Construction in the Tacoma area

Significant night lane closures ahead for I-5 in Tacoma

Beginning the week of April 20, continued demolition of the Pacific Avenue overpass in Tacoma will require night closures of the northbound Interstate 5 collector/distributor lanes. Later in the week, four-hour night closures are scheduled for all northbound lanes on mainline I-5 in Tacoma. Drivers will follow signed detours.

In addition, triple-lane closures are scheduled for southbound I-5 in Fife over two nights.

Highlights of the closures are listed below. A full list of closures can be found on the Washington State Department of Transportation’s Olympic Region Construction Update Report.

Monday and Tuesday, April 20-21 

  • At 10:30 p.m., drivers will find triple-lane closures on southbound I-5 near Port of Tacoma Road. The lanes will reopen at 4 a.m. each following day.
  • At 11 p.m., crews will close the northbound I-5 collector/distributor lanes. The lanes will reopen at 5 a.m. each following morning.

12:01 a.m. to 4 a.m. Thursday, April 23
All lanes of northbound I-5 will be routed through the northbound I-5 collector/distributor lanes. Drivers will detour via either State Route 7 or Interstate 705.

12:01 a.m. to 4 a.m. Friday, April 24
All lanes of northbound I-5 will be routed through the northbound I-5 collector/distributor lanes. Drivers will detour via either SR 7 or I-705.

Extended closure of Pacific Avenue overpass in Tacoma underway

The Pacific Avenue overpass at Interstate 5 in Tacoma is closed around the clock, through March 2016. Depending on the weather, the overpass could be closed longer. During the closure, the over pass will be demolished and rebuilt as part of WSDOT's I-5 - M Street to Portland Avenue - HOV project. All Pacific Avenue traffic has been detoured. If all goes according to schedule, in March 2016 the Pacific Avenue overpass will reopen to two lanes - one lane of traffic in each direction. Two months later in May, 2016, all lanes will reopen over the new Pacific Avenue overpass.

Work on the Pacific Avenue overpass will also affect traffic on I-5 (see below). Demolition cannot take place over active traffic lanes, therefore much of the demo will occur at night when traffic volumes are lower and crews can close the appropriate ramps and lanes necessary to ensure motorist safety.

Once crews have removed the Pacific Avenue bridge approaches on the northbound side of I-5, they will remove the center spans of the overpass, and finish demolition work on the southbound side of I-5. During this work, in addition to ramp closures, drivers should expect nightly multi-lane closures and rolling slowdowns on I-5.

Around the clock ramp closures

  • The northbound SR 7 on-ramp to southbound I-5 remains closed until spring 2015 for bridge construction.
  • The A-Street on-ramp to northbound I-5/southbound SR 7 remains closed until spring 2017 for bridge construction.

Around the clock road closures

Long-term closure of 20th Street East in Fife in place through 2017. 

A segment of 20th Street East in Fife is closed. The road closure and detour (see below) will be in place, until spring 2017.

The road closure is needed while crews build a new northbound Interstate 5 bridge over the Puyallup River. The bridge, which will be built adjacent to the existing northbound I-5 bridge, will be wider and straighter than the existing bridge, and will feature a new northbound high-occupancy vehicle (HOV) lane. Other improvements will also be made on I-5 between Portland Avenue in Tacoma and the Port of Tacoma Road in Fife.

Public invited to WSDOT open house on proposed I-5 improvements along JBLM corridor

The public is invited to attend an open house to learn more about ideas to help relieve congestion on Interstate 5 between Lakewood and DuPont. Washington State Department of Transportation staff will host the open house where commuters and residents are encouraged to participate and comment.

Proposed corridor improvements
WSDOT officials will be on hand to discuss several possible improvements to the area of I-5 stretching along Joint Base Lewis McCord:
• Build HOV lanes in both directions of I-5 between Lakewood and DuPont.
• Revise and/or relocate three I-5 interchanges (including adding roundabouts at freeway exits):
o DuPont-Steilacoom Road (Exit 119)
o Berkeley Street SW (Exit 122)
o North Thorne Lane Southwest (Exit 123)
• Build a local connector road between Gravelly Lake Drive and Thorne Lane.
• Build a shared-use path along the I-5 corridor.

The open house will be held from 4 to 7 p.m. Tuesday, May 5, at the McGavick Conference Center, located at 4500 Steilacoom Boulevard Southwest in Lakewood.

No formal presentation will be provided. Attendees are welcome to come and go at their leisure during the three-hour event.

Accommodation requests for people with disabilities can be made by contacting the WSDOT Diversity/ADA Affairs team at or by calling toll-free, 855-362-4ADA (4232). Persons who are deaf or hard of hearing may make a request by calling the Washington State Relay at 711.


Tips for Driving Through Work Zones

  • Pay attention - driver inattention is the number one cause of work zone accidents.
  • Leave room between you and the car ahead of you - most work zone accidents involve someone running into the car ahead of them. Drive defensively - be aware of what is happening around you.
  • Merge into the proper lane before you reach the work zone.
  • Don't use cell phones or adjust your radio while driving through the work zone.
