2 West Seattle traffic alerts: West Marginal Way & Spokane St. Viaduct

WEST MARGINAL WAY: A traffic alert from the King County Wastewater Treatment Division, about work that’ll be happening over the next few weeks: They’ll have contractors “replacing manholes at the intersections of West Marginal Way SW and Southwest Idaho Street, and West Marginal Way SW and Southwest Alaska Street” starting tomorrow, according to spokesperson Annie Kolb-Nelson. Her advisory continues:

The project could last for up to a couple of weeks, and work hours will be from 9 a.m. – 4 p.m. weekdays, with some night work expected in mid-October to restore sections of West Marginal Way.

Drivers can expect traffic control set up on both sides of the work site to shift traffic around the site. Flaggers will be on hand to ease congestion and accommodate entry and exit to and from facilities near the work sites, including the City of Seattle’s Herring’s House Park parking lot.

Thinking manhole covers generally seemed sturdy enough to last forever, we asked Kolb-Nelson for a little more info about exactly what’s being done. Her reply: “While sewer infrastructure is built to last for many decades, daily wear-and-tear eventually takes a toll, even on non-mechanical equipment like manholes. The workers are replacing the manhole rings and covers in the intersections, which take a lot of stress from traffic, especially heavy trucks.”

SPOKANE STREET VIADUCT RAMP CLOSURE DATE CHANGE: Just found out from SDOT that the date of an overnight ramp closure is changing. The 1st Avenue South offramp from the WESTBOUND SSV will be closed 3 am till 9 am this Saturday morning (October 6th), instead of for a few hours Thursday morning. (We’ll be updating our standing list of traffic alerts – always linked atop the WSB sidebar – ASAP.)
