Overnight work in the Magnolia Bridge/Smith Cove area next week

July 2nd, 2014 · No Comments

King County’s contractors are constructing a new combined sewer overflow (CSO) control facility in the Smith Cover/Terminal 91 area of South Magnolia. This 1.5-million-gallon underground tank will store excess flows of stormwater and sewage when heavy rains fill pipes, reducing untreated overflows to Puget Sound. A 3,000-foot long gravity sewer pipeline will carry excess flows from 32nd Avenue West to the storage tank on 23rd Avenue West.

From Monday, July 7 through Friday, July 11, as part of this work King County’s contractor will install a sewer line under the Magnolia Bridge to connect the CSO facility to the County’s existing sewer line on Port of Seattle property north of the bridge. This work will require trenching through the on- and off-ramps, which will be closed one at a time.

This work will be performed overnight from 7 p.m. to 7 a.m. during lower traffic periods. During this time, access to the Elliott Bay Marina, Palisade and Maggie Bluffs restaurants via the Magnolia Bridge will be maintained. Travel to and from 15th Avenue West and the Magnolia community will also be maintained.

What you can expect during July 7 to July 11 overnight detours:

  • Detours around Magnolia Bridge ramps for several nights
  • Flaggers and signs to direct motorists, pedestrians, and bicyclists around closure
  • Metro Transit routes 19, 23, and 33 will maintain regular service
  • Traffic delays

Use caution, stay safe

Drive slowly through the work area and follow directions from flaggers
