The Washington State Department of Transportation (WSDOT) has projects starting on Monday and running through the week. These projects include lane reductions, ramp closures, and a full closure on Veterans Drive in Kent.
Road work in western Washington this week
State Route 509 at Port of Tacoma
Monday, July 7 at 7 p.m., crews will remove the center left turn lanes at the intersection of Alexander Avenue East between northbound and southbound State Route (SR) 509 in Tacoma. Drivers can still make left turns onto SR 509 from the left-through lanes.
Additionally, Alexander Avenue East between 12th Street East and northbound SR 509 will be reduced to a single lane in each direction, with access to right turns. The lane reduction will remain in place for approximately one year while crews rebuild the intersection.
This work is part of the . Once complete, this will add six new miles of tolled highway between Puyallup and the Port of Tacoma and build sidewalks and shared-use paths for non-motorized travelers. Completing this unfinished highway will greatly benefit the movement of freight, improve safety, and reduce congestion on local roads and highways in the surrounding area, according to WSDOT.
I-5, SR 516, SR 509 at SeaTac
WSDOT has scheduled lane and ramp closures on I-5, SR 516, and local roads in Des Moines, SeaTac, and Kent starting Monday, July 7, through the morning of Friday, July 11.
The lane and ramp closures on I-5 will allow contractor crews to stripe the roadway. The lane and ramp closures on SR 516 will allow crews to perform work in the median of the roadway. Local road closures will allow crews to install new roadway signs.
This work is part of the聽.

Coming up: I-90/SR 18
the project will resume this month, according to WSDOT.
This will be the second around-the-clock, extended closure of SR 18 under the I-90 bridges to build the northern end of the diverging diamond interchange.
The expanded closure will be a lot like the five-day closure that WSDOT did in early June to build the southern end of the diverging diamond interchange. A lot of work is involved during these closures, including installing drainage and conduit, installing and synchronizing traffic signals, installing new traffic cameras, constructing traffic curbs, and pouring new median islands.
WSDOT will announce the closure dates and detours soon. Once this second closure is done, the roadway will reopen in the diverging diamond traffic pattern.
Ship Canal Bridge
Revive I-5 over resumes July 18, with a full closure on north I-5 between I-90 and Northeast 45th Street. During this closure, the express lanes will remain open 24/7 in the northbound direction.
