When we think of Spring we often think of changes. Like warming tempertures and more sunshine, the budding of new leaves and the birth of new flowers. It also brings new changes to Sound Transit’s Spring service, starting Saturday, March 29th.
This year introduces a brand new ST Express bus route through Federal Way, and adjustments on routes between Snohomish, King, and Pierce counties. Minor adjustments will be added on the 1-Line service between Lynnwood and Angle Lake. May 10th the 2-Line service is set to expand into Redmond.
A lot of exciting additions are being implemented to better serve a growing need for expanded service across the region.
Here’s what’s happening in Kirkland
Sunday, March 30th between 7 a.m. – 3 p.m. the Northeast 70th Street on-ramp to southbound Interstate 405 (I-405) will close, including the right lane on I-405 approaching the area. This closure will allow the Washington State Department of Transportation (WSDOT) crews to repair damaged guard rails.
Everett closures through Monday
The southbound I-5 off-ramp to SR 529 and southbound SR 529 from Ebey Slough to Steamboat Slough closed 11 p.m. Friday, March 28, as WSDOT crews connect the new southbound I-5 off-ramp to SR 529.
Work is expected to wrap up by 4:30 a.m., Monday, March 31st.
Tiger Mountain Pass impacted
WSDOT crews are working on re-aligning the new on-ramp from State Route 18 (SR 18) to eastbound Interstate 90 (I-90). This weekend-long project closed this on-ramp Friday, March 28th, at 9 pm. and is scheduled to reopen Monday, March 31st by 5 a.m.
The March 28-31 work on the SR 18 on-ramp to eastbound I-90 represents the first of two weekend-long ramp closures for the I-90/SR 18 Interchange Improvements project. Beginning Friday night, April 4, the westbound I-90 off-ramp to SR 18/Snoqualmie Parkway will close through Monday morning, April 7, as work continues on a new diverging diamond interchange.
Don’t miss the Monday deadline
Technically, you can still have studded tires on your vehicles through the end of Monday, March 31st. On Tuesday, you’ll be eligible for a fine of $137 dollars.
