to dry. The release does not identify the product or provide a separate reopening test, so this article does not add chemical-handling instructions or promise an earlier reopening.
For questions about the work, the city names Bridget Kelsh at Bridget.kelsh@seattle.gov. The announced times are reproduced as local notice times. Because the release does not explicitly identify a time zone, no exact-time deadline record was inferred.
