SR 167 Completion Project - Construction

August update: I-5 closures coming the weekend of August 28 and August 29

The most dramatic sign of progress to date on the 167 Completion Project will be the installation of 10 giant bridge girders that will span I-5 and form the new 70th Avenue East Bridge in Fife.

Moving the girders into place requires a full closure of I-5, scheduled for consecutive overnights Friday, August 28 and Saturday August 29. Both directions will close between 54th Avenue East in Fife and SR 18 in Federal Way so crews can safely move cranes on to the highway and lift ten 220-foot-long girders into place.  

Lane closures start as early as 8 p.m., with all lanes of I-5 closing at 11 p.m. both Friday and Saturday nights. There is potential for significant backups which is why travelers are asked to avoid the area and reschedule discretionary trips during the times listed below.

Friday, August 28 to Saturday August 29

  • I-5 NB and SB lane closures begin Friday at 8 p.m.
  • All lanes closed on I-5 at 11p.m. between 54th Avenue East in Fife and SR 18 in Federal Way
  • Lanes begin reopening Saturday at 8 a.m.
  • All lanes reopen by noon Saturday

Saturday August 29 to Sunday August 30

  • I-5 NB and SB lane closures begin Saturday at 8 p.m.
  • All lanes closed on I-5 at 11 p.m. between 54th Ave East in Fife and SR 18 in Federal Way
  • Lanes begin reopening Sunday at 8 a.m.
  • All lanes reopen by noon Sunday

Detours

Drivers who must travel between Seattle and Olympia during overnight hours of Friday, August 28 and Saturday, August 29 are advised to use SR 18, SR 167, and SR 512, which can accommodate the most traffic. The SR 99 detour provides local access back to I-5. Southbound I-5 travelers headed to downtown Tacoma, Gig Harbor or points beyond will want to consider the SR 99 detour.

Ramp closures

Ramps to and from the work zone will be closed during nighttime and overnight hours Friday August 27 and Saturday, August 28. Hours vary, but ramp closures start as early as 7 p.m., reopening by 10 a.m.

Tacoma, SR 16, or points beyond will want to consider the SR 99 detour.

Additional lane closures after girder placement

Once the girders are in place, overnight travelers can expect lane closures on both directions of I-5 weeknights within the work zone Aug. 31 through Sept. 3.  Crews will be finalizing construction and protecting I-5 below the bridge deck.

About the SR 167/70th Avenue East Bridge project

The SR 167 / 70th Avenue Bridge project is part of a larger effort to complete SR 167 and improve connections to I-5 and the Port of Tacoma. The new four-lane bridge replaces a two-lane bridge and provides a 12-foot wide path for pedestrians and bicycles. WSDOT will remove the existing 70th Avenue East bridge as part of the next stage of construction. The project also includes a new roundabout at the 70th Avenue East/SR 99 intersection, a new Interurban Trail parking lot and several hundred feet of new trail.
