Tacoma I-5 construction in full swing next week with numerous lane and ramp closures scheduled

Construction crews working for the Washington State Department of Transportation have multiple overnight ramp and lane closures planned for Interstate 5 during the week of Sept. 8. Crews will restripe lanes and ramps along I-5 in Tacoma as part of theI-5: M Street to Portland Avenue – HOV project. 

Beginning at 10 p.m. Monday, Sept. 8, the southbound I-5 exit to State Route 7 and Interstate 705 will close, along with the State Route 167 and Portland Avenue on-ramp to southbound I-5. All ramps will re-open by 6 a.m. Tuesday, Sept. 9. 

In addition, southbound I-5 will be reduced to one lane from the Puyallup River Bridge to I-705 between the hours of 12:01 a.m. and 4 a.m. Tuesday, Sept. 9. 

Beginning at 8 p.m. Tuesday night, the left lane of southbound I-5 and the right lane of northbound I-5 will close between Portland Avenue and I-705. At 11 p.m., the SR 7/I-705 on-ramp to northbound I-5 will close. The ramp will re-open by 4 a.m. Wednesday, Sept. 10. Northbound lanes will reopen an hour later at 5 a.m., while southbound lanes will re-open by 6 a.m. 

The same overnight SR 7/I-705 ramp closure will take place Wednesday night into Thursday morning. 

Last but not least, northbound I-5 will have two lanes closed between M Street and Portland Avenue starting at 11 p.m. on Wednesday, Sept. 10 until 4 a.m. Thursday, Sept. 11. 

As a reminder, the A Street on-ramp to northbound Interstate 705/Interstate 5 is closed until December. A signed detour is in place for motorists. Also, southbound I-5 between Yakima Street and State Route 16 is reduced from four to three general-purpose lanes around the clock for approximately six weeks. Crews have closed the left lane so the median can be rebuilt to carry traffic through the area during future traffic shifts.
