Less than two weeks ago, we got a tour of the Spokane Street construction zone alongside the east edge of the West Seattle Bridge, and an update that work on the new 4th Avenue offramp (aka the future Costco route; rendering above) is ahead of schedule. Today, we have another update from SDOT, including the latest on the ramp and also word of a westbound surface shutdown of Spokane St. later this week – read on:

4th Avenue Off-Ramp Construction Progress

Work on the 4th Avenue Ramp is going well. The last of 22 underground
shafts and columns for the off-ramp was completed last week, more than
a month ahead of schedule. Crews will now shift to the replacement of
storm drains, curbs, sidewalks and new concrete paving on lower
Spokane eastbound, and to the superstructure that will support the
ramp roadway.

In addition, work on the water quality vault just west of the
intersection of 6th Avenue S and S Spokane is expected to finish up
during the week of June 8.

Upcoming Traffic Impacts

This week, June 1 through 4, crews will be working between First
Avenue S and East Marginal Way along westbound Spokane, doing
subsurface investigations. On Monday and Tuesday (June 1 & 2) the
right lane on westbound Spokane will be closed beyond the First Avenue
on-ramp as far as East Marginal Way, leaving one travel lane open. On
Wednesday and Thursday nights (June 3 & 4) there will be a full
closure of westbound Spokane between First and Colorado from 6 p.m. to
7 a.m. Access to the westbound on-ramp to the Spokane Viaduct at First
Avenue will be maintained.

During the full closure Wednesday and Thursday nights, all vehicles
turning onto westbound Spokane from First Avenue will be directed onto
the on-ramp. Vehicles wanting to access East Marginal Way or Harbor
Island from First Avenue can use Hanford.

In mid-June QWEST will start relocating lines in the eastbound Spokane
roadway between East Marginal Way and First Avenue. Access will be
maintained throughout and traffic impacts are expected to be minor.

Starting mid-July, eastbound Spokane will be closed to through traffic
between East Marginal Way and First Avenue, for approximately 12
weeks. Local access will be maintained. More information on schedule
and impacts will be available in the coming weeks.
